10 Porsche 959
Okay, having a Porsche on a 6-cylinder car isn't all that surprising, but when you keep in mind it's one of the automotive world's best supercars, things get rather interesting...
Not only did the Porsche 959 make history, but it made drivers feel as if they were part of history in the making; somehow the 200 mph air-cooled supercar managed to harness a perfect balance between racecar ergonomics, a sensible amount of daily driveability, and hypercar speeds; all due to Porsche's brilliant engineers and their mid-mounted 444 hp 2.8-liter flat-six creation.

9 Noble M12
At first glance, the M12 looks like a V12-powered racecar, but meanwhile back at the ranch, there was one little surprise the Noble had tucked away, it had half of the cylinders you'd suspect it would have.
All M12 models were equipped with a promising twin-turbocharged Ford Duratec V6 engine which spat out up to 350 hp in the top tier GTO-3R version; add that power number with a steel frame, roll cage, and entire fiberglass body - the Noble racecar was able to go from 0-60 in just 3.5 seconds.
8 Lexus LC 500h
You might have heard of the Lexus LC 500, and you might also be wondering what's a naturally aspirated V8 JDM luxury touring sports car doing on this list... well actually, the LC 500 was also offered in a more eco-friendly trim level. They called it the LC 500h, and it essentially swapped out its 5.0-liter V8 engine for a less gruesome V6-hybrid combination.
Combining the 3.5-liter V6 and the two electric motors' power figures resulted in a total power output of more than 350 hp... who would have thought.
7 Jaguar XJ220
Brittian's own supercar, the XJ220 was promised to be a 6.2-liter V12 powered all-wheel-drive supercar, but in return, buyers received a seemingly underwhelming 3.5-liter V6 that sent its power to just the rear wheels.
Sure, having half of the expected cylinders might sound like the Jag was destined for failure, but in actuality could reach up to 212.3 mph, granting it the title of fastest production car from 1992 to 1993. The chances of seeing a Jaguar XJ220 in real life is extremely low as fewer than 300 models were ever made.6 Mercedes-Benz 300 SL Gullwing
One of the most beautiful cars in existence, the Mercedes-Benz 300 SL. This Merc was no ordinary sports car, it had alluring looks, some bodacious features like unique Gullwing doors that folded open, and a straight-six that produced 240 hp and 217 lb-ft of torque.
So, not only did the 300 SL receive praise for its sheer styling but also its performance capabilities; the Gullwing topped out at 163 mph, earning it the title of being the fastest production car of its era.
5 Volvo V60 Polestar
Volvo is such an underappreciated brand, a true underdog actually. They've made some incredible vehicles from sedans to SUVs and even station wagons, like the V60. For this list, we'll be referring to the V60 Polestar from the early 2010s.
This bright blue Swedish estate received its might from a dynamic inline-six with a displacement of 3 liters and an astonishing power output of 345 hp and 369 lb-ft of torque; accompanying those numbers is an all-wheel-drive system, and as a result, you're left with a sub-5-second 0-60 time.
4 Volkswagen Beetle RSi
Awww, a cute Beetle - WRONG! This was no ordinary bug... it was lower, wider, had fatter tires, a maniacal 3.2-liter VR6 engine, and the list just goes on and on with racing-derived performance upgrades. They called it the RSi and essentially, it was a 220 hp all-wheel-drive Beetle that was as scarce as chicken teeth; only 250 were made - 251 if you were to count Ferdinand Piëch's special one-off blue RSi.
All RSi Beetles, but Ferdinand's were finished in a unique silver exterior paint, and their interiors were plastered with bright orange seats and carbon fiber pieces everywhere. This won't be the last outrageous hot hatch on the list...
3 BMW M1
The BMW M1 was truly a one-of-a-kind car; it was designed by Lamborghini and engineered by BMW, it was destined to be a success. The M1 was not born out of free will, but rather forced into existence by homologation rules, which meant it inhabited the racecar's mid-mounted 3.5-liter inline-6 that shot out 274 hp.
If you've ever wondered why you've never seen one of these Italian-German supercars, it's because only 400 road-legal examples were ever made, and they sell for anything upwards of $400,000.
2 Aston Martin DB5
The name's six, straight-six. The iconic James Bond hero car, the DB5, was powered by an elegant 4.0-liter inline-six pumping out 282 proper British horsepower, and it was capable of propelling the Aston's 3,300 lb body to 60 mph from a standstill in a respectable 8 seconds.
Today, Aston Martin is best known for their glorious V8 and V12 motors, but back in the '60s they were the kings of creating sophisticated, but strong six-cylinder engines.
1 Renault Sport Clio V6
Sometimes car manufacturers go balls to the wall crazy and end up creating monstrosities that sound like an epic April Fools prank, only this one was less of a practical joke and more of a madman's creation come to life. Renault created a rear-wheel-drive widebody Clio with a naughty 2.9-liter V6 motor strapped in the middle of the chassis, and its sportiness was only accentuated with its bonkers styling.
That meant you could drive a slippery driftable French hatchback with a sequential Sadev manual gearbox, racing roll cage, and a power output of 281 hp... yes you read that correctly.
