2012 Chevrolet Camaro ZL1

2012 Chevrolet Camaro ZL1

It’s an epic, decades-long battle waged in showrooms, at the race track, at stoplights, and in internet forums. Chevrolet versus Ford, Camaro versus Mustang. Commencing in the mid-’60s, the clash has been marked by tit-for-tat product introductions, as each brand seeks to match its competitor in every conceivable pony-car niche. Currently, the cars face off in the V-6, V-8, and droptop arenas, but the latest Camaro has ceded the high-performance crown to the Mustang and the brutal, 550-horse Shelby GT500. That ends now.

Welcome the reborn Camaro ZL1.

Open Secrets are Hard to Keep

It’s been a bit of an open secret that GM was working on a high-po Camaro to slot above the 426-hp SS model. Spy photos revealed the car’s 6.2-liter supercharged V-8, and most assumed that car would wear the storied Z28 badge. But Chevy’s product planners had something different in mind, and we now know the car will wear the reclaimed ZL1 moniker. (SLP Performance previously held the rights to the historic alphanumerics.)

A quick look back is in order. The 1969 Camaro ZL-1 was one of the ass-kickingest machines to ever roll out of Detroit. Dressed up in nothing fancier than base Camaro trim—including dog-dish hubcaps—that original ZL-1 looked like a measly six-cylinder wimp. Without even an engine-designation badge, its only real giveaway was the factory-installed cowl-induction hood. (Well, until you started it up and brought the aluminum big-block 427 to life.) The car was only available via Central Office Production Order (COPO), which installed the 427 option in the Camaro shell. Just 69 copies were built, and the ZL-1’s official 430-horse output figure was grossly underrated, mainly for insurance purposes. It was a quarter-mile king, and is among the quickest factory-built and street-legal beasts ever created.

Back in the present, the 2012 ZL1 aims to grow the legend, and it comes well prepared with a supercharged LSA V-8, borrowed from the Cadillac CTS-V. Producing an estimated 550 hp—a figure on par with the actual output of the original—and 550 lb-ft of torque from its force-fed 6.2 liters, this burly Camaro is seemingly built to terrorize drag strips rather than road courses, so perhaps ZL1 is more appropriate than Z28. (The Z28 was a racer, after all, competing and winning in Trans-Am.) A short-throw, six-speed Tremec manual is the only transmission.

Aiding driveline longevity and pavement adhesion are a beefed-up driveshaft and differential with asymmetrical half-shafts; the latter twist fat, 305-width ZL1-specific Goodyear Supercar F1 gumballs. The 20-inch forged wheels are 10 inches wide in the front and 11 in the rear, but the overall wheel-and-tire package is 22 pounds lighter than the Camaro SS's narrower 20-inch setup. We (conservatively) estimate the ZL1 will cover the 0-to-60-mph run in four seconds flat, while 0 to 100 mph should be accomplished in 9.9 seconds and the quarter-mile in 12.5. Monstrous two-piece Brembo rotors—measuring 14.6 inches in the front and 14.4 in the rear, and squeezed by six- and four-piston calipers—are the centerpieces of the braking system. The latest adaptive magnetorheological shocks sit at all four corners, and drivers can choose between Tour and Sport settings. The ZL1 also marks the introduction of a new electric power-steering system. Weight is said to be about the same as the Camaro SS's—the stronger driveline added weight, but some was pulled out with stuff like the wheels and hood, so it's roughly a wash—which puts this top-spec Camaro at 3900 pounds or so.

Many More Pieces of Flair

While the sleeper look of the original was awesome, the new ZL1 will be highly differentiated from its lesser kin. Up front, the lower fascia is dotted with brake-cooling ducts and four fog lights, and has a large splitter and a wide-mouth intake. The domed hood is aluminum with a louvered carbon-fiber center section that Chevy says helps downforce, while the rear end gets a larger integrated decklid spoiler and quad exhaust finishers. The exhaust system houses an actuated flap, as on the Corvette, that opens at higher engine speeds to both reduce back pressure and deliver a blood-boiling growl.

