Chevy’s 2015 Corvette Z06 makes 650 HP, overpowering McLaren 650S and Viper

When the 2015 Chevrolet Corvette Z06 was unveiled at the Detroit Auto Show back in January, it proved itself a worthy successor to the supercar-slaying C6 model, even though Chevy wouldn’t say exactly how much power it produced.

Now, those power figures have been revealed. It was definitely worth the wait.

The 2015 Z06’s 6.2-liter supercharged LT4 V8 is rated at 650 horsepower and 650 pound-feet of torque. That makes the new Z06 the most powerful production car GM has ever built.

Not only does the Z06 eclipse the old Corvette ZR1’s output of 638 hp and 604 lb-ft, it also overpowers the McLaren 650S and SRT Viper, and is just one horsepower shy of the Ferrari FF’s output.

That record-breaking power output is achieved with an engine based on the same Gen 5 small-block design as the LT1 V8 used in the regular Corvette Stingray. Notable upgrades include a 1.7-liter supercharger, dry-sump oiling, aluminum cylinder heads, and titanium intake valves.

However, the 2015 Z06 won’t be an untamed race car. It’s the first Z06 to be offered as a convertible, and the first with an available automatic transmission. The eight-speed unit targets Porsche’s dual-clutch PDK, and will be offered alongside a seven-speed manual.

While the 2015 Corvette Z06 has yet to turn a wheel in anger, it’s earth-shattering power has already earned it a place in the history books. The Corvette team should be commended for proving that “America’s Sports Car” can run with the world’s supercars.

Mercedes-Benz G580 first drive: old-school off-roader goes electric
2025 Mercedes-Benz G580 from three quarter view.

American car buyers mostly know Mercedes-Benz as a luxury brand. But for decades, the automaker has also produced the tough, rugged G-Class (also known as the Geländewagen or G-Wagen), an SUV not afraid to get its leather upholstery muddy. And now, this iconic Mercedes is going electric.

The 2025 Mercedes-Benz G580 with EQ Technology — the final name of the SUV previously known as the EQG — isn’t the first electric off-roader. The Rivian R1S and R1T and GMC Hummer EV have proven that electric powertrains and off-roading are a great combination. But the electric G-Wagen is different because it’s based on an internal-combustion model — and a very traditional one at that.

Honda believes hydrogen semi trucks will make the case for fuel cells
Honda hydrogen fuel-cell semi truck.

Honda remains committed to hydrogen fuel-cell vehicles, but the market for those vehicles remains limited. So Honda is looking at other uses for fuel cells -- including commercial trucks.

To show how that could work, Honda converted a semi truck to fuel-cell power, replacing its diesel engine with three fuel-cell modules. Together, the three modules produce a combined 321 horsepower, and can propel the truck to a top speed of 70 mph. There's enough onboard hydrogen storage capacity for a 400-mile range with a full load, Honda claims.

Mercedes-Benz G580 vs Rivian R2: Is the much cheaper Rivian actually better?
2025 Mercedes-Benz G580 from three quarter view.

Mercedes-Benz has finally taken the wraps off of the new "Mercedes-Benz G580 with EQ Technology." Yeah, it's a mouthful, but it's basically a new electric G-Wagon. It looks a lot like the G-Wagon you know and love, but with an electric powertrain and a battery. It's not the only electric SUV out there, however, and there are some great ones -- like the Rivian R2.

Both the Mercedes G580 and the Rivian R2 have a lot going for them, but they also approach the electric SUV slightly differently. Is one better than the other? I put the two head-to-head to find out.

The approach that the two vehicles take to design is quite different -- and you might like one better than the other.
