The second-generation BMW M2 will have even stronger performance and more versatility than the well-received current model when it reaches UK showrooms by the end of 2022, according to insiders.
The new version of M division’s smallest model is based on the upcoming third-generation 2 Series Coupé, which has been comprehensively re-engineered with a revised line-up of longitudinally mounted engines, a new eight-speed automatic gearbox, an updated platform, a significantly stiffer body structure and more advanced electronic architecture.
The changes provide the new, G87-generation M2 with much closer engineering ties to other M models than today’s M2 has. M division insiders say this will enable the new M2 to offer a further step up in performance while helping it to retain a reputation for dynamic excellence through the sharing of key components.
An internal source told Autocar: “It’s more powerful, with greater torque, but sharper, too. It’s still puristic, a driver’s car, but with a broader spread of characteristics, a greater divide between comfort and sport, than what we’ve seen up to now.”
Central to the model-specific changes for the upcoming Porsche Cayman GTS rival is the arrival of BMW M’s S58 engine. The twin-turbocharged 3.0-litre six-cylinder unit was introduced on the X3 M and X4 M, and more recently deployed in the new M3 and M4. It will replace the existing M2’s long-running N55 unit, introduced in 2009, as well as the S55 engine used by the more potent M2 Competition and M2 CS.
Key elements of the S58 engine include a newly designed crankcase, a longer stroke, a reworked cylinder head and a more efficient induction system, which uses two mono-scroll turbochargers in place of the single turbocharger in the engine it replaces. As with the older S55 engine, it also gets a petrol particulate filter.
Autocar understands the new inline powerplant, which will be updated to meet Euro 7 emission regulations during the M2’s planned seven-year life cycle, will be offered in two states of tune in a move mirroring that of the new M3 and M4 – both with a 7200rpm redline – although only the higher-output Competition car is likely to be available in the UK.
