BMW diesel engines could make its way into the next-generation Toyota Corolla, according to an article by Indianautosblog, citing various Japanese reports. This is likely a continuation of the partnership between the two companies, which was first signed back in 2011.

Even so, the new Corolla won’t be the first to use BMW-supplied diesel engines, as the Verso is the model to claim that honour. More recently, the Avensis facelift also gained the BMW-derived oil burners, available in 1.6 litre D4-D and 2.0 litre D4-D guises.

Details about what will be fitted on the all-new Corolla remain a mystery for now, including the type of diesel engine(s), but it is suggested that only higher-spec variants will benefit from them. Likely engines include the B37 1.5 litre three-cylinder and B47 2.0 litre four-cylinder.

The Corolla will most likely ride on the Toyota New Global Architecture (TNGA), first used on the fourth-generation Prius, allowing it access to the 8NR-FTS 1.2 litre turbo four-cylinder, 2.0 litre Dual VVT-i four-cylinder and 1.8 litre VVT-i Atkinson cycle four-cylinder engines, all featured on the C-HR crossover.

The BMW-Toyota partnership is not limited to just engine sharing, but also the joint development of sports cars and lithium-air batteries, where the former involves a new Supra and Z5.
