Spy shot BMW 3 Series

Two years ahead of its showroom appearance, the all-new 3 is caught for the first time outside BMW's development base at Munich in Germany.  The hand-built prototype carries heavy camouflage in the company's signature swirls, but it is still easy to pick the general shape and proportions of BMW's future best seller.

The next 3 Series, coded E93, will be slightly bigger and much more elegant than the current E90. It picks up the styling direction of the latest 7 Series flagship, which has been smoothed and preened from the brutalism of the previous Seven.

The upcoming E93 has typical 3 Series proportions, from its wheels-at-each-corner chassis layout to a short rear overhang and the C-pillar treatment with what BMW calls its 'Hofmeister kick'. 

Carparazzi pictures of the car show a widened grille and the same sort of headlamp treatment already seen on the Seven and expected on the upcoming 5 Series replacement, which will be on Australian roads in June 2010. At the back, the boot and light treatment is typically BMW with an L-shape to the lighting package.

BMW insiders say the the plan for the next 3 Series will again see the coupe and cabrio models take a slightly different design direction from the sedan and wagon. The shift will include unique lamp packages with more body jewellery for the upmarket models.

Like the 1 Series, the E93 has a flexible, modular mechanical platform which allows BMW to spin extra models with minimal time and cost penalties.

The model lineup for the new 3 Series is still not clear, but is expected to include an active hybrid with a three-cylinder engine connected to an electric powerpack, with everything from special tyres to aero-tweaked wheels, brake-energy regeneration, engine stop-start system and a pre-heater for the engine, gearbox and differential to cut emissions through the critical first few minutes of any trip.
