Audi now offers g-tron variants for the A4 Avant and A5 Sportback

It’s all in the name of cleaner alternatives

Audi already has the A3 Sportback g-tron out on the market but is now offering the same badge on the likes of A4 Avant and A5 Sportback.

Both models employ the same 2.0-liter TFSI unit that can run on either Audi e-gas, CNG (compressed natural gas) or gasoline.

The powerplant delivers 125 kW (170 hp) and 270 Nm (199 lb-ft) of twist. According to Audi's literature, the A4 and A5 fitted with this unit sport a maximum range of 950 kilos (590 miles). More than half of that – 500 km (310 miles) – can be covered relying solely on CNG.

Once the pressure in the CFRP gas tank drops below 10 bar, the engine automatically switches to gasoline. Each gas tank holds 19 kg of gas at a pressure of 200 bar.

On the performance side, Ingolstadt says the g-tron badge doesn't alter performance but don't expect Audi RS 5 levels of grunt. 

Therefore, the manual A5 Sportback g-tron needs 8.5 seconds to reach 100 km/h (62 mph) from a standstill – identical to the A4 g-tron – but has a higher top speed (226 km/h or 140 mph) than the A4 g-tron (223 km/h or 139 mph).

In Germany, the A4 Avant g-tron starts at €40,300, while the A5 Sportback g-tron requires a €40,800 investment.

Elsewhere, the carmaker will pay those who want to buy a new Audi as much as $10,000

Moreover, Volvo is also generous to potential XC90 T8 buyers, offering a $23,500 discount.