The cabin gets a few modest upgrades, including alloy pedal covers, a head-up display, and emblems for the headrests and door sills. Sueded material is applied to the shifter, the new flat-bottomed steering wheel, and the front-seat inserts. The auxiliary console gauges are standard on the ZL1, and feature a boost readout that we wouldn't recommend actually looking at while behind the wheel—keep your eyes on the road, please.

We're told the ZL1 will start around $47K, although Chevy could revise the pricing upward later, and it's unknown if the model will get hit with a gas-guzzler penalty. Unfortunately, we’re going to have to wait to get our hands on this brute, as it doesn't go on sale until February of 2012. So the GT500, which costs $49,495, will gallop on unchallenged for a little longer. And what about the more-racetrack-oriented Mustang Boss 302? Maybe the Z28 will find a place in Chevy’s modern lineup after all .

2012 Chevrolet Camaro


The first time we experienced a major oil shock—the Disco-fabulous 1970s—it eviscerated the muscle-car scene, leaving us with neutered behemoths constructed with all the care of a North Korean knock-off Benz. In comparison, as today’s crude oil and prices at the pump again head north, muscle-car fans are still coming out winners. Ford’s Mustang Boss 302 is a track-attacking monster. And now Chevy is actually increasing the standard horsepower in its base V-6 2012 Camaro, from 312 to 323, while maintaining a 30-mpg highway rating.

Happy Birthday to You

For the hard-core Camaro community, though, the bigger news is the 45th Anniversary Edition Camaro. While a 45th birthday is less noteworthy than a 50th, who wants to wait another five years? By then, the Camaro will probably be a wheatgrass-electric hybrid. The 45th Anniversary package is available for the top-spec Camaro regardless of engine, and dresses up the car’s exterior with asymmetric hood and trunk-lid stripes, new-design 20-inch rims, a spoiler, and HID headlamps. Inside, the package splatters 45th Anniversary logos all over the place—seats, dash, instrument panel, steering wheel, sill plates—and trims the seats, steering wheel, shift boot, armrests, and center console in red, white, and blue contrast stitching. Disappointingly—but not surprisingly—it offers no performance upgrades. It should, however, look very sharp at the local Sunday-morning car club, alongside owners clad in Camaro hats, T-shirts, and windbreakers, clutching Camaro key chains and Camaro thermoses.

As for that smaller engine, GM’s 3.6-liter V-6 is its workhorse, powering everything from the Cadillac SRX (as of yesterday) to the Buick LaCrosse. The Camaro’s version is now dubbed LFX (in the past it was called LLT), and it makes 323 hp versus last year’s 312. The engine has longer-duration camshafts and an improved head design with larger intake valves. It drops 21 pounds, mostly thanks to a composite (read: plastic) intake manifold and lighter connecting rods, and Chevy says it is still good for 30 mpg on the highway.

On the dynamic front, engineers went to work on the chassis, sorting the stiff ride of the V-8-powered Camaro SS. The new suspension features retuned front and rear dampers, and new solid anti-roll bars front and rear. You know the drill though—we’ll believe it when we drive it.

Bye, Bye, Miss Steering-Wheel Pie

General Motors was also kind enough to clean up the Camaro’s interior for 2012. Most notably, the deep-dish steering wheel—the bane of people everywhere who like steering wheels—is gone, replaced with Chevrolet’s corporate tiller. The gauges dump the retro font from last year’s car, and the monolithic slab of cheap plastic that used to span the majority of the dash has been replaced with several smaller panels. (We just hope the quality is better.) To deal with the Camaro’s pillbox-inspired visibility problems, Chevy added a standard rear spoiler. Since there will now be absolutely no rearward visibility, a rearview camera system is available; it displays the image on a screen located in the rearview mirror.

