Chevrolet Corvette ZR1 to Feature All-New 700-Horsepower Engine

2017 Chevrolet Corvette Z06

Anticipation for the new Chevrolet Corvette ZR1 has grown to a fever pitch. Fans thought they might get a taste at the recent Detroit Auto Show. But alas, Chevy chose to keep the ZR1 under wraps. CarScoops theorizes this may have been a strategic move to focus attention on the all-new design of the Chevrolet Traverse, which admittedly is also big news, but more on the family-friendly side of things.

 

On the track-worthy side of things, the upcoming ZR1 is indeed good reason for excitement. A big reason is what we’ll find under the hood. Details are scant on the new LT5 engine. What we do know is that it is a twin-turbo V8 capable of an excess of 700 horsepower (at least one source puts it at 750 horsepower). It will replace the current GM powerhouse, a supercharged 6.2-liter V8 that powers the Z06 model.

 

The overall design of the ZR1 will have to be altered to support the new engine. Exchanging a supercharger for two turbochargers means that the engine will feature a new cooling scheme. This also means you’ll see air intakes on the front fascia of the ZR1.

 

Word on the street is that we won’t lay eyes on the new Chevrolet Corvette ZR1 until the Continental Tire Road Race Showcase at Road America.

Silent but Deadly: The Chevrolet Colorado ZH2

It makes sense that the US Army is the only party who has access to the Chevrolet Colorado ZH2. Whoever is behind the wheel of this super-truck is the veritable king of the road—an important title when you are engaged in desert warfare.

Specs

The ZH2 is very big, as any proper war machine should. At six-and-a-half feet tall and seven feet wide, this is one intimidating truck. And sitting on 37-inch tires with a “specially modified suspension,” it’s able to leap tall buildings in a single bound! …Well, not really. But it has no trouble negotiating difficult desert terrain.

Design

Despite the belittling effect its size might have on the enemy, the ZH2 is designed for stealth. This is where its unique powertrain comes into play.

Power

A state-of-the-art hydrogen fuel cell powers the ZH2. The Army has employed the truck to study whether hydrogen fuel-cell technology can provide “near-silent operation” and “reduced thermal signatures” — two qualities essential for stealth. Fuel cells also provide high torque, important for off-road operation. The Army is even studying how to use the H2O by-product in the field.

 

Charlie Freese, the man who oversees all things fuel cell at GM, said the Chevrolet Colorado ZH2 is “a terrific example of GM’s engineering and design skill.” It’s hard not to agree.
