The 2018 Audi A8 comes with interesting technology that enables the driver to save on fuel. This is particularly a laudable feature, especially to those who are considered practical. Audi is a luxury brand, however, its owners still care about fuel economy. It also adds its green appeal as well.

The 2018 A8 has a standard, which consists of water-cooled 48-volt alternator starter. This is mounted on the front side of the engine and complementing the regular pinion starter. Such only works during cold starts. It also has a lithium-ion battery pack in the trunk with 10-Ah capacity and 48-volt system.

The sedan is equipped with an advanced coasting function available from 34.2 to 99.4 mph once the driver takes his foot off the accelerator. At this speed, the engine automatically turns off. This is to ultimately save fuel. It will be in this mode for about 40 seconds.

As the driver steps on the gas pedal again, the combustion engine activates without acceleration delay. This happens because of the 48-volt system which is permanently connected to the engine.

The 2018 Audi A8 also has a stop/start function, which is considerably different from other systems currently available. Its predictive starting system enables the A8 to move when the car in front starts to be in motion. This is possible even when the driver is still stepping on the brakes.

The A8 energy recuperation happens not only when it is coasting but also as the car slows down if its gets close to the vehicle in front of it. Because of this, it reduces fuel consumption by 0.7 l/100 km. This is definitely significant that industry experts look forward to.

The 2018 Audi A8 is scheduled to be unveiled on July 11 at the Audi Summit event. This is going to be held in Barcelona, Spain. Next month marks a momentous event for Audi as it continues to mesmerize everyone with its exceptional automotive technology.