If visibility is the only compromise we have to make with the new Camaro—and Chevrolet seems to be trying hard to provide it all in terms of power and economy—then it’s just another welcome sign that the 2010s will be a lot gentler on the auto industry than were the ’70s.

Porsche, 2012 Porsche Panamera S Hybrid

Porsche, 2012 Porsche Panamera S Hybrid
Volkswagen's corporate parts bin is a great resource, and it's something from which all of its brands get to pluck. This includes Porsche, which took the easy route of adding a gas-electric version to the Panamera lineup by performing a little hybrid-system transplant surgery. The result, the 2012 Panamera S hybrid, makes its debut at the 2011 Geneva show.

The combination of a supercharged, direct-injected 3.0-liter V-6 and an electric motor is not only used in the Cayenne, but also in the Volkswagen Touareg hybrid; the 333-hp gasoline engine is an Audi unit that, in different states of tune, can also be found sans hybrid tech in the S4, S5 convertible, A6, and Q7. With the assistance of a 47-hp electric motor, total power reaches 380 hp, channeled here only to the rear wheels through an eight-speed automatic transmission. All other Panameras sold in the U.S. come with a ZF-supplied seven-speed PDK dual-clutch transmission, while Europeans also can choose a six-speed manual.

Porsche believes the Panamera hybrid's performance is good enough to justify adding the "S" badge. In reality, however, its performance may be closer to that of the standard, V-6–powered Panamera. With the hybrid, Porsche claims a 0-to-60-mph time of 5.7 seconds; top speed is 168 mph. The last 300-hp base Panamera we tested, equipped with the PDK and aided by all-wheel drive, hit 60 mph in 5.0 seconds and went on to a top speed of 160 mph. The corresponding data for the 400-hp, V-8–powered Panamera S: 4.7 seconds and 174 mph. That said, Porsche tends to conservatively estimate performance, but the lack of the fast-acting PDK transmission and all-wheel drive likely will hamper the hybrid’s launch.

Despite all of the power, the hybrid should shine in terms of fuel consumption, at least in the city. The regular Panamera S is rated for 16 mpg city/24 highway, and we (conservatively) estimate that the hybrid will return 21 mpg in the city and 25 highway. We'll have to wait for the EPA to rate the car for official figures.

What's a hybrid without the option to drive in full-electric mode? Maybe not as satisfying, as buyers of the Mercedes-Benz S400 hybrid are experiencing (or, rather, not experiencing). But the Panamera won't disappoint: Drivers can accelerate up to 50 mph on electricity alone, although the range in this mode is just 1.3 miles. Additionally, when the driver lifts off the accelerator at higher speeds, the gas engine will shut off and then be declutched from the drivetrain. Porsche calls this "sailing"; we'd call it coasting, and with the function active up to 103 mph, the cops will sometimes call it speeding.

The Panamera hybrid competes in principle with other hybrid luxury sedans such as the aforementioned 295-hp Mercedes S400 hybrid, the 455-hp BMW ActiveHybrid 750i/Li, and the 438-hp Lexus LS600hL. While the Porsche shares its six-cylinder approach with the less-expensive Mercedes, the capacity to drive on electric power alone puts it on a par with the Lexus. All of these luxury cars have one thing in common: In Europe, their fuel economy is bested by their available diesel counterparts. Should Porsche opt to add a diesel to the Panamera lineup, the hybrid is sure to lose its position as the most efficient Porsche sedan.

For now, however, it wears the politically correct crown—and to flaunt it, there are hybrid badges placed prominently on the rear, as well as on the front doors. The Panamera S hybrid will start at $95,975, which is about $5000 more than the faster Panamera S, but it is also better equipped, as the normally optional adaptive air suspension and speed-sensitive steering are standard here. Look for the Panamera S hybrid at dealerships this summer.

