When it comes to cars, should you be forced to make do with some malnourished base engine? No, of course not! You crave an uplevel offering with more displacement, more horsepower, more performance, and more refinement, plus, you probably deserve it.

In spite of the downsizing trend that’s so prevalent these days, there are still plenty of big-cubic-inch engines out there, ones that are sure to give your neighbors displacement envy. Here’s a list with 10 of the largest automotive engines available today.

10. Ferrari F12 TDF, 6.3-liter V12

First up, we start with Ferrari’s gargantuan 6.3-liter V12. In the ultra-high-performance F12 TDF, it puts out a Le Mans-grade 770 horsepower and 519 lb-ft of torque, revving to nearly 9,000 rpm. That’s enough kibbles and bits to propel this car to 60 miles an hour in less than three seconds. Color us amazed. Less powerful versions of this engines are also used in the GTC4 Lusso and F12 Berlinetta.

9. Audi A8 L W12, 6.3-liter W12

Audi’s flagship A8 sedan can be ordered with several different engines including a large-displacement W12. No, that’s not a typo, it really is a “W” configuration; think of it as two “V” engines joined together at a common crankshaft. Engineering intricacies aside, with direct fuel injection and more valves than we can count, it puts out 500 horses and 463 lb-ft of twist. With an eight-speed automatic transmission and quattro all-wheel drive, it can propel this extended-length sedan to 60 miles an hour in just 4.4 seconds.

8. Lamborghini Centenario, 6.5-liter V12

But how about something more exotic than a fancy four-door? Well, Lamborghini‘s Centenario looks about as fast as a NASA rocket and it ought to be able to out run one as well, thanks to a massive 6.5-liter V12 mounted midship. This dozen-cylinder unit puts out 759 horsepower and 507 lb-ft of torque, which is crazy! This engine is also offered in the Aventador where it makes slightly less power.

7. Chevy Silverado Heavy Duty/GMC Sierra Heavy Duty, 6.6-liter Duramax diesel

Another gigantic engine is found under the hoods of General Motors’ hard working heavy-duty pickup trucks. The company’s famed 6.6-liter Duramax diesel displaces a whopping 6.6-liters, that’s 403 cubic inches in old-school measure. But there’s nothing outdated about this engine’s performance. It delivers an impressive 397 horsepower and 765 lb-ft of tire-smoking torque.

6. Ford 6.7-liter PowerStroke diesel, Ram 6.7-liter Cummins diesel

Next up, a couple more diesels! The latest incarnations of both Ford’s PowerStroke and Ram truck’s Cummins engines displace 6.7 liters. Each one offers plenty of compression-ignition fury, though in different ways. The Ford uses a V8 configuration, while Cummins opted to put six pots in a row. In any event, the Power Stroke puts out 440 horsepower and 860 lb-ft of twist, while the mighty Cummins, in its most potent form, delivers a stable of 385 ponies along with with a best-in-class 900 lb-ft of basement-level torque.

5. Rolls-Royce Phantom – 6.749-liter V12

For maximum smoothness, engines are best when their cylinders can be counted by the dozen. Accordingly, Rolls-Royce’s Phantom packs a silken V12 under its aircraft-carrier-sized hood. This engineering masterpiece displaces 411.28 cubic inches (6.749 liters), just fractions of a cube less than the next engine on this list. In any event, this Rolls-Royce powerplant is unbelievably refined and plenty muscular, delivering 453 horses and 531 lb-ft of torque.

4. Bentley Mulsanne – 6 3/4-liter V8

Topping the Phantom’s epic V12 by the smallest bit is the Bentley Mulsanne’s “6 ¾-litre” V8 (that’s 411.92 cubic inches, if you’re curious). You know it’s something special when the displacement is listed in fractions … either that or it’s oozing haughtiness from every pore. Anyway, this traditional, overhead-valve two-by-four is force fed by twin turbochargers and, in the Mulsanne Speed, drivers 530 brake horsepower and an awe-inspiring 811 lb-ft of torque.

3. Ford E-Series commercial cutaway chassis, 6.8-liter V10

Thus far, we’ve covered several ultra-luxury and exotic machines, but plenty of commercial vehicles feature big-bore engines. Case in point: the antiquated Ford E-Series commercial cutaway chassis, which is sort of like a van with its ass-end chopped off. Curiously, you can get one of these hard working vehicles with a 6.8-liter Triton gasoline V10. This industrial-grade engine is good for a modest 305 horses and 420 units of twist, but hey, at least it’s big.

2. Hennessey Venom GT, 7.0-liter twin-turbocharged V8

Hennessey is a Texas-based tuning company and builder of super sporty vehicles. The brand’s Venom GT is the world’s fastest car, with a verified top speed of 270.49 miles an hour, which is quicker than the now-extinct Bugatti Veyron. But that’s not all this car’s got; the company estimates it’s good for 278 mph. To propel this heavily modified Lotus Exige to damn-near triple Benjamin Franklin velocity takes a lot of power, like, A LOT. Accordingly, this car features a 7.0-liter, twin-turbocharged V8 that delivers a whopping 1,244 horsepower with 1,155 lb-ft of axle-snapping torque.

1. Dodge Viper – 8.4-liter V10

And now we’ve come to the largest-displacement internal combustion engine on the automotive market today. It’s found under the long, undulating hood of Dodge’s venomous Viper. This Detroit-built American exotic is powered by a truly monstrous 8.4-liter V10 that’s good for 645 horsepower and 600 lb-ft of twist, the most of any naturally aspirated sports car engine in the world. Not too shabby for an engine with pick-up truck heritage and just two valves per cylinder.

    Well if you're going to include an after market Hennessey's Venom GT and all those diesel trucks, you may as well throw in some bulldozers and such. Or maybe some real production cars, like the ZL1 Camaro or the dodge Hellcats. Were we talking displacement or HP?

  • The Viper engine never had "truck" heritage. It was developed under the umbrella of Lamborghini in the late 80's when Chrysler owned lambo.
