G21 BMW 3 Series Touring shown in patent drawings

The new G20 BMW 3 Series sedan was only unveiled last week, but we’ve already got a good look at the new G21 Touring wagon, thanks to a patent filed at Brazil’s National Institute of Industrial Property (INPI). The patent drawings, unearthed by motoring site Quatro Rodas, show the longroof’s design in full (Photoshop wizard Theophilus Chin has also rendered the rear based on the drawings, which you can see below).

Of course, the conversion from sedan to wagon has gifted the compact executive model with a stretched roofline, so that’s not really a surprise. What is a bit of a surprise is that the Hofmeister kink has now been elongated and now starts immediately after the rear door shutline – similar to the X3 SUV.

All the rest of the four-door’s styling cues are there, including the huge conjoined double kidney grille, Peugeot-style notched headlights, NACA duct-inspired Air Curtain inlets in the front bumper, prominent rear fender bulge and three-dimensional L-shaped tail lights – all as expected.

Also expected is the same range of turbocharged engines as the sedan, including a 2.0 litre four-cylinder petrol in the 184 hp/300 Nm 320i and 258 hp/400 Nm 330i, a similarly sized diesel in the 150 hp/320 Nm 318d and 190 hp/400 Nm 320d and a 265 hp/580 Nm 3.0 litre straight-six diesel in the 330d.

There will also likely be a 330e plug-in hybrid with 252 hp (or up to 292 hp with the new XtraBoost mode) and up to 60 km of all-electric range, as well as a range-topping M340i with a 374 hp/500 Nm 3.0 litre straight-six petrol. On the sedan, an eight-speed automatic transmission is offered across the range, with a six-speed manual only available on the 318d and 320d.