Porsche, 2012 Porsche Panamera Turbo S

Porsche, 2012 Porsche Panamera Turbo S

It was inevitable—and reported by us just yesterday—that Porsche would further extend its Panamera range. Just a couple of years after the launch of the Panamera Turbo, Porsche is adding a Turbo S to the lineup by squeezing another 50 hp out of its awesome 4.8-liter, twin-turbo V-8. This model is not exactly a surprise: The Panamera’s V-8 engines are shared with the Cayenne, and the last-generation Cayenne was already offered with a 550-hp variation. (Here's a wild prediction: Porsche will add a new Cayenne Turbo S soon.)

The Panamera is a big and heavy car, but it shines as it thunders down the road at surreal speeds. Modified engine management and improved titanium-aluminum turbochargers enable the aforementioned 550 hp, as well as 553 lb-ft of torque, up from 516 for the regular Turbo. In the chassis’s "Sport" and "Sport Plus" modes, an overboost function increases the twist to a wild 590 lb-ft. The regular Turbo can muster an already-impressive 568 lb-ft under overboost, which is accessed by paying for the Sport Chrono package. This package is standard in the Turbo S.

The added power translates into performance you won't need to complain about: Porsche says 60 mph can be achieved in 3.6 seconds, but we clocked the regular Turbo at 3.3. Figure a tenth or two quicker than that, thanks in large part to the seven-speed dual-clutch PDK automatic, which includes a launch-control function. It is the only available transmission. The company claims a top speed of 190 mph, but based on our testing, the real-world figure will be higher by about 5 mph. If you care, Porsche has no final fuel-economy ratings yet, but it says they will be close to the Turbo’s city/highway figures of 15/23 mpg.

No major changes were made to the chassis, which can be considered supremely competent even among high-performance sedans, but the rear track has been engorged by specific 20-inch Turbo II wheels. Europe gets the option of low-rolling-resistance tires on 19-inch wheels, which increase efficiency—yippee!

The slight performance increase comes at a not-so-slight premium. Porsche is asking for a cool $174,175, as opposed to the $136,275 required for a Panamera Turbo. For that money, you get some of the Turbo’s performance options as standard (Porsche Dynamic Chassis Control, Sport Chrono, etc.), as well as side skirts out of the "Porsche Exclusive" parts bin and the choice of special color combinations. Agate gray metallic is exclusive to the Panamera Turbo S, and inside there are two color combos—black/cream and agate gray/cream—that you can't get on any other Panamera. We predict these color choices will prove to be especially popular among Turbo S customers, who will be eager to point out to their friends exactly what they got for an extra $38K. (It’s worth mentioning that Porsche also offers a $21,000 Power Pack to upgrade your Panamera Turbo to 540 hp, but it doesn’t include all the S goodies.)

The spacious Porsche hatchback remains the second-fastest sedan in the VW Group—the Bentley Continental Flying Spur Speed has a top speed of 200 mph—and that’s not likely to change for a while, at least until the Bugatti Galibier comes to market. And, if anything, it will serve as a nice benchmark for Audi and its upcoming RS6. Is anyone else enjoying VW Group’s high-powered supersedan civil war as much as we are?

2014 Mini Cooper Hybrid

2014 Mini Cooper Hybrid

Due in about three years, the next-generation Mini Cooper will offer a four-wheel-drive version. There’s a catch, though: The rear wheels will have no connection to the engine. The car will be a hybrid, and the rear wheels will exclusively be turned by an electric motor.

As BMW switches the next-generation 1-series to front-wheel drive, and expands the Mini portfolio with several new models, the Bavarians are looking at options for hybridizing its upcoming front-wheel drivers. To expedite the process, BMW recently announced a partnership with PSA Peugeot Citroën to develop hybrid tech for front-drive applications. Although BMW presently offers hybrid versions of its X6 and 7-series, each uses a rear-wheel-drive-oriented system co-developed with other companies—and neither is especially frugal. PSA, on the other hand, is launching the Peugeot 3008 Hybrid 4 this year, a compact MPV on a front-wheel-drive platform with a rear-mounted electric motor powering the rear wheels. BMW seems to see its smaller cars heading in this direction.

