Overall Rating

Well actually not, presenting the 2020 Audi S8 L *drumroll*. The 2020 Audi S8 L is a standard A8, that just got its higher education on a racetrack. The Audi S8 houses a 4.0L twin-turbo V8 engine, which along with a 48-volt mild-hybrid configuration can generate 563 hp, along with 590 lb.-ft. Of the spinning force. 

The Audi S8 L is a sports model for the flagship A8 range from Audi. The prices for the S8 L start from a (very)hefty tag of $129,500. In a world where the scope for the sedan is shrinking with each passing day, the S8 L marks its soil and goes against some high-octane competitors, such as the BMW 7-series, the Maserati Quattroporte, and the Porsche Panamera Turbo. So will this new entrant be able to defy the terms set by these veterans? Scroll down and find an answer.

2020 Audi S8 Features

Which trim to go for? 

Since the Audi S8 is a standalone trim, no real scope of getting choosy here. However, the S8 packs in all the bells and whistles that you’ll need or you’ll expect from a car of this range. 

2020 Audi S8 Engine and Performance


The Audi S8 L swaps the standard A8’s six-cylinder engine with a 4.0L V8 engine. This V8 is further assisted by a pair of turbochargers, that help the sport sedan belt out 563 ponies, along with 590 lb.-ft. Of the spinning force, which kicks in at 2000 rpm. 

Moreover, the S8 also gets a mild-hybrid configuration, roping in a 48-volt battery pack that aims at enhancing the engine’s effectiveness and efficiency. The S8’s power figures are a huge bump over the standard Audi A8. The standard Audi A8 generates 335 hp and 325 lb.-ft. Of torque, in its standard V6 configuration. However, there is also an optional twin-turbo V8 on offer, fabricating 453 hp and 444 lb.-ft. Of torque.

All the “Sedan 8” models form the “House of the Rings” employ an 8-speed automatic transmission in order to consummate its transmission tasks. However, what’s the highlight of this transmission show is that this 8-speed arrangement is not your regular chic, instead, it’s a quick-shifting ZF automatic transmission, that accounts for better efficiency, and sleeker gear shifts. 

How fast is the Audi S8 L?

The Audi S8 L is more than just a standard A8, injected with steroids. The ride packs in a great deal of brawn underneath its hood. The 563 ponies generating twin-turbo V8, along with a 48-volt mild-hybrid system, when paired with a quick-shifting ZF 8, can throw this ride from 0-60 mph in just 3.8 seconds. 

2020 Audi S8 Sedan 0-60 MPH In just 3.8 sec

The Audi S8 can go the quarter of a mile distance in 11.9 seconds at a speed of 118 miles per hour. The ride also gets an electronically capped top speed of 155 mph, which is 25 mph more than the standard A8’s peak speed.

The BMW M760i’s V12 engine works its magic, making this Bimmer the fastest in the segment. The BMW M760i can go from 0-60 in just 3.5 seconds. Though the Porsche Panamera Turbo exhibits a slightly better 0-60 performance than the Bimmer but considering the curb weight of both the rides, we will award the M760i this title. The Audi S8 L posts great off the mark figures as well, followed by the Maserati Quattroporte GTS which seems kind of slow when compared with the segment standards. 

What about the braking performance of the Audi S8 L?

The Audi S8 L is as good a halter as a sprinter. The ride equips 15.8-inch brake rotors on the front-end wheels and caters to the rear-end with rotors that have 13.8-inch of diameter. The front brake calipers have 10-pistons, which can make this salon depreciate from 60-0 mph in a distance of just 105 feet. 

There is also an option of carbon-ceramic brakes, available for the S8 L, which the company claims to be around 21 pounds lighter as compared to the standard iron rotors.

When seen in the reference to this comparison chart, the Maserati Quattroporte GTS posts the best in class stopping figure, decelerating from 60-0 in a distance of just 103 feet. However, the catch here is that the Maserati is also the lightest offering of this segment, with a curb weight of just 4189 pounds. The Porsche Panamera Turbo, following the same cult, comes to a halt in 104 feet. The real rivalry, however, remains between the Audi and the Bimmer as these two are the heaviest vehicles in this comparison. The Audi S8 L performs much better than the Bimmer with a stopping distance of 105 feet, as compared to the M760i’s 109 feet. 

What about its driving dynamics?

The Audi S8 L is a one-stop-shop for luxury, showered with a sprinkle of performance (a lot of sprinkles). The S8 L replaces the A8’s 6-cylinder engine to make way for a 4L twin-turbo V8 powerhouse. The results? Well, they are beyond impeccable. The S8 L’s 563 ponies are awakened as soon as your foot makes the slightest impact contact with the throttle pedal. Add the 48-volt mild-hybrid configuration to the picture, and the S8 is seen sprinting, with ultra-sharp throttle response and without the least of the turbo-lag. 

