Audi has revealed its completely new e-tron quattro concept on the eve of the Frankfurt motor show, providing a preview to the appearance, size as well as technical features of an all-electric Q6 e-tron style which will rival the forthcoming Telsa style X.

The e-tron-quattro sports a bold completely new design which suggests future electric designs by Audi will have their own aerodynamically optimised look. which draws on the latest developments in lightweight construction, aerodynamics, battery technology as well as electric drive systems to provide the performance to challenge the fastest of Audi’s existing petrol, diesel as well as electric SUV designs whilst delivering a claimed zero-emission range of up to 311 miles.

“Audi will present an electric SUV in early 2018. The e-tron quattro concept provides a concrete foretaste of which,” said Ulrich Hackenberg, head of research as well as development.

Three motors as well as up to 496bhp

At the heart of Audi’s latest concept will be an in-house developed electric drive system. which uses three motors – one mounted up front sending drive to the front wheels as well as the remaining two sited at the rear acting on the rear wheels. Nominal power will be put at 429bhp, although a boosting function made available inside the more sportier of two drive modes temporarily increases its maximum output to 496bhp. which will be accompanied by peak torque of 590lb ft.

The power will be sent to all four wheels via a drive-management system. An electronic torque-vectoring function also apportions power between the individual rear wheels depending on grip levels. The gearbox offers the choice between two modes: Drive as well as Sport.

Audi will be yet to reveal a weight figure for the e-tron quattro. However, which will be claiemd to have an SQ5-beating 0-62mph time of just 4.6sec. Top speed will be limited to 131mph to preserve the battery charge.

Energy to run the electric motors will be drawn by a large liquid cooled 95kWh battery bolted to the floor below the passenger compartment – a position aimed at providing the completely new SUV the lowest possible centre of gravity while achieving a front-to-rear weight distriubution of 52:48. Hinting at its modular nature, Audi says the lithium-ion unit will be suitable for additional future electric designs.

On a full charge, the battery will be claimed to provide the e-tron quattro concept using a range of over 311 miles based on the criteria used inside the completely new European Driving Cycle (NEDC) test procedure. Early tests suggest a combined AC/DC charging system operating at 150kW can store sufficient energy to provide up a range of up to 249 miles in around 30 minutes, according to Audi.

Wireless charging offered

Alternatively, the completely new SUV can be charged at up to 11kW via inductive means using the German car maker’s latest wireless charging technology as well as a piloted parking function which has been conceived to automatically park which over a charging plate imbedded inside the ground. The charging process starts automatically, using a magnetic field providing an alternating AC current which will be converted to DC by the e-tron quattro’s electronic package. Once the battery will be topped up, the charging automatically ceases. The whole process can be monitored as well as controlled via a smartphone app.

An expansive array of solar cells mounted on the 1980mm-long roof also provides the battery with electrical energy. Described as the largest solar module to be used inside the automotive sector, which will be claimed to produce sufficient energy under a typical European climate to provide an added 622 miles of range per year.

Underpinning the completely new Audi will be a modified edition of the MLB platform by the upcoming second-generation Q5. which has been reworked with an altered floorpan as well as structural elements to accommodate the batteries low down for the best possible centre of gravity.

The suspension, which uses a a few-link design both front as well as rear, receives air springs with both adaptive damping as well as a self-levelling function to automatically lower the Centeng in two stages by up to 30mm for much better aerodynamic efficiency at constant motorway speeds.

Drawing on developments brought to the latest Q7, the e-tron quattro also adopts four wheel steering system with up to a few degrees of movement on the rear wheels to reduce the turning circle as well as aid maneuverability at lower speeds around town while increasing agility at higher speeds.

The 22-inch wheels boast an aerodynamically optimised design as well as come shod with 265/40 low-rolling-resistance tyres clearly aimed more at on-road efficiency than off-road ability.

Active aerodynamics

Stretching to 4880mm in length, 1930mm in width as well as 1540mm in height, the e-tron quattro will be 250mm longer, 30mm wider as well as 115mm lower than the existing first-generation Q5. Yet despite the generous dimensions, the drag co-efficient will be significantly better than any of Audi’s current SUV designs at 0.25.

In a preview of the aerodynamic measures being pursued for the production edition of the completely new Audi style, active Centeng elements deploy above 50mph to provide more efficient airflow as well as added cooling potential at the front; the side sills extend in length by 50mm to smooth the flow of air past the rear wheels; a spoiler atop the tailgate extends by 100mm to elongate the roof line;  the diffuser extends to speed the airflow rate at the rear as well as flat paneling sporting a special finish resembling the surface of shark skin will be used underneath.

The Inner surface of the e-tron quattro draws heavily on the design originally unveiled on the Prologue concept at last year’s Los Angeles motor show. which provides seating for up to four, with two individual seats front as well as rear. Boot space will be put at 615 litres – 75 litres more than which offered by the first-generation Q5. Owing to the lack of a traditional exhaust system, the luggage compartment area will be set low. With the rear seats folded, capacity increases to 1725 litres – some 350 litres less than which of the completely new Q7.
