BMW M2 F87 -Overview

Overview

BMW M2 F87 — Overview

The F87 is the first-generation BMW M2, unveiled in November 2015 and produced from October 2015 to 2021. Built on the F8x chassis shared with the M3/M4, the M2 was marketed as the most accessible M Car in the range.

The standard model used a tuned N55 single-turbo six-cylinder, while the later Competition and CS variants received the S55 twin-turbo engine from the M3/M4 — splitting this generation's mechanical identity into two distinct eras.

Market Intelligence

As a model that ended production in 2021, the F87 M2 is now a used-market icon — the N55 standard car is the most accessible, while the S55 Competition and CS are the most sought-after for their true M-engine character.

Thin-Data Summary

The F87's engine range divides into two distinct eras. The N55 3.0-litre single-turbo straight-six (standard M2, 2015–2018) is the more accessible and less temperamental option — 365–370 bhp, robust when maintained, and free from the S55's more extreme failure modes. It uses M3/M4-spec pistons, crankshaft bearings and cooling, making it a well-engineered evolution of BMW's proven N55 architecture. The S55 3.0-litre twin-turbo straight-six (Competition, 2018–2021, and CS, 2020–2021) delivers 405–450 bhp and is a true M-division powertrain — but it introduces additional complexity: rod bearing wear, crank hub spinning, and higher running costs. The M2 CS (2020–2021) is the ultimate F87, with 444–450 bhp and lighter construction, but it's a limited-edition collector's piece with premium running costs. If you're buying an F87, the N55 is the sensible, reliable choice; the S55 Competition is the performance sweet spot; the CS is for collectors.

Collector's Piece -rare and expensive

The F87 rule

A £6,000–£10,000 S55 recon against a £25,000 M2 Competition sits at 24–40% of the car's value -within our 70% BMW threshold. Against a well-kept £35,000+ example, the same recon drops to 17–29% -a repair decision, not a financial one. Against a sub-£20,000 high-mileage example, a major engine failure is borderline. On a CS, the calculus is different -the car's collector value justifies the S55's high replacement cost.

Key Takeaways

  • Which F87 Costs Least To Own?

    N55 standard M2 -simpler single-turbo design, fewer high-strain components.

  • Which F87 Costs Most To Own?

    S55 M2 Competition/CS -rod bearing and crank hub concerns add significant cost.

  • Which F87 Is Best Value?

    N55 standard M2 -the most accessible and reliable F87 variant.
