Subaru’s new Impreza sedan has been revealed at the New York auto show bearing the brand’s new, sharper styling details.The design’s most pronounced feature is its steeply raked windscreen, enabled by the A-pillar base having moved 200mm forward.Overall, the car is a single milimetre shorter than the current model, yet has a 23mm longer wheelbase which should translate into to greater legroom for rear passengers.FLAT-FOUR FUEL FAIRYSubaru says a key design imperative of the new compact sedan was to reduce fuel consumption. Powered by a two-litre, unblown, flat-four engine capble of 108kW, the new Impreza claims to consume only 7.8 litres/100km – an improvement of nearly 30% over the 2.5-litre. Drive is to all four wheels (obviously) through either a five-speed manual transmission or Subaru’s CVT. Inside, the new Impreza is trimmed with new materials, has an improved multifunction display, steering wheel-mounted Bluetooth control and USB/iPod connectivity. There is a 6.1-inch touchscreen for the satnav, too. Amazingly, despite all its promises of refinement and contemporary design, Subaru has still chosen to equip the new Impreza with a girdle-operated parking brake instead of a flip-switch electronic unit.How the current Legacy can have a push-pull electronically actuated parking brake and the new Impreza not, remains packaging a mystery.
