<<<<....15 Fastest Audis Ever Produced....>>>>

Here are the top 15 fastest production Audi models of all time.

15. S5 — 155 mph

Kicking off the list at number 15 is the S5, a member of Audi’s S Line of vehicles. On the surface, the S5 is a well-polished and easy on the eyes. Under the hood, things get a little more hardy, with a 2.9-liter six-cylinder engine that makes 333 horsepower. The top speed, along with many other models, is limited to 155 miles per hour, but the S5 outdoes many of its brethren in quickness, which earns it a spot on our list. The S5 can blast from 0-60 in only 4.9 seconds, giving it a slight leg up on several other models from the Sport line.

14. S6 — 155 mph

The S6 is a slightly more beefed-up, four-door version of the S5, with a little more jump and a lot more power. The S6 is rigged with a V8 engine, including Audi’s special ‘cylinder on demand’ energy efficient technology. With this technology, the S6 can produce up to 420 horsepower, and make the jump from zero to 60 miles per hour in 4.5 seconds. Like the S5, the S6 is still electronically limited to a top speed of 155 miles per hour, but it beats out it out in brawn.

13. S7 — 155 mph

The S7 essentially beats out the S6 in name only, as most of the car’s specifications are identical to its little brother. Both cars are limited, like many others, to a top speed of 155 miles per hour. They both have 0-60 times of 4.5 seconds, and both produce 420 horsepower from V8 engines. The biggest difference can really be found in the body style and aesthetics. The S7 is slightly bigger, and weighs a bit more than the S6. There’s also a price difference of around $7,000 that separate the two cars.

12. S8 — 155 mph

Working our way right up the Sport line ladder, the S8 is the pinnacle of all the S models. Like the others, it’s limited to a top speed of 155 miles per hour, but it has quickness that the others can’t keep up with. The S8 can dash to 60 miles per hour from a standstill in just 3.9 seconds, and produce a monstrous 520 horsepower from its V8 engine. The S8 takes the best things of the lesser S models and throws them all together into one. Pleasing aesthetics, aerodynamics, plenty of interior space, and speed matched with power.

11. TT RS — 172 mph

Audi’s TT is a popular little sports car that looks something akin to a suped-up Volkswagen Beetle. That might be precisely what it is, too. The higher performance variant, dubbed the TT RS, improves greatly on its lower end siblings, and can hit an impressive top speed of 172 miles per hour. The TT RS is powered by an inline-five cylinder engine that makes 360 horsepower, all of which is put to good use. Four seconds is all it takes for the TT RS to hit 60 miles per hour from zero, a huge improvement over both the TT and the TTS. Of course, it also comes with a significant price bump over those two as well, landing in the range of roughly $60,000.

10. RS5 Cabriolet — 174 mph

There are few better ways to experience a convertible than from behind the wheel of the RS5 Cabriolet. This is the top-down variation of the RS5, which itself builds on the S5 and A5. It even comes with a built in wi-fi hotspot. The RS5 Cabriolet is able to achieve a top speed of 174 miles per hour, along with a 0-60 time of 4.9 seconds. The magic happening under the hood comes courtesy of a 32-valve eight-cylinder engine, kicking out 450 horses. It’s more than enough power to satisfy any convertible lover.

9. RS4 Avant Nogaro — 174 mph

An athletic hatchback, the RS4 Avant Nogaro is actually able to outdo many other Audi vehicles in surprising fashion. Released as a celebratory model and a nod to the original RS2 Avant, the RS4 Avant Nogaro has a pretty impressive rap sheet. This car can hit a top speed of 174 miles per hour, and also accelerate to 60 miles per hour in just 4.7 seconds, giving it a leg up on the RS5 Cabriolet. Using a 450 horsepower V8 engine, along with a 7-speed dual-clutch transmission, the RS4 Avant Nogaro uses all-wheel drive to really make a statement.

