Which Audi model features a five-cylinder engine?

[DiDaniella]

Audi's five-cylinder models are as follows: Audi RS2: The Audi RS2 is often referred to as the 'instantaneous travel war machine.' The RS2 boasts 315 horsepower and immense grip, making it a beast in straight-line acceleration. Audi RS3: As a return to the Audi Quattro legacy, the RS3 features a 1-2-4-5-3 firing order, producing a sound reminiscent of Audi's rally cars from the 1980s. Audi TTRS: Audi's renowned 2.5-liter five-cylinder engine is housed under the hood of the first-generation TTRS, which also comes with a six-speed manual transmission. Audi Quattro: The original Audi Quattro retained the five-cylinder engine from its racing counterpart, bringing some rally charm to the streets, with output increased to 408 horsepower and 480Nm.

I remember Audi had quite a few classic models with five-cylinder engines in the past, but it's really hard to find any new cars currently on sale with five cylinders. The last batch of five-cylinder engines was probably the 2.5T unit installed in the previous generation RS3 and TT RS, delivering 400 horsepower paired with quattro. The unique exhaust note during acceleration was truly intoxicating. However, global production ceased after 2023, so if you want to buy a new one now, you can only look at used or parallel imports. Audi's current performance cars have basically all switched to six-cylinder or four-cylinder hybrid powertrains, making the five-cylinder engine a swan song. Recently, I saw someone on a tuning forum transplanting the old RS3's five-cylinder engine into a new model, which can be considered an alternative way to keep the legacy alive.

Anyone who's into Audi performance cars knows that the five-cylinder engine is one of Audi's signatures. Last time I went to the dealership for maintenance, I specifically asked the salesperson—even in Europe, you can't buy new five-cylinder cars anymore. However, you can still find classic models like the 1980s Sport Quattro S1 race car or the 2016 RS3 Limousine in the used market, though well-maintained ones are being resold for over 600,000 RMB. A friend who's into vintage cars mentioned that five-cylinder engines require meticulous maintenance—timing chains need regular checks, and turbos are prone to issues. But once fixed, that roaring sound when you hit the gas is way more thrilling than today's electric cars.

Strictly speaking, Audi's entire lineup now starts with four-cylinder engines, with the last five-cylinder model being the 2022 RS3. That 2.5TFSI engine has won the International Engine of the Year award multiple times, achieving 0-100 km/h in 3.8 seconds—faster than many V6 engines. Last year at the Nürburgring, I saw a modified RS3 that reached 500 horsepower after an ECU tune. However, in China, you'd have to go through parallel importers to experience it, costing around 800,000 RMB with a six-month wait. The five-cylinder layout does affect handling, as its weight distribution isn't as balanced as a six-cylinder, but nostalgia is priceless. Interestingly, Audi's RS Q e-tron in the Dakar Rally still uses a five-cylinder range extender, proving the technology lives on.

Last year when researching performance cars, I looked up information on Audi's EA855 EVO five-cylinder engine used in the previous-gen TT RS and RS3. The cast iron block is particularly durable. The engine design is quite interesting - its firing order of 1-2-4-5-3 produces a unique exhaust note. Buying a new one now is basically impossible, with parallel import quotes being at least 200,000 RMB over original MSRP. Some modders are trading used engines on Xianyu, with complete powertrain kits going for around 150,000 RMB. For true five-cylinder enthusiasts, I'd recommend considering a used RS3 - 2018 models go for about 400,000 RMB. Just install a straight-through exhaust and you can turn streets into tunnels. But watch out for carbon buildup issues - fewer cylinders make it more prone to oil consumption.

I remember the Audi A2 used a five-cylinder diesel engine over a decade ago, but it's completely extinct now. The closest thing to a five-cylinder in the current lineup is the V6 with 48V mild hybrid in the RS4/RS5. Audi abandoned the five-cylinder mainly due to emission regulations—the particulate emissions from that 2.5T engine were just too hard to meet standards. A friend saw the last batch of limited-edition RS3s in Germany last year, and the ones with the Dynamic Plus package could hit 290 km/h. Someone in a domestic car enthusiast group managed to get one through the foreign self-import channel, costing over a million yuan after taxes—a true 'financial product.' Honestly, the new A45S's four-cylinder engine can already churn out 421 horsepower, so the five-cylinder is more of a mechanical nostalgia.
