Toyota’s track-honed Sienna R minivan eats the Chevy Camaro SS for breakfast

Toyota is pushing the boundaries of market segments as we know them at this year’s SEMA show. In addition to a 26-foot long, nine-seater limousine based on the Tundra truck, the company is displaying a heavily-modified Sienna minivan that’s designed specifically to hit the track.

The sports van — a phrase combining two terms that, at first glance, seem to be mutually exclusive — was built with input from a California-based performance shop named DG-Spec. Dubbed Sienna R-Tuned, the concept gains performance wheels and tires, racing brake pads on all four corners, and a new suspension setup that includes track-proven parts such as double-adjustable shocks, a custom rear ride-height adjust system, as well as racing springs designed by Vogtland.

Toyota managed to shave over 700 pounds from the Sienna’s weight by removing bulky components such as the second and third rows of seats, the rear A/C, and the roof rails. Additionally, the van has been upgraded with a carbon fiber hood, a lightweight battery, and front bucket seats with six-point harnesses.

A behind-the-scenes look at the Toyota Sienna R-Tuned concept

What’s surprising is that the only major mechanical modification is the addition of a limited-slip differential. The Sienna R-Tuned is equipped with a bone-stock, 3.5-liter V6 engine that makes 266 horsepower and 245 pound-feet of torque, and a six-speed automatic transmission sourced directly from the Toyota parts bin.

When it’s done hauling kids to and from baseball practice, the Toyota Sienna R is capable of racing around the 1.7-mile long Willow Springs race track in one minute and 27 seconds. By comparison, the 2015 Chevrolet Camaro SS — which boasts a massive, 6.2-liter V8 rated at 426 hp — is a full second slower.

Speed junkies who can’t wait to take their kids to school in a hot-rodded, Camaro-punching minivan shouldn’t hold their breath. The Sienna R-Tuned is simply a concept designed for the SEMA show, and Toyota isn’t planning on building it.

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.
