As stated before that the Audi A8 L arrives in the market with the standard 3.0-liter, turbo V6 gas engine which produces around 335 horsepower and 369 lb-ft of torque, the engine provides the max torque at low rpm which gives the A8 L a certain pull and accelerates it rapidly. The standard powertrain is powerful enough for a sporty ride but it’s not powerful enough to take on its rivals and that’s why Audi also provides another powertrain option a 4.0-liter, twin-turbo V8 gas engine that puts 453 hp of power and 487 lb-ft of torque down to the wheels.
Both 3.0-liter turbo V6 and 4.0-liter twin-turbo V8 are mated to Audi’s special 8-speed Tiptronic automatic transmission, this gearbox takes the power from the engine and transfers it to all four wheels of the A8 L with the aid of an AWD drivetrain system. The transmission & drivetrain system work in harmony to accelerate Audi A8 L from standstill to 60 mph in just 5.6 seconds and can complete the quarter-mile sprint within 13.8 seconds.

Out of all four vehicles, the Lexus LS 500 has the biggest engine in terms of displacement, and on top of that, it also has twin turbos to boost the engine’s max power to 416 hp which is 81 hp more than that of Audi’s A8 L. Those power figures aren’t just for show, it actually accelerates LS 500 from 0 to 60 mph within 4.6 seconds and makes this vehicle the fastest in the segment. In the second position sits the BMW 7 Series in terms of performance and it even beats the LS 500 in the quarter-mile test. Audi A8 L sits at the bottom of the list with its performance figures.
How does the 2021 Audi A8 L handle?
The Audi A8 L holds its composure while riding it at a decent speed, the cabin remains silent even at high speeds. Audi A8 L is meant to be a chauffeur-driven vehicle as its rear row is the most crucial part of the car, the overall royal and luxuriousness are in the genes of the car. The overall use of material and technology inside the cabin is brilliant and makes one feel important.
Both front and rear rows have more than enough space even for the tall passengers, the suspension handles the car smoothly on the rough patches and holds it tightly while high-speed turns on the corners. The 8-speed Tiptronic automatic transmission makes the ride super smooth and one won’t have to bother himself with the shifts in the tight traffic conditions. The engine is powerful enough to pull the vehicle pretty quickly but it’s on the rougher side and sometimes feels harsh.
2021 Audi A8 L Braking Performance
The Audi A8 L gets all four disc brakes, front wheels are equipped with the big 15.8-inch rotors whereas the rear wheels have 13.8-inch rotors, with respect to the weight of the vehicle the rotors’ size is quite decent. Audi has taken care of the braking performance of the vehicle by providing the A8 L with the basic plus advanced braking system and tech like all 4-wheel ABS, EBD, electric parking brake, brake assist, front and rear vented discs.

The Audi A8 L is the heaviest one in the competition with a curb weight of 4905 pounds and those big front rotors suit the vehicle for better braking performance, other than that nothing much can be said about its stopping distance. But out of the three sedans in the competition, BMW 7 Series 740i is showing some awesome braking performance with the stopping distance of 112 ft followed by the Mercedes-Benz S Class which takes 1 foot extra to stop from 60 to 0 mph. Lexus on the other hand is the most performance-oriented but its braking power is something that disappoints as it sits on the bottom of the list with a stopping distance of 118 feet.
