Designed to appeal to buyers in China and the United States, the model could be based on either the rear-wheel drive platform that underpins the 1-Series or the front-wheel drive UKL platform that will debut on the 1-Series GT. The company is reportedly considering both platforms because each has their own advantages - notably cost, packaging and handling.
While there's still a lot of uncertainty about the model, the 1-Series sedan has reportedly been fast-tracked for a 2015 launch. Sources have indicated the model is such a high priority that BMW may have contacted suppliers which could help develop or produce the vehicle.
Engine options will likely carryover from the standard 1-Series, but the M variant is rumored to adopt a turbocharged 2.0-liter engine that develops more than 300 HP (221 kW).
