2012 BMW 1-Series first official photos and details leaked

The 2012 BMW 1-Series has leaked to the web, ahead of its unveiling at the Frankfurt Motor Show.

Looking more substantial than its predecessor, the model adopts a prominent front fascia that draws inspiration from the 5-Series GT and 7-Series. The rest of the car is an evolution of the previous model, but the overall design seems rather promising.

Since the car rides on a longer 2.69 meter (105.9 inch) wheelbase, the cabin is roomier and luggage capacity climbs by an additional 200 liters (7 cubic feet). Additional information is limited, but the interior has higher quality materials, an improved design, and a 6.5-inch (or optional 8.8-inch) iDrive display. Furthermore, option include a collision warning system, speed limit detection, and Internet connectivity.

Under the hood, a variety of engines will be available. The turbocharged 1.6-liter petrol will have outputs of 136 PS (100 kW / 134 hp), 170 PS (100 kW / 168 hp) and eventually 250 PS (184 kW / 247 hp). On the diesel side, there's a turbocharged 2.0-liter that develops 116 PS (85 kW / 114 hp), 143 PS (105 kW / 141 hp) and 184 PS (135 kW / 181 hp). Regardless of what powertrain is selected, it will be connected to a six-speed manual or an eight-speed automatic transmission.

As part of BMW's EfficientDynamics strategy, all models will come equipped with an engine start/stop system and regenerative brakes. This should enable the 1-Series to have an average fuel consumption that ranges from 4.3 to 5.8 liters per 100 kilometers (40.6 to 54.7 mpg US / 48.7 to 65.7 mpg UK).

The 2012 BMW 1-Series will go on sale later this fall, so stay tuned for additional information.
