The i8’s drivetrain combines a three-cylinder gasoline engine, powering the rear wheels, with a front-mounted electric motor powering the front wheels. As you’d suspect, that makes the amount of power sent to both front and rear wheel highly variable, allowing the i8 to optimize power based on available traction.
The three-cylinder gasoline engine used in the i8 will produce roughly 223 of the car’s combined 354 horsepower, and now comes word from Whatcar that these triples will be built in BMW’s Hams Hall factory, near Birmingham, England.
While that’s good news for BMW’s U.K. workers, the niche market i8 hybrid sports coupe isn’t likely to see volume production. Ensuring that the engine assembly line is kept busy, expect to see the same three-cylinder engines make their way into future BMW 3 Series models as well.
Will consumers embrace further downsizing of the 3 Series engine range? The move from six-cylinder to four-cylinder engines hasn’t hurt 3 Series sales one bit, so we’ll guess that the answer is “yes.” As long as consumers are happy with how a car performs, most won’t bother to count the number of cylinders beneath the hood.
