2018 Audi A4 avant G-tron Specs, Dimensions, Interior
2018 Audi A4 avant G-tron – n a few years, the Volkswagen Group has developed a complete range of CNG models, all with a perfectly integrated dual power supply. The Audi has already in the range the A3 G-Tron, now is the turn of the 2018 Audi A4 avant G-tron and the A5 sportback G-Tron, which share the mechanics, based on the two-liter turbo TFSI from 170 horsepower and 270 nm with direct injection of gasoline and indirect methane. To exploit the greater antidetonation power of natural gas the compression ratio was brought to 12.6:1; The fuel is stored in four cylinders of composite material with a capacity of 19 kg of gas and in a 25 litre gasoline tank placed at the rear, which ensure autonomy (detected in the NEDC homologation cycle) of 500 and 450 km respectively. The car, which is able to tow trailers up to 1,500 kg, is equipped with a six-speed manual gearbox, but in option there is the S-Tronic double clutch with seven gears.
Different twins. Apart from the identification plates, the 2018 Audi A4 avant G-tron is indistinguishable from the twins with gasoline or diesel and in the cockpit only one detail can reveal the true nature of this car: the double indicator of the fuel level, to the left that of methane (with green LEDs) and to the right of gasoline. It should be noted that, like the other natural gas models of the VW Group, the 2018 Audi A4 avant G-tron can only operate in petrol only when methane is depleted. I miss to say, the finishes are impeccable, proportionally better than those of the SQ5.

Homogeneous delivery. In the short test lap of this automobile, along the roads around Munich Airport, the perfect operation of the gas supply has emerged, with a homogeneous power supply and adequate performance: squeezing the two litres turbo, the 2018 Audi A4 Avant G-tron passes from zero to 100 km/h in 8.4 seconds (8.5 with the manual) and reaches 221 km/h (223 with six marches). In these situations, however, the engine becomes a bit romboso, while traveling with the lighter foot is very discreet. The additional weight of the gas cylinders gives a greater “consistency” to the car, but remains to be verified the effect on the stability of the rear. As is to be estimated the gas consumption: at the end of the test, with a mostly quiet guide, the computer on board indicated an average of 5.4 kg/100 km (the one approved is 3.8 kg/100 km).
