A performance-focused Audi SQ8 was launched in June 2019. It features a new 4.0-litre Biturbo V8 mild-hybrid diesel engine with 429bhp and 900Nm (664 lb-ft) of torque (the US model will likely use the same engine as the current S6 and S7, a 2.9-litre Biturbo V6 mild-hybrid gasoline engine with slightly more power but significantly less torque), chassis revisions, and styling and technology upgrades. Performance is sent through the 8-speed Tiptronic automatic gearbox to its quattro all-wheel drive system. It has a claimed acceleration of 0-100 km/h in 4.8 seconds (0-60 mph in 4.6 seconds) with an electronically-limited top speed of 249 km/h (155 mph).

The new turbochargers are situated within the “V” of the engine block, which Audi claims creates better engine response. To further reduce the effects of turbo lag, the engine features sequential turbocharging, with only a small charger active at low engine speeds and a larger charger engaging above 2,200rpm. An electric-powered compressor assists the turbocharger when starting and accelerating from lower speeds, compensating for the turbo’s lack of boost at low revs by adding extra pressure to the intake to smooths out power delivery.

The compressor is also fed by the same 48V lithium-ion battery pack which supports the SQ8’s mild-hybrid system. Comprising a belt-driven alternator starter and regenerative brake system, it can power the SQ8 at speeds of up to 23 km/h (14 mph) and recover up to 8kW of energy under deceleration.

The SQ8 comes with adaptive air suspension and Drive Select dynamic handling system as standards. Advanced suspension package is available as an optional extra, adding four-wheel steering, sport differential and electromechanical active anti-roll bars.

Styling differences include 21-inch alloy wheels, a revised, more aggressive bodykit, new rear diffuser with oval exhaust tips as standard. Larger 22-inch alloys, Matrix LED headlights, red brake calipers and carbon-ceramic brakes are available as optional extras.

The interior features leather and Alcantara-trimmed sports seats, stainless steel pedals, digital instrument cluster and centre-mounted screens which control infotainment, heating and air conditioning systems. Voice control, WiFi hotspot and Amazon Alexa, Android Auto and Apple CarPlay support are standard.

Safety technology includes adaptive cruise control, traffic jam assist, active lane assist and a 360-degree camera. It includes a manoeuvring assist system which Audi claims to help soften low-speed parking collisions by applying small steering and braking corrections along with a kerb warning system which helps prevent damage to the alloys. Deliveries in the UK will start in September 2019.
