SUV love killed America’s most ambitious efforts to boost fuel economy

It’s still not clear who killed the electric car, but it’s apparent who did in the efficient one: We did.

In 2012, the Obama administration unveiled new Corporate Average Fuel Economy (CAFE) standards that required carmakers to achieve a fleet average of 54.5 mpg by 2025. The target, which is actually closer to 40 mpg in terms of the figures consumers see on window stickers, was the most ambitious of its type ever enacted in the U.S.

But now the regulatory agencies overseeing CAFE are backtracking. The Environmental Protection Agency (EPA), National Highway Traffic Safety Administration (NHTSA), and California Air Resources Board (CARB) now say the 54.5-mpg standard is off the table, according to Automotive News (subscription required).

The decision came as part of a scheduled assessment of carmakers’ progress toward improving fuel economy. And here’s the zinger: CAFE standards must be reassessed not because carmakers aren’t improving efficiency, but because consumers don’t want to buy efficient cars, regulators said.

The auto industry is “adopting fuel economy technologies at an unprecedented rate,” the agencies said in a statement. They also said carmakers have been able to meet current regulations at the same cost or less than predicted in 2012, and will be able to meet upcoming standards with improvements to gasoline engines, rather than heavier reliance on hybrids and electric cars.

What regulators didn’t account for was Americans’ insatiable demand for SUVs and pickup trucks. Low gas prices have led to a boom in SUV sales, while sales of more efficient models have remained stagnant. Most of those SUVs get better fuel economy than the gas guzzlers of a decade ago, but they still drag down fleet averages, because those averages are sales weighted.

Officials now say the 54.5-mpg target was never a mandate, but rather an estimate of where the industry could be in 2025. That estimate was based on the assumption that 67 percent of the market would be cars and 33 percent would be SUVs, pickups, and other light trucks. New estimates assume a more even split between car and truck sales.

Accounting for greater SUV sales, regulators believe average fuel economy will hit 50 to 52.6 mpg by 2025. The change likely has carmakers popping champagne, but environmental groups probably won’t be happy. The EPA will make a final decision on adjusting fuel-economy targets for model years 2022 to 2025 by April 1, 2018.

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.
