BMW M4 MotoGP Safety Car gets tangible boost in performance with water injection
BMW introduces innovative water injection technology for the 2015 MotoGP season in the M4 coupe. The 2015 BMW M4 MotoGP Safety car made its premiere at the World Championship in Qatar this past weekend. The BMW M4 is just one of a fleet of six vehicles that the German automaker employs as Safety Cars. BMW says it get more power than the production M4.
The 2015 BMW M4 MotoGP Safety car gets special water injection technology that sets the coupe apart from the other BMW safety vehicles. BMW is pushing the limits of engine technology and the new M4 MotoGP Safety Car gets this new technology that its been testing. Water injection for turbocharged/supercharged engines isn’t new, as its been around for decades.
Instead of injecting a mixture of fuel into the combustion chamber, it injects water into the combustion chamber, something that wouldn't usually be recommended because so many things can go south. If the mixture of water is too low or too high, it won’t work and the engine is ruined.
Water injection gives a "tangible boost" in performance
BMW says they’ve perfected the technology and it gives the production engine of the M4 (with 431 bhp/317 kW), “a tangible boost in performance.” They don’t disclose exactly how much power the water injected powerplant produces. Check out the video that shows this technology in the 4.0-liter M4 engine.
The system is designed to cool the mixture of fuel and air that become extremely hot inside the engine environment. The system injects a fine mist of water into the collector that reduces the air's temperature to a more optimal temperature, helping the combustion process. BMW says there a number of benefits that include reducing the need for higher octane fuels, controlling the adverse effects of higher ambient temperatures and most importantly, it increases power output and reduces fuel consumption by around eight percent.

The new water injection technology lives under the hood of the matte black wrapped 2015 BMW M4 MotoGP Safety Car with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and all the emergency equipment.
Along with the M4 MotoGP Safety car, BMW employs five other safety cars at MotoGP that include the BMW M3 and BMW M6 Gran Coupe, BMW M5, while the new BMW X5 M and the BMW M550d xDrive Touring are used as medical cars. BMW Motorrad also provides two BMW S 1000 RRs as safety bikes. BMW says the new technology and software needed to make the water injection technology in the 2015 BMW M4 actually work, is here now and it will become reality in future production BMWs. Stay tuned.
