2015 BMW 3 Series | spy shots

Carsguide’s spy photographers captured a prototype of the new model testing ahead of its expected 2015 showroom debut. In response to the new generation Mercedes C-Class – which has moved more upmarket with cues and technology from the flagship S-Class -- the 3 LCI (Life Cycle Impulse in BMW speak) will bring refreshed styling and updated technology to the Bimmer.

The changes aim to keep the popular model competitive against its newer rivals. However, in typical BMW-fashion the facelift is of the ‘blink and you’ll miss it’ variety, with exterior styling revisions limited to just the front bumper. New lower air vents are expected to give a more modern appearance while full LED headlamps replace the bi-xenons offered on existing 3 Series models.

More significant changes have been made beneath the metal with the 1.5-litre three-cylinder petrol and diesel engines from the new Mini becoming available in the 3 Series. The petrol version produces 100kW and 220Nm in the iconic little British hatchback, while the diesel makes 85kW, however these engines will likely receive small power bumps for their application in the larger BMW product.

The updated 3 Series will also receive a host of new driver assistance technologies. These include BMW’s traffic jam assistance program which first debuted in the 5 Series. Using a forward facing camera this program automatically controls the brakes, throttle and steering at speeds of up to 40km/h, allowing the driver to relax during heavy traffic. The new BMW 3 Series is expected to debut before the end of this year, and reach our shores in 2015.
