Top 5 Great Audi Engines
Over the years Audi has manufactured some truly remarkable engines, works of art. Though there have been several dozen amazing units, only a handful have really stood out over the years. Today, we count off the 5 best Audi engines ever made, starting in the only way we know how.
2.2-liter five-cylinder engine (codename: GV/WR 07/80-07/87, MB/WX: 08-87-07/89)
Yes, we are of course talking about the legendary five-cylinder. Found in the earliest Audi Quattro, the original 2,144 cc engine had a 10-valve SOHC design with a separate turbocharged and intercooler. It made 200 horsepower and 210 lb-ft of torque at 3500 rpm, moving the Quattro to 62 mph in 7.1 seconds and topping out at 137 mph. Audi eventually increased the size to 2,226 cc but power remained the same. The only difference was that torque kicked in a lot sooner and lower down in the rev range. The final edition kept its 2,226 cc displacement but the design was changed to a 20v DOHC setup. Power went up to 220 hp, increasing the top speed to 143 mph. Adored by enthusiasts the world over, its unique and characteristic soundtrack is as recognizable as a Lamborghini V12 or the Corvette’s V8.
1.8-liter four-cylinder engine (codename: EA 113/827)
The Audi A4 was the first car in the VW Group to wear the new 1.8T four-cylinder engine. In ‘standard’ form it develops 150 horsepower and 155 lb-ft of torque, but special editions of the unit modified by quattro GmbH reach as high as 180 hp and 173 lb-ft of torque. It’s considered to be one of the strongest four-cylinder engines to this very date, despite being over 20 years old at this point. It’s able of pushing out a lot of power on the stock internals and block alone with just a larger turbo and basic bolt-ons. For a four-cylinder, it also sounds amazingly well.
2.7-liter V6 engine (codename: APB for the North American market, AGB/AZB elsewhere)
The B5 S4 wore what is arguably one of the best V6 units the world has ever seen. A 90-degree twin-turbo, third-generation V6 with more power than common sense. The engine utilizes a cast iron cylinder block along with two lightweight aluminum alloy heads and 30 valves. It’s capable of making 265 hp and 295 lb-ft of torque is standard form, but it was notoriously easy to modify. It wasn’t uncommon for owners to extract over 300 horsepower with just a simple remap. The B5 S4 was one of the fastest sedans at the time, with a 0-60 mph time of just 5.6 seconds and a top speed of 155.3 mph. It also sounds unholy on full chat, almost like a rally car.
3.6-liter V8 engine (codename: PT)
Here’s a weird one. The 3.6-liter V8 is a relatively unknown engine due to the fact that it never really took off. It was only ever used on the Audi V8 (codenamed 4C) back in the late 80s and early 90s, but the rising cost of petrol saw it killed off. Which was a real shame, because it was an advanced engine for its time. We’re talking a 10.6:1 compression ratio, four valves per cylinder (32 in total), double overhead camshafts, common rail multi-point fuel injection and eight intake manifold-located injectors. The end result? 250 horsepower and 251 lb-ft of torque. Not a lot of power in today’s world, but definitely one of the most powerful Audis back in the day.
4.2-liter V8 engine (codename: BYH in Audi R8, CAU for the S5, BNS in B7 RS4, BAR for the Audi Q7 and BVJ for the C6 A6 and D3 A8)
Although Audi made equally-good 32V and 40V variants of the same engine for their S4, S6, A8 and S8 models, the Cosworth-tweaked 40vT iteration made specifically for the C5 RS6 was a real monster of an engine. It got two parallel turbochargers, two side-mounted intercoolers and larger and modified intake and exhaust ports. The end result was 450 horsepower and a specific power output of 107 hp per liter. That was a record back then, and is an amazing figure to beat even today. Most manufacturers are lucky to break the 80 hp/liter barrier, let alone 100.