In this test mule, we can see that the electric motor is connected to the rear axle. The extra power and enhanced launchability should give it a decisive advantage over front-drive Minis, and while the motor and battery pack will add unwelcome weight, at least they’ll be mounted low in the chassis. That said, the production cars won’t be quite as low to the ground as the mule seen here. The hybrid module will likely be offered in a number of Mini derivatives; from the “regular” Mini Cooper up to the Countryman.

It’s not yet clear what kind of combustion engine Mini will pair with the electric drive system, although both diesel and gasoline mills would be compatible. The hybrid won’t share much technology with the Mini E, and we are optimistic that—unlike in that fully electric Mini—rear seating will be part of the package.

Like the original Mini, today’s Cooper is most at home in cities, and it’s in the slow, stop-and-go traffic that hybrid systems best deliver their benefits. The Mini remains hot for fashionable urban drivers, and it’s possible that a hybrid version will up the chic factor for these shoppers—even if it is very late to the eco-party.

How will the hybrid versions be positioned in the Mini lineup? Peugeot priced the 3008 hybrid at the very top of the car’s price ladder. With more power and all-wheel drive, the hybrid Minis are likely to be the most expensive in their ranges, too. It also remains to be seen how much the extra weight and complexity will diminish the Mini models’ playful character.

Subaru, 2011 Subaru Legacy 2.5GT Limited

Subaru, 2011 Subaru Legacy 2.5GT Limited

Testing Subaru’s Legacy 2.5GT Limited has proven frustrating. And expensive. In its initial acceleration runs, our first GT sheared a half-shaft. Once repaired, the car made a second appearance, and a second half-shaft was bifurcated.

As another GT arrived, so, too, did the season’s first blizzard, an Arctic apocalypse that would have cowed  Admiral Peary and easily overwhelmed the Legacy’s 18-inch summer-spec Bridgestones. What luck, huh?

The 2.5GT Limited, starting at $32,120, represents the sportiest of Legacy sedans. Its turbocharged 2.5-liter four produces 265 horsepower—95 horses beyond what the base 2.5i can muster, and nine more than the 3.6R’s 3.6-liter flat-six.

With half-shafts finally spinning instead of flailing, the 2.5GT tackled 60 mph in an aggressive 5.4 seconds, and the quarter-mile was dispatched in 14.1 seconds at 100 mph. By contrast, the base Legacy, fitted with a CVT, required 8.7 seconds to attain 60 mph. And the flat-six, with standard five-speed automatic, performed the task in 6.4.

The 2.5GT Limited comes with a six-speed manual only, and ours was gussied up with a short-throw kit, part of an unnecessary $1154 option pack that includes a boost gauge that looks like a geothermal event bulging up through the dash. Clutch feel is dandy, but the shifter’s gates are resistant and overall effort is high. At step-off, moreover, clutch slipping is sometimes necessary to coax  the all-wheel drive’s many cogs, pinwheels, and whirligigs into motion.

The GT’s suspension is buttoned down, with body motions conscientiously controlled, and the ride remains settled and ­supple. The steering is oddly heavy and somewhat leaden at low speeds but sharpens acceptably as digits accrue. Funny that Subaru  has spent tens of millions to acquire a legitimate rally heritage, yet this car is ­fitted with no hand brake.

Just north of 2500 rpm, the engine climbs on boost, summoning a butt-wallop that many of us last experienced in grade school. It’s a sudden kick in the pants that reliably illuminates traction-control warnings if the road is damp.

Unfortunately, peaky powerplants also have the habit of snapping heads. The 2.5GT is fun, but it’s a car that proves tricky to drive smoothly. Which had us yearning for the refinement and more-than-adequate perform­ance of the 3.6R, which fetches $6400 less than the 2.5GT Limited and thus earns our nomination as the Legacy for discriminating adults.

