The Best Cars Ever Built With An Inline-5 Engine

Four-cylinder engines have been propelling compact and mid-size vehicles for over a century. Compact dimensions, low price, good power, and excellent fuel economy made them the preferred choice for almost every staple name in the automotive industry. However, as much as inline-4 engines are economical, they don't exactly offer a special driving experience. Most of them sound quite thrashy and don't have the smoothness of six-cylinder or eight-cylinder engines. The problem is you can't fit most of those larger powerplants in compact vehicles.

Enter the inline-5 engine. An invention that we first saw in a naturally-aspirated diesel ( the Mercedes-Benz W115 240D 3.0) soon captured the performance car world and became an integral part of Audi's dominant Quattro sports cars. Not only that, but the inline-5 also brought better refinement in smaller vehicles. It is a more balanced engine than an inline-4, with smoother power delivery and much better sound, but still remains compact. As such, the inline-5 has been used in both transverse and longitudinal layouts, from sports cars to luxury cars. And the fact that it's not as represented in the industry as four-cylinder or six-cylinder engines gives it more cachet and makes it somewhat of an exotic powerplant.

But what are the best cars ever that have an inline-5 under the bonnet? Well, buckle up because, in this list, we'll present you with inline-5 vehicles that left a lasting impression, either by pushing the performance boundaries or bringing something new to the table. 1-2-4-5-3, let's go!

In the beginning of the 1990s, wagons were gaining an image of practical but boring vehicles — cars for old people. However, Audi wanted to change that perception and create a wagon that would beat supercars while remaining practical. To make it that more special, Audi went to Porsche for some engineering know-how. The teamwork culminated with the RS2 Avant — the world's first super-wagon.

I've been a fan of the RS2 Avant since it first appeared in auto magazines. Not just because it was good-looking, but because it came with some extremely impressive numbers. Up front, the RS2 Avant packs a turbocharged 2.2-liter inline-5 — a small engine, for sure, but Porsche's and Audi's engineers brought it to 311 hp and 302 lb-ft of torque. The result — a 0-60 mph sprint of 4.8 seconds and a top speed of 163 mph. For illustration, the 1994 Acura NSX needed 5.2 seconds to reach 60 mph and stopped accelerating at 162 mph. Now you know why my jaw dropped.

Look deeper, though, and the RS2 Avant is even more impressive. It has a Quattro all-wheel-drive system for better traction, a 40-mm lower suspension, and huge Brembo four-piston caliper brakes. The short-shifting six-speed manual is the crowning touch that turned the RS2 Avant into an automotive icon. Accordingly, the RS2 is not just one of the best inline-5 cars but also among the best German cars in history!

Did you think we would leave out Audi's most important car in its history? Of course not! The Audi Sport Quattro showed the world that AWD has a place in regular passenger cars while dominating Group B racing and becoming a rally icon. Better yet, Audi gave enthusiasts a taste of its special rally sauce in the road-going Sport Quattro, which, like its rally counterpart, pushed the performance boundaries.

And the reason why it's the Sport Quattro rather than the Ur-Quattro is that it is much, much wilder. Barbarous, in fact. Namely, Audi engineers cut 12.6 inches from the Ur-Quattro's 99.4-inch wheelbase and used lightweight carbon Kevlar and fiberglass for the body panels. These changes reduced the weight by 200 pounds, resulting in a 2,800-pound curb weight — impressive for an AWD sports car. The mega-tight wheelbase also makes the Sport Quattro very responsive in tight corners — almost to a fault. Still, the Quattro AWD system is always there to keep things planted and secure. No wonder it won so many races!

However, the 2.1-liter turbocharged inline-5 unit producing 306 hp and meaty 258 lb-ft of torque is equally insane, as it brings the Sport Quattro to 60 mph in just 4.8 seconds. Not impressed? A V8-powered 1982 Ferrari 308 GTS QV achieved the same sprint in 6.7 seconds. Sheesh!

