Chevrolet’s new fire-spitting 640hp Camaro ZL1 breaks cover

2017 is a big year for Chevrolet when it comes to electric vehicles. Between the second-generation Volt and the forthcoming Bolt, the company is in a race with Tesla to see which manufacturer will be the first to sell 200,000 EVs and lose the IRS tax credit. But lest you think that GM only cares about efficiency and being kind to the environment, think again. Today, it took the wraps off a new track monster—the 2017 Camaro ZL1. Under the hood is a supercharged V8 (the 640hp/477kW 6.2L LT4) and General Motors' all-new 10-speed automatic transmission.

The ZL1 has also been on a significant weight loss program. It's 200lbs (91kg) lighter than the previous ZL1, but the new car has an extra 60hp (45kW) and 80ft-lbs (109Nm) to play with. Although you can get the ZL1 with a conventional six-speed, the new automatic gearbox sounds rather interesting. Several years ago, Ford and GM decided to collaborate on a new generation of automatic transmissions for rear-wheel drive cars and trucks—this is the first application of that project to come from Chevrolet, although with some parts and software unique to the ZL1.

The car has also had an aerodynamic facelift to distinguish it from lesser Camaros—but more importantly, to aid high-speed stability and improve cooling. Chevrolet's Corvette Z06 supercar has faced criticism that it overheats too quickly on track—a shame given that it's so ludicrously fast that the track is the only real place it has to stretch its legs. GM will be hoping the same isn't true for the ZL1, which uses the same engine.
