Corvette Z06. Nissan GT-R Nismo. Motor Trend Head 2 Head. 'Nuff said.

Here is a video we've been waiting for, one that will get broadband fiber optic cables glowing like Hooker headers on a dyno. For Episode 62 of Head 2 Head, Motor Trend throws the 2015 Chevrolet Corvette Z06 into the bear pit with the latest Nissan GT-R Nismo. What comes out of that is seventeen minutes of don't-look-away video. We're only going to give you the specs. The 3,527-pound Z06 gets on with a supercharged 6.2-liter V8 with 650 horsepower and 600 pound-feet of torque, applied to the wheels via a seven-speed manual transmission. With the Z07 performance package appended it has a front splitter and winglets, and a three-section rear spoiler among its aero aids. The tested model also wore carbon ceramic brakes, which helped push its $89,985 MSRP out to $105,210. The 3,881-pound GT-R Nismo plays the underdog – again – with a 3.8-liter twin-turbo V6 spitting out 600 hp and 481 lb-ft, yoked to a six-speed dual-clutch transmission. The GT-R left its 'performance bargain' days behind years ago, and this top-shelf version starts at $151,585 but has almost everything it can get, so the as-tested price was only a skosh more at $151,880. We're not going to tell you any more than that. Click on the video and let Carlos Lago and his two mean minions tell you a story you won't soon forget.

Leak reveals GM's 2017 heavy duty diesel trucks to get 910 lb-ft of torque [UPDATE]

UPDATE: Chevrolet officially announced specs for the 2017 Silverado HD and the rumors were true. The truck's new Duramax 6.6-liter turbo-diesel V8 puts out 445 horsepower and 910 pound-feet of torque. Chevrolet says the new motor produces 19 percent more torque and 12 percent more horsepower, while producing 35 percent fewer emissions. Overall, the new engine is a big improvement over the current motor, which generates 397 horsepower and 765 pound-feet of torque. According to Truck Trend, GM's newest heavy duty pickup trucks will pick up quite a bit more power and torque. The publication spotted a recent GM Powertrain ordering catalog that had the engine specs for the 2017 model year and managed to get some screenshots before the catalog was taken down, and they can be viewed here. The screenshots revealed that the 6.6-liter turbodiesel V8 powering the Silverado and Sierra heavy duty models will boast 445 horsepower and 910 lb-ft of torque. This is a substantial gain over the current models' 397 horsepower and 765 lb-ft of torque, and as Truck Trend points out, it exceeds the Ford Super Duty line's horsepower output of 440, but comes short of the 925 lb-ft rating. Truck Trend credits part of this output gain to the new intake system GM will introduce on the 2017 heavy duties. The intake gets 60 percent of its air from a scoop on the hood, with the other 40 percent coming from behind one of the front fenders. GM doesn't reveal horsepower figures in the press release about the scoop, but it does say the cooler air helps with maintaining the engine's output, and that the scoop does produce a ram-air affect, providing more air at speed. As we know, more air plus more fuel equals more power, but there's likely more to the power increase in this engine than only the intake.

'84 MotorWeek Cherokee, Bronco and Blazer comparison indulges your SUV nostalgia

These days, truck-based, full-frame SUVs are somewhat of a rarity on the auto landscape due to the rapid rise in popularity of easier-driving, car-based crossovers. Although, without the gradually building popularity of these chunky, high-riding vehicles decades ago, it's unlikely that America's roads would be filled with so many CUVs today. In its latest dig into the archives, MotorWeek has found a 1984 comparison test of a trio of these early Sport Utility Wagons, as long-time host John Davis called them, that helped get acceptance of this segment going. This is a red, white and blue test of the SUVs from American automakers at the time and pits the Chevrolet Blazer, Ford Bronco and Jeep Cherokee (specifically in Wagoneer guise) against each other. Driving manners and interior usability are considered in the evaluation, but Motorweek actually takes these vehicles off road, too. Among the bigger revelations is the improvement in on-road ability in the past 30 years. While specific 0-60 times aren't given, all three models take around 10 seconds just to get to around 50 miles per hour in the 500-feet on-ramp acceleration test. Check out this clip to see just how far this segment has progressed in the past three decades or just get a blast of nostalgia from these now vintage models.
