You Can Do A 2,000 Mile Road Trip In A Range Extender EV, And We Have Receipts

Range anxiety is the number-one reason people hesitate on going electric — and the Leapmotor C10 REEV is built specifically to make that fear irrelevant. CarBuzz put the theory to the test with a 2,000-mile cross-country road trip, and the numbers that came back are hard to argue with.

1. It drives like an EV because it basically is one

The Leapmotor C10 REEV pairs a 212-hp electric motor with a 1.5-liter, four-cylinder gas engine — but that engine never actually touches the wheels. Its only job is to spin a generator and keep the 28.4-kWh battery topped up while you drive. The result: instant torque, smooth and quiet operation, and the driving feel of a normal EV, with only an occasional faint drone from the gas engine kicking in.

Bold takeaway: You get the driving character of a battery-electric vehicle without ever needing to plan your route around a charging network.

2. The claimed numbers actually held up

Leapmotor’s official specs sound almost too good: 42.7 mpg from the Atkinson-cycle gas engine, plus 90 miles of pure EV range from the battery, adding up to a claimed 603-mile combined range on a 13.2-gallon tank. CarBuzz’s testers were skeptical going in — automakers routinely inflate lab numbers — but after the first ~400-mile stretch at a steady 75 mph, real-world fuel economy came in at 36.7 mpg. Driving a bit more conservatively at 70 mph for the next 500-mile stint bumped that to 42.9 mpg, essentially matching Leapmotor’s claim.

Bold takeaway: Unlike a lot of manufacturer range claims, this one survived contact with an actual 2,000-mile road trip.

3. Zero range anxiety, the whole way

The entire point of a range-extender EV is removing the mental math that comes with battery-only road-tripping. On this trip, that promise played out exactly as advertised — no scouting charging stations, no timing stops around a charge curve, just pulling into any regular gas station along the route. The C10’s 14.6-inch touchscreen handles nearly everything else in the cabin (Leapmotor ditched almost all physical buttons), which took some adjustment, but the core drivetrain experience never wavered across the full trip.

Bold takeaway: A range-extender drivetrain solves the actual practical problem with long-distance EV travel — not by improving charging infrastructure, but by making it optional.

4. This technology is coming to the U.S., fast

Stellantis holds a 20% equity stake in Leapmotor, and the range-extender tech tested here is set to filter into Stellantis-badged vehicles. The Ram 1500 REV is already headed for U.S. dealers with a similar formula scaled way up — a 3.6-liter V6 generator, a 92.8-kWh battery, and two electric motors producing 647 hp, good for a claimed 690-mile range and a 4.5-second 0-60 time. Jeep’s Grand Wagoneer REV and Nissan’s own REEV lineup are reportedly not far behind, and Audi already proved the concept works at the extreme end by winning the grueling Dakar Rally with a range-extender race car, the RS Q e-tron.

Bold takeaway: The Leapmotor test isn’t just a curiosity from overseas — it’s a preview of a powertrain approach about to show up across multiple U.S. brands.
