Audi A4 g-tron and A4 Ultra Are All About Economy in Frankfurt

The new Audi A4 is still as fresh as the Prince of Bel-Air, but Audi had to bring something absolutely new at the Frankfurt Motor Show to share the stand with the e-tron.

These novelties came in the shape of two Audi A4 models with special engine features, both aimed one way or another at reducing fuel consumption and, even more so, fuel costs for the car's user. It's all about the gas
The g-tron is basically a petrol powered Audi A4 that can switch between fuel types from the classic stuff to CNG (compressed natural gas). While this doesn't necessarily reduce fuel consumption per se, the CNG is considered a by-product of the oil refining process so it's cheaper and just as efficient. The switch will occur automatically when the CNG tank is depleted, but can be triggered manually by the push of a button.

This isn't new for Audi, as an A3 Sportback g-tron already exists. That car uses a 1.4 TFSI engine developing 110hp, which is 12hp less than the regular 1.4 TFSI A3. Some minor engine modifications are also in order, so the end result is a car that's more fuel efficient and less dynamically potent. We don't yet know what figures the engine in the A4 will produce, but expect them to be slightly above those of the A3 Sportback g-tron.Ultra is not what you might think
The Audi A4 Ultra, on the other hand, is a more conventional concoction. The Ultra moniker is used to mark Audi's most fuel efficient conventionally powered vehicles, so if you were expecting something else, we're sorry, we really are.

On the new Audi A4, the Ultra models use 2.0-liter engines burning either petrol or diesel fuel. The TDI engine is tuned in such a way it brings fuel consumption down by 21 percent compared with the regular version. It needs just 3.7 liters to cover 100 kilometers, or one gallon for 63.6 miles. Its CO2 output is 95g per kilometer or 152.9g per mile.

The petrol TSI version offers equally impressive numbers, starting with the engine's power output: 190hp. Fuel consumption is surprisingly low for at 4.8 l/100 km or 49mpg, with CO2 emissions of 109g/km or 175.4g/mi.

So, whether you're very eco-conscious or just plain cheap, the new Audi A4 will have multiple options for you to choose from.
