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.
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 BMW M2, which will be revealed next week, 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.”
This is something backed by Autocar's road test editor Matt Saunders, too, who described it as having "all the power and performance it needs and then some" after testing the prototype on track back in June.
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 BMW M3 and BMW 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.
