ABT Sportsline has also just revealed a single teaser like photo with their ABT Volkswagen Golf R that will debut in Geneva this week along with the ABT Audi R8 Spyder and the ABT AS8 Audi A8.
Due to revised engine electronics, the ABT Volkswagen Golf R and its 2.0-litre TSI engine will pack 310 horsepower (228 kW) which means 40 horsepower more than the stock version, and improved performance figures indicate accelerating to 100 from a standstill will now take 5.2 seconds. The ABT Volkswagen Golf R can also reach a higher top speed of 261 Km/h.
Individualisation parts added on the ABT Volkswagen Golf R include a new front spoiler with incorporated LEDs and fog lights, custom rims wrapped in performance tires and even though the tuner did not mention, we suspect new side skirts, a sportier rear apron, new exhaust pipes and possibly a new suspension.
ABT press release :
When ABT Sportsline deals with the VW Golf, the result is traditionally a compact super sports car. This is because the world’s largest tuner of vehicles from the Volkswagen group has given all generations of the successful Wolfsburg car an optical and technical boost. The current super Golf answers to the letter R, which announces the most important characteristics of the car: the "R" stands for "racing" – it transports the experience of ABT, which has recently defended its DTM title and won the ADAC GT Masters. Instead of the series-standard 270HP (199 kW) the engine now offers a dynamic 310HP (228 kW). With a high-speed of 261 km/h the ABT R is especially fast – and it is also capable of quick acceleration: it sprints from a standstill to a speed of 100 km/h in 5.2 seconds.
“The compact car is really good fun, particularly on corners”, states Hans-Juergen Abt. For the General Manager of ABT Sportsline each Golf is a challenge which he and his team are happy to confront: “VW gave the Golf dynamism when it was in the cradle – it defines sportiness in its class. And the Golf R is the champion of fast Golfs.” Optically, some interesting details provide the vehicle with a particularly self-confident appearance: the ABT Daytime running lights, front apron and front lip make the Bavarian car seem even more powerful and perfectly harmonise with the new CR alloy. The especially light design wheel looks exceptional on the ABT Golf R, particularly in 19 inch. Fitting high-performance tyres are, of course, also available, meaning that nothing stands in the way of the especially agile shape of the Golf sport. The newcomer to the Golf family is, of course, absolutely suitable for everyday driving and is good-natured and not touchy in heavy traffic. But look out when it let’s loose…
