To say we were slightly disappointed to find out that the U.S.-Spec Toyota C-HR would only come with a 2.0L four-cylinder producing 144 horsepower would be an understatement. The European-spec C-HR has the choice of either a turbocharged 1.2L four or a hybrid, but neither of these powertrains will be showing up in the U.S.
Car and Driver spoke with the C-HR's chief engineer, Hiroyuki Koba to find out why. Koba didn't say why the turbocharged 1.2L would not come to the U.S., but we're guessing Toyota didn't want to put the effort in getting this engine certified for the U.S. Also, performance numbers between the 2.0L and turbo 1.2L are similar (11 seconds for the 2.0 to hit 60 mph, 11.1 seconds for the 1.2).
As for the hybrid, Koba said the decision comes down to the market, not engineering. At the moment, Toyota doesn't see the demand for this model in the U.S.
Koba did admit there is a possibility for a more powerful version of the C-HR, but quickly added there aren't plans for this at the moment.
