The C-HR’s engine, a punchy 2.0-liter four-cylinder dual-overhead cam producing 144 horsepower at 6,100 rpm and 139 pound-feet of torque at 3,900 rpm, sends all power to the front wheels via the Continuously Variable Transmission with intelligence and Shift mode (CVTi-S). The engine employs many of Toyota’s latest generation of technologies, including Variable Valve Timing (VVT) and Valvematic, both of which have received extensive optimization to enhance fuel economy and smooth operation.
Valvematic offers a broader range of continuously variable valve timing (lift and phasing) to provide optimal intake valve (not on exhaust side) operation relative to engine demands. Furthermore, to reduce exhaust emissions, the catalyst is warmed earlier during the engine’s ignition cycle. Both models are expected to receive EPA-estimates of 27 city/31 highway/29 combined miles-per-gallon.
The all-new the CVTi-S received much attention by engineers and utilizes redesigned pulleys to enhance acceleration and fuel economy; a new belt structure to reduce cabin noise; and a coaxial two-port oil pump system that allows for continuous oil pressure modifications in various driving conditions. A Preload Differential helps to distribute torque between the left and right wheels during low-speed operation to make for easier, composed driving.
Of course, drivers and passengers will welcome the powertrain’s well-sorted nature, but they’ll love Sport mode and the simulated 7-speed Sequential Shiftmatic. Engaging Sport mode via the MID increases the responsiveness of the throttle, quickens the CVT’s automatic artificial “step-up” shifts, and maintains high engine speed to enhance acceleration. The EPS’ feedback is weightier for a more confidence-inspiring feel. Pushing the gearshift over to the left while in Drive engages Sequential Shiftmatic, and lets drivers shift simulated gears at their convenience.
