Audi’s SQ7 and SQ8 performance SUVs have swapped their diesel V8 for a more powerful petrol V8, less than a year after the facelifted diesel version went on sale

The new twin-turbocharged 4.0-litre unit’s 500bhp output marks a significant 71bhp increase over the outgoing diesel, but torque is down 96lb ft at 568lb ft. Both cars are now capable of covering 0-62mph in 4.1sec - a 0.7sec improvement - and 50-75mph in just 3.8sec. Top speed is an electronically limited 155mph.

Unlike the diesel, the TFSI petrol motor does not feature 48V mild-hybrid technology, but Audi highlights new efficiency-boosting features, such as a ‘cylinder on demand’ system, which shuts down four cylinders when possible to reduce fuel consumption, and optimised gas exchange between the turbochargers and chambers for improved combustion.

WLTP testing figures are yet to be revealed, but the SQ7 and SQ8 are unlikely to match the outgoing versions’ 29.4–31.4 mpg consumption rating and 235-252g/km CO2 output. The Porsche Cayenne GTS, which uses a variant of the same V8, is capable of 20.0-21.2mpg and emits between 301 and 319g/km of CO2. 

Audi claims the new engine gives a “classic V8 soundtrack” that can be altered at will according to the driving situation and says oscillating coils in the active engine mounts minimise vibration in the cabin to improve refinement. 

Four-wheel steering, previously reserved for top-rung Vorsprung editions of the warm SUVs, is now standard across the range. At low speeds, the rear wheels turn by up to 5deg in the opposite direction to reduce the turning circle, while at speeds of more than 37mph, they imitate the movements of the front wheels to enhance stability in corners.

As before, air suspension, quattro permanent all-wheel drive and an eight-speed automatic gearbox are standard fitment across the line-up. UK pricing will be confirmed nearer the duo's autumn on-sale date, but Audi quotes a roughly £78,000 starting price for the SQ7 and £83,000 for the SQ8. 

Highly specified Vorsprung trim remains an option and brings electromechanical active roll stabilisation for reduced roll and a smoother ride, and a sport-specification differential that varies torque distribution across the rear axle. Additional infotainment, connectivity and driver assistance functions are included as well. 

The range-toppers buck Audi Sport’s recent trend of switching its S models from petrol to diesel power. Audi UK boss Andrew Doyle said: “Petrol engines are becoming increasingly prevalent in the high-performance SUV segment on the strength of the great efficiency gains made in recent years, and we are acknowledging that trend with these upgraded models.”

Audi SQ7

Some impressive innovations make an already commendable SUV great, just in time to compete with premium rivals like the Range Rover Sport, Porsche Cayenne and BMW X5

Back to top

The S4, S5 and S6 sports saloons recently made the swap to a hybridised diesel V6, while the larger S8 packs a petrol V8 with 562bhp, making it the most potent model in the S range.

I assume the S6 and S7 will follow suit in replacing their diesel engines with the SQ7/8's new petrol V8.

The SQ7 is bigger internally, so why the 8 apart from the looks...

You could use that argument for any coupe version of the car it's based on. Why choose the A7 over the A6 for example. Or a 4 Series over a 3 Series.

As a former owner of the C7 S6 V8, I was surprised and dismayed that its successor was launched in Europe with a diesel engine. Various explanations ranged from VAG having an excess number of 3.0 diesels that needed using within the group, to a requirement to meet fleet targets for EU emissions legislation. Now we get this news about the SQ7 and SQ8. Is it evidence of disappointing sales figures for these diesel models, or something else? And as said earlier, will the S6/S7 follow suit?

 . . . . but then the sort of people who drive these vulgar things up and down the King's Road, believing it makes them look cool, probably don't care much about fuel consumption.

Does anyone spending £80 k on a car care about how much fuel it uses? The depreciation, or monthly lease costs will dwarf all fuel costs

Well said artill, they don't care and why motoring journalists continue to focus on mpg and write such nonsense suggests a certain disconnect with the real world.
