To launch in global markets in 2018, reportedly.
According to several Japanese reports, BMW could supply engines for the next generation Toyota Corolla in 2018, as part of the BMW-Toyota technical partnership.
The Toyota engines rumoured to be offered on the new Corolla include a 1.5L 4-cyl petrol, 1.5L Hybrid, 8NR-FTS 1.2 turbocharged petrol and the familiar 1.8L VVT-i petrol engine. Expect the BMW-made engine to be offered in top variants, which could help boost the Corolla's appeal in the mass market, given BMW's prowess in engine development.
The next-gen Corolla will be based on the TNGA (Toyota New Global Architecture) from the new Prius, which is expected to offer a more responsive handling by increasing vehicle body rigidity, as well as better crash protection rating. Early test mules of the next gen Corolla appear seem to be barely bigger than the current model, although Toyota could increase its wheelbase, while keeping the length identical, for better rear seat occupant comfort.
As it's in the early stages of development, there are no concrete details on the next gen Corolla. Besides, Toyota is just starting to roll out the facelifted Toyota Corolla across key markets.
