At the 2017 Geneva Motor Show the brand presented the potential of its new technologies in the form of the Audi Q8 sport concept show car. Its 48-volt electrical system integrates a further developed MHEV system as well as an electric-powered compressor (EPC).
Together the two components provide a new level of dynamics. The efficiency is also significantly increasing – at low speeds as in parking, the show car can even be driven electrically.
Electrical coasting, powerful boosting: Audi Q8 sport concept
The brand has demonstrated the great potential of MHEV systems with its Audi Q8 sport concept car, which made its debut at the 2017 Geneva Motor Show. Located between the crankshaft and transmission, the starter alternator outputs 20 kW and 170 Nm (125.4 lb-ft). During deceleration, the powerful MHEV system can recover a high measure of energy and feed it back into the lithium-ion battery. At low speeds, it can drive the sports SUV by itself. Boosting by the internal combustion engine, a 3.0 TFSI, affords a total of up to 700 Nm (516.3 lb-ft).
The 48-volt system of the Audi Q8 sport concept features an electric-powered compressor (EPC) in addition to the integrated starter alternator. It closes the turbo lag and allows for a large and powerful mono twin scroll turbo. With a system output of 350 kW (476 hp), the show car accelerates from zero to 100 km/h (62.1 mph) in 4.7 seconds, and presses ahead to a top speed of 275 km/h (170.9 mph). The MHEV system lowers fuel consumption of the concept car by approximately one liter per 100 kilometers (0.3 US gal per 62.1 mi).
Audi Q7 e-tron 3.0 TDI quattro (combined fuel consumption in l/100 km: 1.9 – 1.8* (123.8 – 130.7 US mpg); combined energy consumption in kWh/100 km: 19.0 – 18.1 2016 saw the debut of the Audi Q7 e-tron (combined fuel consumption in l/100 km: 1.9 – 1.8* (123.8 – 130.7 US mpg); combined energy consumption in kWh/100 km: 19.0 – 18.1*; combined CO2 emissions in g/km: 50 – 48* (80.5 – 77.2 g/mi))
The Audi Q5 HFC (Hybrid Fuel Cell) followed in 2009. Its fuel cell had an output of 90 kW and was supported by a compact lithium-ion battery. Later Audi models with fuel cell technology bear the moniker “h-tron,” with the “h” standing for the element hydrogen. The company is using these vehicles to demonstrate its mastery of fuel cell technology – precisely as one would expect from the brand: sporty, emotional, efficient and clean.
the Audi Q8*, produced in Bratislava. The Audi A7* and the Audi A6* from our German plant in Neckarsulm. The Audi A1*, which will be reborn here in Martorell. And also in 2018, you will experience the Audi e-tron* made in Brussels, which raises electric mobility to the next level. This is the starting point of a large product initiative. This Audi A8 stands for the journey of the Four Rings. A journey into the next decade and into a new era of our brand. And there is a lot more to come from Audi. Please stay tuned … to what we are going to unveil in Frankfurt in eight weeks’ time. These two letters – AI – and the idea behind them will be an omnipresent companion on our way into the new era. Thank you.
