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.

Driving McLaren's Sports Car and 'The Best Corvette' at the M1 Concourse | AutoblogVR

There's nothing better than a track day. Great cars on a great track are always great fun. Recently, we had the opportunity to check out the new M1 Concourse in Pontiac, MI, with two of the coolest cars in the game; a McLaren 570S and a Corvette Grand Sport. Driving the 570S was Autoblog senior editor Greg Migliore, and he didn't hold back. Getting behind the wheel of the McLaren, Greg explains that although this is McLaren's idea of a sports car, "it's all relative." Topping out at 204 miles per hour with 562 horsepower, there's no two ways about it: this thing is a monster. While the 570S was fantastic, we had another sports car we wanted to drive and editor-in-chief Mike Austin was just the man for the job. Enter the Corvette Grand Sport. Mike pushed all 460 horses of the 'Vette to the limit and came away impressed with the car, even calling it "the best Corvette." Comparing it to its more powerful sibling, the Z06, Mike goes so far as to say the Z06 has too much power, while the Grand Sport seems to be the third bear's bowl of porridge in the Corvette family... It's just right. We captured all the action of the day with 360° cameras so you can feel like you're right there in the car sitting shotgun with us! You can check out the McLaren and Corvette laps above, but the best way to view them is through the AutoblogVR app, where you can watch the videos on your VR headset or in a nice swivel-y office chair so you can take in the sights all around you. Each month, new episodes will launch on the AutoblogVR App. We'll be posting them here on Autoblog, but for the best experience, head over to the app, which you can download for free from the App store and Google Play. Be sure to try it with a cardboard viewer, too!

GM pauses 3.0-liter turbodiesel production due to a supplier shortage

General Motors confirmed it has temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine. It blamed the last-minute pause on a supplier-related shortage. Website TFL Truck first reported the news, and a representative from General Motors quickly confirmed it. The spokesperson explained the issue is due to a "temporary part shortage" and added that production will resume "as soon as possible," meaning the Duramax engine (which is called LM2 internally) is not going away permanently. Additional details are not available, so we don't know if the issue is related to the ongoing chip shortage. Rather than delay deliveries and create a backlog, General Motors is reportedly asking its dealers to encourage buyers who want a turbodiesel engine to instead select either the 5.3-liter V8 or the 6.2-liter V8, depending on the model selected. Both are gasoline-powered units. There's no word yet on when Duramax production will resume. The shortage affects several models, including Chevrolet's Tahoe, Suburban, and Silverado 1500 and GMC's variants of these trucks. Cadillac's Escalade is temporarily diesel-less as well. Heavy Duty variants of the Silverado and the Sierra are not affected because they're powered by a different Duramax engine with eight cylinders. Motorists seeking a full-size SUV powered by an efficient turbodiesel engine are temporarily out of options because the Tahoe/Yukon and the Suburban/Yukon XL had the segment to themselves. The Duramax was surprisingly popular, too: in May 2021, GM Authority reported that the turbodiesel straight-six represented 8% of Suburban sales and 6% of Tahoe sales. Installed in a rear-wheel-drive Tahoe, the engine returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make the body-on-frame behemoth more efficient than the unibody, front-wheel-drive Chevrolet Blazer that's 20 inches shorter and approximately 1,700 pounds lighter.
