BMW M4 GTS launched and its slick!!

The M Division is well know for transforming the normal family cars from BMW in track ready cars which not only drive better but that are also more powerful as well as better driver’s cars. The stock M4 is already one hell of a car but the performance version of a performance car is something unbelievable.The company has made an even faster one, BMW M4 GTS. Only 700 examples will be built of this ultra fast machine.

It is the first instance of water-injection system making presence felt on a road legal car. Power comes from the M4’s familiar turbocharged 3.0-liter straight-six, however, the engine has been upgraded with a new water injection system that not only boosts power but also improves efficiency. It’s got 493 horsepower, 527Nm of torque, a three-way adjustable coilover suspension, and a weight reduction of roughly 200 pounds compared to a stock M4.

How fast will it go? BMW quotes a blistering 0-100 kph time of just 3.7 seconds. Top speed is a tick under 300kmph and a lap of the Nurburgring takes just under seven and a half minute.

What is the water injection system? Basically, water absorbs heat from surrounding air, so a fine mist is sprayed into the intake manifold where it evaporates, lowering the temperature of the intake air. BMW says this reduces final compression temperature, allowing the turbochargers to operate with increased boost pressure and better spark timing.

Do we have to top up the water?  A 5 litre tank is located below the trunk and is joined by the water pump, sensors and valves. BMW concedes that under track conditions, this tank might have to be topped up with water every time the vehicle is refueled. However, under normal everyday operating conditions, the intervals are said to be much longer. Even in highway driving, the water tank only needs topping up at every fifth refueling interval. Systems are in place to ensure the engine is protected should the tank run dry.

Where did the weight reduction come from? Carbon fiber reinforced plastic (CFRP) is used in the bonnet, making that part some 25 percent lighter than the stock piece. CFRP is also used for the driveshaft, making it 40-percent lighter than the standard setup.

How much would it cost? Pricing will be disclosed at the upcoming Los Angeles Motor Show in November.
