Audi's hot new SQ8 has made its Frankfurt debut as the firm's flagship SUV, featuring a 429bhp mild hybrid turbodiesel V8 engine.
The 4.0-litre biturbo unit offered in the range-topping performance version of the coupe-inspired Audi Q8 large SUV is the most powerful V8 offered by the firm in Europe. It produces 664lb ft and powers the five-seater from 0-62mph in 4.8 seconds, with a limited top speed of 155mph.
All the news from the Frankfurt motor show
The diesel, which automatically turns off one of the two turbochargers at low speeds to boost fuel economy, is mated to a 48V mild hybrid system, operated through a belt alternator starter connected to the crankshaft. It can generate up to 11bhp under braking, and allow the SQ8 to coast without the engine active for up to 40 seconds at speeds between 34 and 100mph.
Power is driven to all four wheels via an eight-speed automatic gearbox, with an optional advanced suspension package including a sport differential that can balance torque between the rear wheels when cornering.
As standard, the car sits on adaptive air suspension, which can adjust the ride height by up to 90mm, and features electromechanical active roll stabilisation, which uses an electric motor to reduce body movement.
All-wheel steering is available as an option, either by itself or as part of the advanced suspension package.
The SQ8 sits on 21-inch wheels as standard, with 22-inch available upon request. Carbon fibre ceramic brake discs are available as standard.

"Most Powerful V8"...?
But what about the 444bhp RS4?!
Last time I checked the RS4
Last time I checked the RS4 wasn't a Diesel??
Agree, looks like the Urus,back view in particular
The Urus should have had the v10 to differentiate it for the large bucks that it commands,do not mind the Q8 ,the grille is overdone like most Audi's , but the Q8 is the least ugly of the BMW and Audi suv ranges ,the Q5 ,Q7 X3,X4,X5 and X7 should be used for target practice by the military.
Meanwhile in other news
its a diesel.. Now if if it was a petrol V8, it might be of interest..
