These latest spy shots show a prototype with the least camouflage yet, revealing very similar proportions to the outgoing model although the wheelbase is slightly longer.
The engine lineup should mirror the offerings found in the sedan, with a range of four-cylinder and straight-six units coming in both diesel and gasoline flavors.
A regular six-speed manual will come as standard, with a brilliant eight-speed auto offered as an option. It’s unlikely that a hybrid version will be offered, at least in the near future.
Look out for the world debut of the new 2013 BMW 3-Series Touring later this year, with a European sales launch also slated for later in the year.
As mentioned, a U.S. launch remains uncertain as BMW may choose instead to bring over its all-new 3-Series Gran Turismo, which has also been spied testing recently. Just like the bigger 5-Series Gran Turismo, which essentially replaced the 5-Series Touring in the U.S., so too may the new 3-Series version.
