The third-generation Subaru Crosstrek, previously known to you and me as the XV, is now available as a hybrid in Japan. This may seem strange, given that the car was already offered in e-Boxer form, which has even gone on sale in export markets such as Singapore.
But that was a mild hybrid, whereas the new Crosstrek S:HEV uses a proper series-parallel system similar to that in the Toyota Prius. In fact, the entire “Strong Hybrid” setup has been lifted straight from Toyota as previously reported, except here it’s mated to Subaru’s trademark boxer engine and symmetrical all-wheel-drive system.
That boxer is a larger 2.5 litre naturally-aspirated flat-four (the e-Boxer uses a 2.0 litre mill) that alone makes more power than the entire e-Boxer system – 160 PS at 5,600 rpm and 209 Nm of torque from 4,000 to 4,400 rpm. This is allied to two electric motors, these being a motor-generator that charges the 1.1 kWh lithium-ion battery and a 88 PS/270 Nm traction motor that provides motive power.
The motors, eCVT setup, front differential gear and electronically-controlled coupling are integrated into a single transaxle, routing both petrol and electric power to all four wheels. The use of mechanical all-wheel drive sets the S:HEV apart from Toyota’s E-Four system for its hybrid models, which adds a separate electric motor to turn the rear wheels.
Subaru has not released any fuel consumption figures for the Crosstrek S:HEV, which is only slated to go on sale in December. It has, however, promised a total range of over 1,000 km on the WLTP cycle, thanks to the car’s relatively large 63 litre fuel tank. The car also comes with an optional vehicle-to-load (V2L) feature, outputting up to 1.5 kW through a power outlet in the boot.
To set the S:HEV model apart from the regular e-Boxer, Subaru has fitted the car with 18-inch shuriken-style alloy wheels and, on the top-spec Premium S:HEV EX, a new 12.3-inch digital instrument display. The EX variant also gets the enhanced EyeSight X suite of driver assistance systems, which enables hands-off semi-automated driving in traffic jams, lane change assist and speed control on curves and even at toll booths.