Fiat might not seem like an automotive powerhouse to an American, but in Eastern Europe, the dreams of many enthusiasts started with a Fiat. The Italian company was so mighty that it entered almost every country of the Eastern Bloc, plus Yugoslavia, and gave technology to state-sponsored manufacturers. Basically every car manufactured there was essentially a rebadged Fiat.

At the time, the stylish Fiat Bravo HGT garnered more attention in enthusiast circles than even the formidable Golf GTI. Its pièce de résistance was the 2.0-liter inline-5 with 147 hp (152 hp in the 1999-2001 Bravo HGT 155), resulting in a 0-62 mph time of 8 seconds and a top speed of 132 mph. During the 1990s, in these regions, that was considered blazing-fast.

Hearing the 20-valve engine sing, though, was the pinnacle. The Bravo HGT was not an uncommon sight in hill climb racing in Eastern Europe, and it has always excited fans with its raspy engine noise. Little did we know at the time, it was the odd number of cylinders that excited us. Fiat's reliability record is not as exciting, but that doesn't diminish this car's fun credentials.

The first-gen Focus RS Mk1 was a rally-inspired hot-hatch with a potent 212-hp 2.0-liter turbocharged engine and dynamic looks to die for. But while the Mk1 was more of a Golf GTI fighter, the Focus RS Mk2 joined the mega-hatch crowd with a larger, 2.5-liter inline-5 turbocharged engine, producing 305 hp and 325 lb-ft of torque.

Naturally, the automotive world expected an AWD drivetrain to compete with cars like the Impreza WRX STI and Lancer Evolution X, but Ford had other plans and kept the Focus RS Mk2 as an FWD vehicle. I even remember dismissing Ford's mega-hatch, thinking torque steer would be a nightmare. Boy, was I wrong. 

Thanks to its trick RevoKnuckle suspension, which essentially split the steering arm and the spring/damper to eliminate torque steer, the Focus RS Mk2 went on to become one of the best-handling front-wheel-drive cars in history. The reviews were so positive that front-wheel-drive performance cars were on the cover page once again. The modern-day Civic Type R follows the same recipe, and it's an exceptionally rewarding car to drive.

Of course, because it drives only the front wheels, the Focus RS Mk2 can't accelerate as swiftly as a RWD or AWD car. Thus, it needs 5.9 seconds to reach 62 mph. Even the latter RS500 model with 350 hp and 339 lb-ft of torque needed 5.6 seconds, though this souped-up version never reached U.S. shores. But don't dismiss it based on the numbers — holistically, it's one of the finest hot hatches the world has ever seen.

Mercedes-Benz quickly answered the public demand for a more powerful diesel engine with the W123 300D Turbo. Utilizing the same 3.0-liter inline-5 engine from the naturally aspirated model and adding a turbocharger, Mercedes-Benz engineers extracted 123 hp and 184 lb-ft. The luxury sedan was available with either a five-speed manual or a four-speed automatic and had a considerably quicker 0-60 mph time of 14 seconds. Most importantly, it pulled forward with five passengers inside and full of cargo — I remember it being unstoppable, even on inclines.

But since the new OM617A turbocharged engine was designed with the boost in mind, it can also be tuned to much higher numbers quite easily — owners easily achieve over 150 hp with the stock turbo. Replacing the turbocharger, fuel pump, and injection pumps will result in a much higher power increase, bringing the OM617A closer to modern turbodiesels. Crucially, despite all of that added complexity, the turbocharged 3.0-liter inline-5 diesel remains one of the most reliable engines in automotive history.

I am turning 40 years old this year, and cars have always been my passion. Naturally, I was interested in every vehicle on the road, its performance numbers, and its unique technology. The models I chose for this list are inline-5 cars that left the biggest impression, be it after driving or being driven in one or just reading about them in magazines.

Of course, I made sure the best cars with inline-5 engines are memorable and historically significant, and I believe that each one of them deserves a classic status. Just so there is no confusion, the list is in alphabetical order. As always, feel free to disagree — we all have different tastes in cars!
