Audi A3 Sportback g-tron

Geneva Motor Show starting the following week is a true competition between brands. Everyone tries to achieve high goals and to amaze the public. One of the news Audi is expected to present, is the A3 Sportback g-tron along with the e-tron plug-in hybrid variant.



Based on the five-door Audi A3 Sportback, this new car is equipped with a 110-hp 1.4-liter TFSI engine that produces 110 HP (81 kW) and 200 Nm (147 lb-ft) of torque, enough for a 0-62 mph (0-100 km/h) in 11 seconds and a top speed of 118 mph (190 km/h). Audi A3 g-tron has two tanks and a regular. It can burn both regular gasoline and compressed natural gas. The g-tron switches to gasoline operation automatically when the onboard CNG runs low, but the switch also can be triggered manually.



The g-tron possesses 12 horsepower less than the regular A3 1.4 TSI. To allow CNG operation, Audi worked on some changes in the turbocharger, cylinder head, injection system, and the catalytic converter. The two tanks, installed under the boot floor, can be filled with 7 kg (15.3 lbs) of CNG at a max pressure of 200 bar. The fuel consumption will be of 3.5 kg/ 100 km when using the gas and can be enough for 242 miles( 400 km). Both tanks are made from carbon fiber- reinforcement polymer. Each of them has a 27 kg( 59.5 lbs) weight when they are full.



The gasoline is supposed to be enough for driving 559 miles( 900 km), summing up a total range of 807.7 miles( 1300 km). That's a lot of distance between stops, and refueling is said to take just minutes- without taking into account the time spent hunting for a CNG station, for sure. The Audi A3 Sportback g-tron uses an electronic gas pressure regulator which can reduce the high pressure of the gas flowing from the cylinders. During low-speed driving it enables a low-pressure gas, but when greater performance is required it allows for a high-pressure flow.



As a response to more and more stringent CO2 emissions regulation, European carmakers are beginning to create vehicles fueled by compressed natural gas (CNG). The latest and possibly most advanced of these is the Audi A3 g-tron which becomes a friendlier car to the environment.