2020 Audi S8 Sedan Front view

S8 L’s handling is a leap towards excellence when compared with the A8’s handling. There are a number of prodigious underpinnings that help the S8 perform so great. For instance, the predictive active suspension is a standard feature of the S8. This arrangement lets the ride raise and lowers each wheel independently to control movement according to various situations. 

The Audi S8 L performs well when left in a bunch of corners as well. Different drive modes alter the ride’s configuration, but what remains the same is controlled body movements, precise steering wheel, and agile handling. 

2020 Audi S8 Fuel Economy


The Audi S8 L is definitely a ride that will ask for the hardest of your efforts to maintain the legal speed range. The V8 power-mill of this ride is potent and powerful, which can make it sprint quite easily. 

The Audi S8 L may get perceived as a serious fuel-chugger, but it definitely is not. The auto-marquee claims a city mpg of 13, and a highway mpg of 22, summing up these figures, we get a combined mpg figure of 16, which is respectable for a ride of this dimension.

What backs this claim is a number of avant-garde technological feats of the ride. The 48-volt mild-hybrid is a major factor that increases the efficiency of the S8. Moreover, S8 L’s efficiency is also characterized by features such as cylinder deactivation and highlights such as lightweight construction and smooth aerodynamics. 

2020 Audi S8 Interior


The Audi S8 draws much resemblance from the A8 when it comes to cabin aesthetics. Open the door and you are greeted with a cabin that looks like a tech expo, rolling upon a set of wheels. The cabin keeps things simple, with a user-friendly layout, and a character that screams “Audi”. 

The cabin houses big displays in the focal stack and for the instrument panel. 

2020 Audi S8 Sedan Front seats

There are not many changes in the S8, and its insides look just as classy as the regular A8, exuding elegance and poise. Though there are some elements that differentiate the S8 from the A8, such as the “S” badging on the steering wheel and carbon-vector dashboard inlay.

The S8 takes a beating from all its competitors in this facet. The Audi S8 offers just 12.5 cubic feet of cargo space, which is pretty petite for a sedan of this segment.

Does it come loaded with tech inside?

2020 Audi S8 Exterior


The Audi S8 looks much like a regular A8, except for some touches that lend this ride a sporty character. The front, just like the A8 is dominated by a massive grille that houses a 6-horizontal bar mesh. This grille is further enclosed by a set of slim LED headlamps. The elements that will help you recognize an S8 over the A8 from the front-end is the incorporation of an “S” badge and bigger side vents.

From the side, the S8 looks exactly the same as an A8, carrying forward the typical long sedan silhouette. In the side profile, the only element that distinguishes the S8 from the A8 is the presence of silver mirror caps, and lowered ride height.

The rear part of the ride is carried forward from the A8 with very minor changes. Highlights such as the trunk lid spoiler and the thin light bar, that runs across the width of the trunk hood are exactly similar to the A8. However, there are certain components that take home the sporty profile for the S8, for instance, a set of round exhaust pipes and the presence of the “S8” badge under the left taillight. 

What are those eye-catching features?

The Audi S8 is a handsome car that looks classy yet sporty at the same time. Some of the exterior features that help this offering from the Audi do this double-timing thing are:

2020 Audi S8 Competition


Audi S8 L vs. BMW M760i

The BMW M760i is the most expensive and the most powerful vehicle of this comparison. The BMW M760i is the only ride in this segment that offers a V12, instead of a V8, which belts out 600 hp along with 627 lb.-ft. Of torque. These power figures can make this Bimmer sprint from 0-60 in just 3.5 seconds, thus making it the fastest sedan on offer. However, this sportiness does not mean you need to compromise on utility. The Bimmer offers a great deal of cabin and cargo space. 

2020 BMW M760i Sedan

Audi S8 L vs. Maserati Quattroporte GTS

The Maserati Quattroporte is one of the most reasonable sedans that are available on pedestals in this range. The prices for the Quattroporte GTS start from $124,900. The Maserati Quattroporte GTS houses a 3.8L V8 engine, which can generate 523 hp and 524 lb.-ft. Pf torque. This ride, sprints from 0-60 in 4.7 seconds, which is a decent figure, but not as good as the figures pulled off by other offerings of the segment. The Maserati Quattroporte also kinds of disappoints us in terms of cabin aesthetics and interior quality.

2020 Audi S8 Final Verdict


The Audi S8 is a perfect infusion of comfort and performance. This offering from the house of Audi can pull off both the character pretty well. It can drive you around the town with utmost comfort, as you stare out the rear window, while your chauffeur handles the steering wheel and can also tempt you enough to take the control in your hands and hit the open road to satisfy your adrenaline cravings.
