Volvo Polestar unveils a 620+ horsepower V8. Yes, you read that right

Think that Volvo is a boring automaker, not capable of some mean muscle? Think again because the Swedes at Polestar, a Volvo performance company, have just unveiled their new V8 engine designed for the V8 Supercar racing series in Australia.

Volvo says is the first luxury automaker to join the series. Perhaps it’s forgetting the Mercedes-AMG team? Regardless, usually dominated by Ford and GM, the V8 Supercar series should be a bit more exciting with Volvo running the races.

The engine is called the B8444S and it’s an aluminum 60-degree block with direct injection and a redline of 7500.

Polestar engineers took its Yamaha-sourced 4.4-liter V8 and bored it out to 5.0 liters and upped compression to 10:1. Volvo hasn’t said how much power it churns out but the series requires between 620-650 horsepower. The normal, 4.4-liter production version only makes 311 hp. So doubling its power is a pretty impressive feat considering it’s naturally aspirated and not turbo or supercharged.

If you’ve never watched V8 Supercar, I suggest you check some of the races out on YouTube. It’s one of the last remaining rear-drive road course races. It has all the rough and tumble action that used to keep American on the edge of their seats before they lost interest in racing virtually altogether.

How will Volvo do against Holden, Nissan, AMG, and Ford? We’ll have to wait and see. If you’re a Volvo nerd like me, you’ll want to check back for highlights.

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.
