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.

General Motors Recalls Nearly 780,000 Cars To Fix Deadly Problem

General Motors is recalling nearly 780,000 compact cars in North America because the engines can shut down unexpectedly and cause crashes. The company says six people have been killed in crashes related to the problem. The recall affects Chevrolet Cobalts and Pontiac G5s from the 2005 through 2007 model years. U.S. safety regulators say the weight of the key ring and rough roads can move the ignition switch out of the run position, cutting the engine and electricity. If that happens, air bags may not work. GM says there have been 22 crashes from the problem. All happened at high speeds. Dealers will replace the ignition switch for free. GM says owners should remove nonessential items from key rings until the problem is fixed.

GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.
