Mitsubishi is set to introduce its updated 2019 Outlander PHEV in Geneva next month. The automaker has given its plug-in hybrid version of the SUV – which made its debut in Paris back in 2012 – a number of revisions, with a redesign of its powertrain leading the changes.

The range extender will now come with a 2.4 litre Atkinson cycle petrol engine, which replaces the previous Otto cycle 2.0 litre as the generator mill, and this promises higher torque output and smoother operation, among other things.

Capacity of the lithium-ion battery has also been upped to 13.8 kWh (previously, 12 kWh), and this continues to drive the two independent electric motors on both the front and rear axle.

No specific output numbers are touted for the engine and the motors, but output has been bumped up for the generator and rear motor by 10%. On the current car, the two permanent magnet synchronous motors each offer a 60 kW output, so the rear unit should be putting out around 66 kWh, going by the math.

Torque figures should also go up, definitely for the rear motor – currently, the front motor delivers 137 Nm while the rear unit offers 195 Nm. Elsewhere, the SUV’s 4WD system also gets two additional driving modes, with Sport and Snow modes joining the existing Normal and 4WD Lock modes.

Aside from mechanical changes, the Outlander PHEV also gets tweaks to its exterior design as well as a minor overhaul for its interior. External changes are made up of a new front grille design, LED headlamps, rectangular fog lamp bezels as well as a new front skid plate. The SUV also gets a larger rear spoiler and new two-tone design, multi-spoke 18-inch alloy wheels.

Inside, the cabin is now dressed in new quilted fine leather upholstery, and fresh bits include new hip-hugging front seats and a restyled instrument panel. The car also gets revised switchgear and new trim, along with rear air-conditioning vents.
