BMW’s latest lightweight track-ready limited edition, the 368kW/600Nm M4 GTS is set to arrive in Australia from this September.
Just 700 cars will be produced globally, of which 25 have been secured for Australian delivery with a starting price of $295,000 - but the sad news is the entire Australian allocation is already accounted for.
Those lucky enough to have secured this lightweight rarity will be treated to special weight-reducing features, like a carbon fibre reinforced plastic bonnet and roof, carbon fibre rear wing and front splitter, lightweight titanium exhaust, and high-performance carbon ceramic brakes.
The M4 GTS rolls on M alloy wheels, 19-inches up front and 20-inches in the rear, finished with unique Acid Orange highlights.
Recaro carbon bucket seats (50 percent lighter than the standard M4 seats) provide a suitable workbench for track work, while the rear seat has been deleted. The regular door trims have been stripped out and fitted with pull-straps.
All up the M4 GTS tips the scales 30 kilograms lighter than a regular M4 coupe.
The magic happens under the bonnet where the M4 GTS packs a reworked version of the regular M4’s 3.0 litre turbocharged inline six-cylinder engine, with outputs raised to 368kW at 6250rpm and 600Nm from 4000 to 5500rpm.
That’s a healthy upgrade compared to the standard M4’s 317kW and 550Nm and allows the seven-speed dual clutch equipped GTS to bolt from 0-100 km/h in 3.8 seconds, a reduction of 0.3 seconds next to the 'regular' M4.
To get those outputs, BMW has fitted the M4 GTS with a production-first water injection system, which draws from a five litre water tank (in the boot) and sprays water mist to the engine’s air-intake collector.
That in turn lowers combustion chamber temperatures by as much as 25 degrees Celsius, thus enabling higher boost pressure (up from 2.2 to 2.5 bar), earlier ignition, and more efficient combustion.
Underneath the car BMW has fitted a three-way mechanically adjustable coilover suspension system featuring independent control of damper rebound, high speed compression, and low speed compression. Ride height is also adjustable.
Aerodynamic upgrades include a manually adjustable front splitter, which in its track setting generates 105 Newtons of downforce at 200km/h. Likewise, the three-position rear spoiler is capable of 375 Newtons of downforce at 200 km/h in its track setting.
A no-cost Race Package is also available featuring a steel half roll-cage, fire extinguisher system, and six-point racing harnesses (with inertia reel seatbelts as well, to maintain road legality).
For those that want to take weight reduction even further M Carbon Compound wheels are also available, priced at $21,560.
Despite the aggressive race-ready package, the M4 GTS is road legal and can be registered in Australia - and for those game to use one as their daily drive will find features such as front and rear park sensors, satellite navigation, a head-up display, six-speaker audio system, and cruise control.
