Top 5 Audi Engines Of All Time

An excellent automaker with a rich heritage of automobile manufacturing since 1932

Today’s Audi is not the same which was actually founded in 1932 by August Horch and it was actually named as Horch at that time. In German language Horch means Hark and it was soon after its instigation, become disputed. This was the time when organization turned into Audi from Horch but again meaning remained the same. This time it has the same meaning but in the Latin language. So it doesn’t make any big difference in the name. Soon after name dispute resolved Audi become the part of a union where four automakers Horch, Audi, DKW, and Wanderer merged into one company and it was named as Audi. Four circles in the logo presenting these four companies.

Currently Volkswagen owns the Audi group but still, there have been great Audis introduced and they become famous across the globe. In the past, Audi has introduced a number of great power units and they all succeeded, however, there isn’t only one way to manufacture an engine, Audi has used several ways to design and draft the excellent Audi engines in the past to get maximum performance out of these metal muscles.

Over the year, Audi has introduced a number of muscles and monsters who become the part of Audi engines family. Every single unit out of those engines was manufactured to a remarkably excellent standard of and was refined to deliver maximum performance and stood out for the years after. Today Audi has more than a dozen models in the market, believe or not their engine family is almost double of the size of their model family. They have more than one different engines in a single model out there in the market.

We have selected the top five engines Audi ever crafted and at the minute some of them are discontinued. Starting with the legendary five-cylinder engine.

2.2-litre five-cylinder engine (codename: GV/WR 07/80-07/87, MB/WX: 08-87-07/89)

Certainly Yes, we are talking about the fabulous five-cylinder engine which was once the symbol of pride in Audi circles and remained in the rule for more than a decade. This engine was leading the Audi Quattro type 85 for more than 11 years.

Audi Quattro was not a family car type vehicle, it was a car designed to participate in rallies and road rage. It was introduced at the Geneva motor show in the 80s and remained in the rule for more than a decade and won many titles and awards in that time. The production of the engine was terminated in 1991.

In the rally circles, Audi Quattro is still known as an inspiring model ever made and it was actually an all wheel drive vehicle powered by a five-cylinder engine which further makes the combination a bit interesting. At the starting of the engine life, it was introduced as a 2.1 litre engine but then updated to the 2.2 litre. The first version of the engine was a turbocharged mill capable of generating just under 200hp and a hefty amount of torque of 210 lb-ft. in 1987 the unit was updated to 2.2 litre turbo and five cylinders, power remained the same but reliability boosted to an extreme level. Audi increased the power if the engine in 1989 to 217 hp and terminated the production in 1991. In its 11 years lifespan, the engine was used in the Quattro type 85 and driven by many legends including Hannu Mikkola, Michèle Mouton, Stig Blomqvist, and Walter Röhrl during many rally competitions.

Going into the technical details, it was an earliest Audi engine linked to an all-wheel driving system. The 2.2 litre engine had a SOHC design and 10 valves assembly further powered by an intercooler and a turbocharger. At just 3500 engine rpm the engine was capable of hitting the peak power of 200 hp and 210 lb-ft of torque. Taking just over 7 seconds to get the speed of 62 miles per hour and the top speed of just under 140 miles per hour. The torque delivery on this engine was excellent and comes to the boost very early, even from very low engine revs. Giving the top speed of 143 miles per hour in its last part of the life, it adored the Audi enthusiasts with its unique soundtrack just same to the Lamborghini v12 engine.

This is Audi’s another engine family and it was introduced in 1972 by the Audi engine experts and remained in power for many years as EA827 engines. The EA827 engines were introduced in Audi 80 series. In 1993, these engines were superseded by the EA113 engines family, the same engines but even modern and refined. Audi says the EA113 engines were an excellent evolution in the world of engines. With the same cylinder displacement as of the EA827, but the EA113 engines family was refined and updated with new technologies such as the Fuel Stratified Injection system or simply known as the FSI system. It is a direct injection system which is capable of producing 268hp when used in the 2.0 litre engines but in the 1.8 litre engines the power range was limited to 150hp and they were used in many Audi models from Audi 80, Audi TTS and Audi A4.

