The largest gathering of Volkswagen and Audi cars in Europe is underway, and the German premium carmaker is displaying the third model of its G-Tron range at the 2017 Worthersee Meeting wrapped in special finish and with apparent aesthetic tweaks.
Audi unveiled the production version of the new Audi A5 Sportback G-Tron at the 2017 Geneva Motor Show in March. Before the model’s eventual introduction to the market in early summer, Audi is making sure that the new G-Tron car gains more attention from the public by showcasing a one-off variant at the Worthersee Meeting.
The A5 Sportback G-Tron at Worthersee sports a customized two-tone exterior to make it more appealing. However, it isn’t a fully modified unit, unlike the VW GTI First Decade concept that is also being displayed at the event. Around two-thirds – starting from the front end -- of the exterior of this one-off A5 Sportback G-Tron is wrapped in dark grey finish. It then blends with a honeycomb blue finish on the rear side doors. This finish completely dominates the rear end of the one-off A5 Sportback G-Tron.
This Worthersee display also features blue accents that are present in the headlights. It comes with two-tone alloy wheels, blue calipers black rear spoiler as well as tinted rear lighting units. “G-Tron” badging is found on the front doors and above the rear window. The interior of the Audi A5 Sportback G-Tron features Alcantara seats as complemented by blue stitching and carbon fiber trim. “G-Tron” badging is found on the front seats.
Audi’s G-Tron models are actually powered by conventional engines that run on gasoline (petrol) but that are also capable of running on CNG (compressed natural gas). The upcoming A5 Sportback G-Tron follows the G-Tron versions of the A3 Sportback and the A4 Avant. The A5 G-tron is powered by a 2.0 TFSI engine that delivers 125 kW (170 hp) of output and 270 Nm (199.1 lb.-ft.) of torque.
What makes G-Tron models appealing is that they boast of greater fuel efficiency than their conventional counterparts. For instance, a gasoline-powered A5 Sportback with S tronic consumes 5.6 liters of fuel and emits 126 grams of carbon dioxide per kilometer. On the other hand, the Audi A5 Sportback G-Tron with S tronic consumes just 3.8 kilograms of gas per 100 kilometers and emits 102 grams of carbon dioxide per km.
In the NEDC cycle, the A5 Sportback G-Tron could travel up to 500 kilometers (310.7 miles) using just CNG. As soon as the pressure in the tank drops below 10 bar – signifying around 0.6 kilograms (1.3 lb) of CNG remaining, the engine management seamlessly switches to gasoline power, which extends the range of the A5 Sportback G-Tron by 450 kilometers (279.6 miles).
