Mazda’s Diesel CX-70 Pushes Past 800 Miles Per Tank - Too Bad It’s Not Coming to the U.S.

Diesel engines are practically extinct in passenger cars these days. Most automakers have dropped them entirely in favor of hybrids and EVs, leaving diesel mostly to big trucks. But Mazda isn’t following the herd. Its new CX-70 SUV, introduced for the 2025 model year, offers a turbocharged inline-six diesel in select markets, and the numbers are hard to ignore.

3-liter diesel with a mild hybrid system, producing 251 horsepower and 406 lb-ft of torque. That’s enough to hit 60 mph in about seven seconds and, more importantly, deliver roughly 44 mpg. 5-gallon tank, Mazda says the CX-70 diesel can theoretically travel up to 850 miles on a single fill-up.

Some early reports even suggest 870 miles is possible under ideal conditions. That kind of range is almost unheard of in a modern crossover.

There’s a catch, though: American buyers won’t get this version. The diesel CX-70 is reserved for Australia, New Zealand, and parts of Asia. S. 5-liter four-cylinder hybrid. Mazda has no plans to bring a diesel hybrid to North America, a decision shaped by strict emissions rules, the lingering stigma from the 2015 Dieselgate scandal, and a market that has largely moved on to gas-electric hybrids and EVs.

Even without the diesel, the CX-70 is a well-rounded package. It shares its platform with the CX-90 but drops the third row, freeing up 40 cubic feet of cargo space (75 with seats folded). The cabin features leather upholstery as standard, with a red leather option that’s exclusive to this model.