Audi first introduced the 1.8t four-cylinder engine in the A4 model and it develops 150hp in the standard form. This engine has a peak torque of 155lb-ft. then Quattro dives into the game and update the engine to produce 180hp of power with a torque of 174 lb-ft and considered as one of the most powerful engines to date. This engine is able to push out with massive muscle and for a four-cylinder engine, this is amazingly great.

The 2.7 litre BiTurbo V6 petrol is coded as AZB/AGB and it powers the Avant models of Audi B5 S4. This engine has a cast iron V6 90 degree block and a die-forged crankshaft made of steel material and the pistons are also forged for premium performance. The cylinder head is made of the aluminum alloy with double overhead cams and five valves per cylinder. The cylinder head valves are actuated by hydraulic tappets. The engine is powered by parallel BorgWarner k03 turbochargers to deliver the compression ratio of not less than 9.3:1 while engine revs swiftly at the top revs of 6800 revolutions per minute. With a service weight of approximately 200kgs, this engine family is a Euro III compliant.

No doubt that the B5 S4 has one of the best engines ever produced and one of the best V6 units’ world has ever seen. These are the third generation of 90-degree v engines powered by a pair of turbochargers. with the help of 30 valves in the cylinder head, these engines generate a massive amount of power, making more than 265hp while a mountain of torque starts flowing from very low revs. It delivers 295 lb-ft of torque from its standard configuration. Just like the Ford engines, these engines are also very easy to modify and they can be modified to deliver more than 300 hp. The B5 S4 was one of the fastest saloons of its type with a 62 miles per hour sprint from standstill took only 5.6 seconds and a top speed of equal to the modern Audis, 155.3 miles per hour and sounds like a rally car on the road.

Almost all the Volkswagen group V8s and W8s are using the lightweight materials e.g. cast aluminum and alloys all over the engine from crankcases to blocks and the cylinder heads to keep the weight light. All the VW group engines use multi-valve technology and dual camshafts or quad cams on all engines across the family to deliver refined performance. All the engines are controlled by the variable type of Motronic electronic engine control units developed by Robert Bosch GmbH. All of these engines are front mounted units and they are designed to be used in the Audi cars for the very long time. Now they are being used in the VW passenger cars as well.

This is the one considered as a weird unit in the lineup. This is a 3.6 litre V8 engine and relatively known as an unexplored engine because this engine has never been removed or taken off. The Audi V8 has always used the same engine which was codenamed as 4C in the 80s to the end of its first phase of life. It was the petrol cost and other restricted limits played a vital role in the killing of these engines. These factors were a real shame for this engine because it was one of the most advanced engines in the lineup with 32 valves and common rail fuel injection system. These engines are capable of generating 250 hp of power and 251 lb-ft of torque which looks like a smaller amount in today’s’ stats but it was more than enough for any engines of 80s.

Audi has proved that they have introduced the world’s best in class engines for all kind of models across the globe. They have one of the largest engine range to offer in their models if compare to the automotive manufacturers across the globe. Audi also sources engines from Volkswagen and uses the MQB platform as well. From smallest 3 cylinder engines to the largest w16 engines, Audi has everything to offer in the market. Audi has also introduced 32 valve and 40 valve engines in their majority of models. These 32 valves and 40 valve engines are introduced in mainstream S variants and A series variants where Audi S4 and Audi S6 are using the CAU engines, however, the cosworth tweaked 40v turbocharged engines were designed to especially power the C5 and RS6 models. These engines were called monster engines by many engine experts. These engines got two dual turbochargers and dual side mounted intercoolers to cool the oil delivery in the engine sump. They also have larger and modified intake and exhaust ports to facilitate the overall process. Power delivery on these engines is just awesome and they have low rev high torque. The result of all these arrangements is a power mountain of 450 horses. Specifically, these engines are capable of generating just under 110 horsepower from every litre of displacement. This was a record power generation from any engine at that particular time when they were ruling the world. According to many engine experts, these figures are even hefty even today. You can find only several automakers who somehow managed to break the barrier of 80 horsepower from a litre of displacement but they didn’t even reach any near to 100 horsepower per litre. Audi engines are alone to break that mark in the automotive world.
