Porsche 911 GT3 RS

Porsche 911 GT3 RS has got an incredible engine with no turbocharger with just 4-liter flat six, but you get a 500 horsepower.  It has a maximum of 9000 rpm. It can go 0-60 in just 3.3 Seconds. It has got a top speed of 193 mph. The rear wheels are driven through a seven-speed dual-clutch automatic or an optional six-speed manual transmission.
It has fattest back tires for a road car. It has scaffolding in the back for stiffness, carbon-fiber body panels for lightness. The roof is made of magnesium, so if you turn it over and there are sparks, there will be a blinding flash of light, and then you will be having a convertible.

With its carbon-fiber rear ironing board, larger front spoiler, front fender-top vents, and new rear underbody diffuser, the RS produces double the downforce at 124 mph of the already pretty downforce-y standard GT3. 
The vents over the front wheels on Porsche 911 GT3 RS double the amount of downforce over the front axle, balancing the mighty rear downforce of that massive rear wing.

The engine has more swept volume and lower-friction internals, and offers more revs, sharper response and increased outputs.
The biggest changes center on the chassis and aerodynamics, plus greater scrutiny applied to weight savings, as befits the RS moniker.  Stiffer springs (double the rate of the previous RS at the front end, 50 percent up at the rear) deliver sharper responses and increased feel, the trade-off being a slight loss of ride quality – a sacrifice Porsche believe RS buyers will be happy to make
Porsche 911 GT3 RS  can handle corner amazingly because it has got a four-wheel steering, the engine is sitting over the rear axle which gives an astonishing grip.

Porsche 911 GT3 RS has intake air booster which helps to increase up to 20 horsepower. 
The RS’s look is, er, extroverted. Low and wide and accented with exposed carbon fiber and various aero addenda, the thing is never going to be pretty. But it is purposeful in appearance, and RS cars have always been the outgoing sort, offered in eye-popping color combos.