Subaru, 2011 Subaru Impreza WRX Sedan

Subaru, 2011 Subaru Impreza WRX Sedan

In the years since its 2002 U.S. introduction, the rally-inspired Subaru Impreza WRX evolved aesthetically like Barry Bonds, morphing from the scrawny-looking yet scrappy original to this version, the beefed-up and muscular 2011 model. Yes, there were a few stylistic missteps along the way, 2006’s funky nose and the softer look of the 2008 chief among them, but we’ve never loved the WRX for its looks. This vehicle has always been a blast to drive, and it got even better for 2009 when Subaru poured on 41 more hp, for a total of 265, and stirred in a raft of chassis revisions. The result was a 0-to-60-mph run of 4.7 seconds and more poise than ever; the only remaining issues were a tendency to understeer and styling too much like a regular Impreza’s. You may now consider these concerns rectified.

Updated Inside, Out, and Underneath

This year, the WRX sedan and hatchback receive the aggressive, wide-body design of the more powerful STI, including its quad-tipped exhaust. Track increases of 1.3 inches in front and 1.5 inches in the rear—coming in part from the lighter, wider 17-inch wheels (eight inches wide versus seven)—ensure that the newly flared fenders are filled. As expected given the wheel widening, the Dunlop SP Sport 01 skins increase in width from 225 millimeters to 235. The chassis changes are rounded out by stiffer rear subframe bushings.

Inside, new carbon-colored trim accents the top of the dash. We like the color, but among the dash, center stack, and console, there are three different silver/gray hues, which together look a bit chintzy. A revised audio system includes Bluetooth and iPod connectivity as standard; it’s the only other major interior change for 2011.

Now with More Fun!

The small alterations to the footprint improve the WRX’s ride and handling as much as the burlier styling enhances its look. Previously, the WRX pushed when approaching the limit—although a four-wheel drift was (and is) always a throttle-lift away—but the newly widened stance has made it absolutely neutral. It’s not apparent in the test data (skidpad grip was up a touch to 0.89 g from the 0.87 g posted by the last WRX tested on these Dunlops), but toss the “Rex” into a corner and now neither front nor rear will let go without the other unless your inputs are overly aggressive. This composure at the limit vastly increases driver confidence, which is further enhanced by reduced body roll and steering that feels sharper and more responsive than the previous car’s. In short, the WRX finally feels at home on a track. As a bonus, getting there is more enjoyable, thanks to an incredibly refined ride.

Although we’d prefer better initial brake bite and a shifter that doesn’t feel so rubbery—a very good short-throw shifter is
available as an accessory—we can’t ask for much more than the punch delivered from the carry-over turbocharged 2.5-liter. The old-school, turbo-lagged initial delivery of its 265 hp and 244 lb-ft of torque isn’t exactly linear, but the shove and the wild flat-four bellow above 4000 rpm are quite exhilarating. This test car reached 60 mph in five seconds flat and covered the quarter-mile in 13.7 at 100 mph. Although the former number doesn’t match the 4.7-second pace of the 2009 model, it’s in the same neighborhood, and we’d be more than happy to trade a little straight-line performance for the improved handling.

A True Performance Bargain

A base WRX sedan starts at $26,220—$530 more than in 2010—and the car tested here came equipped with the Premium package ($2500) and navigation ($2000) for an as-tested price of $30,720. The Premium package adds fog lights, a sunroof, a rear spoiler, and heating elements for the front seats, mirrors, and windshield-wiper rest. If it were our coin, we’d skip the pricey extras and just add the short-throw shifter for $355.

The WRX has changed quite a bit in the years since its introduction, and the 2011 enhancements have produced the greatest-driving iteration yet. Perhaps best of all, it remains among the few standout enthusiast machines available for less than $30,000, proving that when a car makes big strides, the sticker price doesn’t have to follow suit.
