Video: 730-PS BMW M140i tested on the dyno

Few would argue that the new BMW F40 M135i is a near-complete downgrade from its predecessor, the good old F20 M140i. Fewer cylinders, less power and no rear-wheel drive at all – what’s to be proud about? No wonder that is the older generation that got tuned to 730 PS (720 hp / 537 kW) earlier this week.

Few would argue that the new BMW F40 M135i is a near-complete downgrade from its predecessor, the good old F20 M140i. Fewer cylinders, less power and no rear-wheel drive at all – what’s to be proud about? No wonder that is the older generation that got tuned to 730 PS (720 hp / 537 kW) earlier this week.

The owner of the hot hatch does not reveal all the details, but we are told that the block is all that remains of the original engine. The rest is new, including a more powerful turbocharger, special downpipes, a methanol injection system, and a high-flow air intake system. An ECU update is also present.

When it was put on the dyno (see video), the car was able to produce 730 PS along with 950 Nm (701 lb-ft) of peak torque. Its owner has further plans to increase induction pressure and use racing-grade gas, which should result in a boost to around 850 PS (838 hp / 625 kW).
