2018 Audi A4 G-tron All Wheel Drive
2018 Audi A4 G-Tron Review – The standard joke when you gas and driving brings the theme: ‘ Gas is for cooking ‘. Well, that time has been, now that we have more and more electric cooking and current refueling. As an alternative to petrol and diesel is gas, as long and CNG, still an economical and clean option. The reason for the Audi A4 Avant and the A5 Sportback as g-tron, with an engine that has green gas or natural gas as fuel.
The Volkswagen Group has great plans when it comes to cng cars and want to be there to sell at least a million units by 2020. In addition, Audi us another glimpse into the future, by stating that two-thirds of the cars it builds in that year, an internal combustion engine and one-third will be all-electric. The plug-in hybrid sees Audi as a transitional phase to electric and from 2020 wants the brand from Ingolstadt more work on hydrogen. But today plays gas as the lead role. Audi even has its own gas plant built in Lower Saxony, Germany. From renewable energy, water, CO2, and organic rest material is there Audi e-gas produced and injected directly into the gas network.
Also in Netherlands is on reasonable scale green gas produced and that makes this fossil fuel free. That is also the reason why Audi no lpg version builds, all is there for those gas type a good branch network. The A3 g-tron we already knew and that car was briefly successful nice thanks to the low additional tax liability (14%). Now the 2018 Audi A4 G-Tron Review and the A5 Sportback g-tron added. These two have the same powertrain. The 2.0 TFSI engine delivers 170 horsepower and 270 Nm of torque, in the gasoline version is that 190 HP and 320 Nm. The valves and Pistons are adapted to the higher combustion temperature and compression is slightly raised, which is also made possible by the higher octane rating (130) of CNG.
2018 Audi A4 G-Tron Review Interior, Trunk
To a somewhat respectable amount of natural gas to be able to take them, there are no less than four tanks of different format under the floor. In terms of volume is equal to 120 liters, but you refuel cng in kg, representing a capacity of 19 kg. The tanks are made of, among others, with glass fiber reinforced polymers and polyamide. Non-metallic so and thus more than fifty percent lighter. The trunk floor is a few centimeters the filler neck omhooggekomen and sitting in front of the regular tank valve, in addition to those of the gasoline tank. The latter has a capacity of 25 litres. The gas comes via the intake manifold in the combustion areas and starts the engine on gas, unlike engines that have been converted to lpg. Only at temperatures below-11 or after there is tanked, the Audi is on petrol.
We drive in the A4 Avant G-Tron S-Tronic and may soon conclude that no punishment is to with a CNG car on the road. That, of course, has everything to do with the pleasant couple and the quiet course of the engine. And the incredible low engine speeds: at 130 km/h is that 2,100 rpm! In the manual version is that 2,500 rpm, still very neat. We drive on the German motorway without pace limit, so some extra gas. The 2018 Audi A4 G-Tron accelerates smoothly, but you notice that he bijterig is slightly less than the regular 2.0 TFSI or a 2.0 TDI. Nevertheless, he taps without too much trouble to 200 km/h.
2018 Audi A4 G-Tron Lower emissions, more MRB
After that short-lived sprint, we have the pace on 130 km/h taken not long after the highway exit. The rest of the test route takes over secondary roads through villages and towns so that we can form a reasonably good picture of consumption. We have to do in this case on the basis of the information that the onboard computer us.
On departure, we have that set to zero and at the end of the test drive, we denote 5.5 kg/100 km or a small range of 350 kilometers. In Netherlands to 400 also known as feasible, but much more is not in it. Now that’s also the case at an electric car, with the difference that’s out there a lot longer to fully charge again. The tanks of the 2018 Audi A4 G-Tron are filled within a few minutes, but you need to find a gas station first! In the Netherlands, there are around 150 and especially in the eastern part of the country are many blind spots. In Germany there are 900 stations and that number is raised to 2,000, because the Government understands that CNG is a clean fuel. Italy also has a very close tank network. In a not very distant past is there in the Hague signed a Covenant to driving on lpg and cng more attractive, but it is little.
In fact, it is absurd that the road tax for a car seen on a clean, nonfossil fuel as CNG is higher than that for the same car on gasoline. Along with the rather limited scope is that now even a threshold to switch because there is virtually nothing in further against driving on green gas.
