1983 Motorweek showdown pits Porsche 928S vs. Chevy Camaro Z28

Last month, Motor Trend threw the Camaro Z/28 and Porsche 911 GT3 into the bear pit and let them fight it out. Way back in 1983, MotorWeek had the same idea, comparing the Camaro Z/28 to the Porsche 928S. At the time, the Camaro was America's best selling sports coupe, the 928S was Porsche's top-of-the-line model that also had the highest top speed of any car sold here. And the price differential was even more stark then: $13,600 for the Camaro, $45,000 for the Porsche. That put the Z/28's cast-iron, 5.0-liter V8 with 190 horsepower and 240 pound-feet of torque against the all-aluminum 4.7-liter V8 with 234 hp and 263 lb-ft in the 928S. Even with that and the Camaro being 14 inches longer than the Porsche, the American was a surprising 40 pounds lighter than the German. The show took them to Summit Point Raceway in West Virginia to see how close a relative performance bargain could hang with a the German GT. Both had five-speed manual transmissions, but the high-speed corners and tight sections of Summit Point would test other handling variables, including the "bone-rattling" Camaro's solid rear axle and disc and drum brake setup vis-a-vis the four-wheel disc brakes and independent suspension on the "firm-but-smooth" Porsche. Paradoxically, the larger disparity 22 years ago resulted in a closer result. Check out the video to see how the Summit was won.

Porsche GT division rules out AWD, SUVs

Any German automaker worth its lap times needs a performance division. Mercedes has AMG, BMW has the M division, Audi has Quattro GmbH with its S and RS models... even Volkswagen has its R line of hot hatches. And though Porsche is a performance automaker unto itself, even it has a performance division. It's called Porsche GT, and though it's been branching outside the 911 range lately, don't expect it to wander too far. According to Car and Driver, which spoke recently with Porsche GT boss Andreas Preuninger and R&D chief Wolfgang Hatz, there are limits to what the division will do. And while those limits may have been broadened to include technologies like turbocharging and dual-clutch transmissions, they won't stretch as far as all-wheel drive. Take a look at the previous-generation 997 and what separated the 911 GT2 from the 911 Turbo was principally its all-wheel-drive system. Porsche GT isn't planning on doing a GT2 this time around – the new GT3 RS occupying that territory on its own – but the next generation (whether it wears the number 2 or 3) will likely go turbo along with most of the rest of the 911 family. The exclusion of all-wheel drive from the Porsche GT parts bin also means that the division won't be taking on the company's SUVs like the Cayenne and Macan. So the Cayenne GTS will be as extreme as it gets, taking on the likes of the BMW X5 M, Mercedes GL63 and Audi SQ5 without the help of Zuffenhausen's racing department. We can't expect the PDK to stick around though, so to speak. Though the new Cayman GT4 packs a manual transmission, the 911 GT3 and GT3 RS have dual-clutch gearboxes. Moving forward, Preuninger says they'll leave it up to prospective customers to decide which type of transmission they'll build into their most extreme performance models.

Porsche reportedly working on new turbocharged flat-four boxer engine?

These days, we've seen just about every automaker dropping cylinders in an effort to appease tightening fuel economy and emission standards - and Porsche is no exception. Nearly three years after introducing an all-new V6 powerplant under the front hood of its Panamera sedan (launched with a range of V8 engines) comes word that Porsche is working on an all-new turbocharged flat-four boxer to replace the flat-six engines mid-mounted in its Cayman and Boxster models.
Specifics have yet to be learned, but reports say the engine is a derivative of the current 3.8-liter six (shown above) found under the rear decklid of the Carrera S, yet with two fewer cylinders. Fitted with a turbocharger, direct-injection and the automaker's VarioCam Plus, the new all-aluminum 2.5-liter flat-four will likely develop upwards of 350 horsepower and 360 pound-feet of torque. Redline should be about 7,500 rpm. Initial indications say that Porsche will only offer the new engine with its seven-speed PDK dual-clutch automatic, tuned to take advantage of the low-end torque, but a traditional six-speed manual gearbox has not been ruled out. Despite the loss of two cylinders, enthusiasts will likely embrace the new engine as it promises to be lighter, more fuel efficient and more powerful than the 2.7-liter and 3.4-liter sixes in the Cayman/Boxster today.
Even though Porsche has been using Volkswagen Group engines for years (e.g., Cayenne V6, Cayenne Diesel and upcoming Macan), all indications are that the new flat-four will not be shared. Instead, it will be kept in-house for the automaker's sports cars and possible future fitment in an entry-level 911.