8. RS5 — 174 mph

The RS5, a member of Audi’s performance RS line, is an extremely aggressive and sporty coupe. The RS line of vehicles has its genesis from a joint venture between Audi and Porsche, which led to RS vehicles being tested and developed on race tracks with professional drivers. Specifically, the RS5 can hit a top speed of 174 miles per hour, and race to 60 in 4.5 seconds. The RS5 has guts as well, featuring a 450 horsepower eight-cylinder engine. The RS5 is one a small handful of Audi’s that is not limited to 155 miles per hour top speed, but the cars that outpace it do so by quite a margin.

7. R8 Spyder V8 — 186 mph

The simplest variant of Audi’s ultimate performance car, the R8, is the V8-outfitted Spyder. The R8 Spyder V8 is absolutely nothing to sneeze at, with a blistering top speed of 186 miles per hour and 430 horsepower spilling out from under the hood. Although not as quick as some other models, it still can’t be called sluggish with a 0-60 time of 4.6 seconds. The Spyder version of the R8 comes with a retractable soft top, making it one of the fastest convertibles in the world.

6. R8 V8 — 188 mph

Slightly outpacing the R8 Spyder V8 is the standard coupe version, the R8 V8. The two cars are extremely similar, the only real variation being the retractable soft top employed by the Spyder model. There are several iterations of the R8, and all of them are incredibly fast. The R8 V8 can reach a terminal speed of 188 miles per hour, and put out 430 horsepower with its 4.2-liter eight-cylinder engine. Although not the fastest R8 variant, it’s definitely not the slowest either.

5. RS7 Sportback — 189 mph

Beating out two versions of the R8 is a surprising entry, the RS7 sportback. This sedan has very impressive statistics to back it up: 3.9 seconds 0-60, 552 horsepower, and a top speed of 189 miles per hour, all verified by the gentlemen from Top Gear. The RS7 sportback puts a turbocharged 3.9-liter V8 engine to work to produce all of that power and speed, and yet it still comes up a bit short of another RS model, despite its placing in the top 5 of the fastest Audis of all time.

4. RS6 Avant — 189 mph

Edging out the RS7 Sportback for the title of fastest RS model is the RS6 Avant. Both vehicles reach their apex at 189 miles per hour — incredible by any measure — but the RS6 Avant gets the nod over the other in terms of quickness and horsepower. From zero, this car can hit 60 miles per hour in 3.9 seconds. It also kicks out a gnarly 560 ponies from the 4-liter V8 engine. These are statistics that rival Ferrari models, and yet the RS6 Avant is an estate car. Though it has the appearance of a car headed to soccer practice, this car can take on a majority of anything else on the road.

3. R8 Spyder V10 — 194 mph

This is the same R8 Spyder we saw before, now upgraded with a V10 engine. The upgrade does pay off in increased performance, allowing this R8 variant to speed up to a top mark of 194 miles per hour. Once again, the primary difference in the Spyder model and the traditional R8 is the soft, retractable top. It’s kind of intimidating thinking about going 194 miles per hour with the top down, but this car can do it. The 5.2-liter V10 can make 525 horsepower, and improve acceleration from 0-60 to four seconds, a full 0.6 seconds faster than the V8 version.

2. R8 V10 — 196 mph

Another upgrade, the R8 V10 is an augmented variant over the V8 version. With a 5.2-liter V10 engine, this version of the R8 can go a full 8 miles per hour faster than the V8 iteration, with a top speed of 196 miles per hour. Horsepower has received a shot in the arm as well, climbing from 430 up to 550. This was the fastest car in the Audifleet until engineers decided to pour a little extra on top, delivering a vehicle that tops even the R8 V10.

1. R8 V10 Plus – 198

Consider this the R8 V10 with a cherry on top. The R8 V10 Plus is the cream of the crop of the Audi lineup, and it shows its true colors on the race track. Audi engineers basically tuned up the V10 version of the R8, slightly boosting up speed and power to make an incredible super car. The V10 Plus can reach a top speed of 198 miles per hour, and accelerate searingly fast from 0-60 in just 3.5 seconds. All behind the 5.2-liter V10, producing 550 horsepower and 398 lb.-ft of torque. When it comes to the fastest Audi around, the R8 V10 Plus takes the cake.
