BMW F82 M4 GTS

Water injection, a titanium exhaust, carbon everything and a 7:28 Nürburgring lap. The most extreme S55 BMW built.

BMW F82 M4 GTS — 2016

The GTS is the F82 taken to its limit: water injection to cool the charge air and allow more boost, a titanium exhaust, carbon fibre bonnet, roof and driveshaft, manually adjustable coilovers, a rear roll cage and Michelin Cup 2 tires as standard.

Just 700 were built worldwide, 300 for the United States. It is a track car with plates — stiff, loud, and stripped, with orange accents that make it instantly identifiable.

Ownership is niche. The water injection system needs its tank filled and its pump cared for, and the car is genuinely uncomfortable on bad roads. As an investment and as a track weapon, it works.

Year by year

  • 2016 — single model year

    700 cars total. DCT only. Frozen Dark Grey Metallic with Acid Orange accents; carbon fibre bonnet, roof, splitter and diffuser.

The good and the bad

Positives

  • +Water injection genuinely works and makes the S55 feel unburstable
  • +Titanium exhaust with the best sound of any S55 car
  • +Manually adjustable coilovers and a serious aero package
  • +Only 700 built — collector status is secure
  • +Devastating on track straight out of the box

Negatives

  • −Punishing ride and heavy road noise
  • −Water injection tank requires regular refilling with distilled water
  • −DCT only; no manual option
  • −Cup 2 tires are unsuitable in cold or wet conditions
  • −Very expensive to repair cosmetically — carbon panels are model-specific

Known faults and what they cost

  • Water injection pump and tank$800–$2,500

    Neglected systems corrode; the car reduces power if the system faults.

  • Crank hub$4,000–$6,000

    Same S55 concern with higher cylinder pressures. Most owners pin preventively.

  • Cup 2 tire ageing$1,800–$2,600 per set

    Low-mileage cars often carry dangerously old rubber.

  • Carbon panel damage$5,000+ per panel

    The bonnet, splitter and diffuser are GTS-specific and scarce.

Pre-purchase inspection checklist

  • 01Confirm the water injection system is functional and the tank has been maintained
  • 02Verify build number and full BMW service history
  • 03Inspect carbon aero for stone chips, cracks and repairs
  • 04Check tire manufacture dates regardless of tread depth
  • 05Confirm whether the car has been tracked and to what extent
  • 06Scan for boost and water-injection related fault codes

Modifications for longevity

  • Water injection care

    Distilled water only, keep the tank topped, exercise the system regularly.

  • Crank hub pinning

    Standard preventive work on any GTS being used hard.

  • Cooling and oil

    Track use demands short oil intervals and a healthy cooling stack.

  • Storage discipline

    Battery tender, dry storage, tire pressures maintained to prevent flat-spotting.

  • Carbon protection

    Paint protection film on the splitter and bonnet leading edge.

Modifications for performance

  1. 01Leave the hardware alone

    Originality drives value on a 700-car run.

  2. 02Tires and alignment

    Fresh Cup 2s and a track alignment; the coilovers are already adjustable.

  3. 03Tune

    530–560 hp is achievable, but weigh it against collector value and warranty.

  4. 04Track prep

    High-temp fluid, brake ducting and a proper cool-down routine matter more than power.

What they are worth

GTS values held above original MSRP for most of their life and remain firm. Mileage, colour of accents (all the same) and documentation of track use are the main variables.

US cars are the scarcest; a low-mileage, never-tracked example with full history sits at the top of the market.
