We caught the latest 3 Series Estate, known at BMW as F31, in European cold-weather testing. The Estate model will grow in all dimensions, which means more interior space for the passengers and their luggage. It will also become a bit more flexible than its predecessor: all 3 Series Estates will most likely have 40/20/40 flat-folding rear seats, a boot cover that retracts and lowers with the boot lid and rear window that will open separately to aid practicality. BMW will also give the next 3 Series the very latest in efficient dynamics technologies - there will be an active hybrid model using a threecylinder engine connected to an electric motor as well as low-resistance tyres, aerodynamically designed alloy wheels, BMW's active aerodynamics, solar roof panel, brake energy regeneration, stop-start and pre-heating technology for the engine, gearbox and differential. It's highly unlikely we'll see it in the UAE, though.
