The Largest Engines Currently On Sale

Gas prices are high as hell right now. While the national average price of a gallon of regular gas is down just a bit, it remains just a cent away $5.00/gallon. The average prices are even worse when you get down to the state and local levels. Here in California, the average is $6.37.

Yet, none of this has had any heavy influence on automakers or keeping them from debuting or selling powerful gas-guzzling engines. In fact, cars have never been more powerful. And these cars listed here have the most powerful, largest engines currently on sale ranked from the very biggest, to the not-so-big.

All engines here are only 5.0-liters and up.

While a Bugatti may just be a rolling symbol of excess, you can't argue with the engineering marvel that is its W16: 8.0-liters, four turbochargers, 1,600 horsepower (at least in the case of the Chiron Super Sport), and the ability to propel the Chiron to speeds in excess of 300 mph on the limited edition Chiron Super Sport 300.

The appropriately named 'Godzilla' engine, Ford introduced the 7.3-liter gas V8 in 2020 as a replacement for its long-running V10. It's currently the largest engine you can option in a pickup, available on Ford's Super Duty F-250 and F-350 pickups. You'd think with its size it would have a bit more power though. I'm in no way saying this V8's 430 hp and 475 lb-ft of torque are on the shy side, but... it's fine. The 7.3-liter V8 is a $2,045 option on certain trims.

Rolls Royce still uses BMW engines (which makes sense as BMW owns the company). One of their potentially oldest engines manufactured, the 6.75-liter V12, is used in the new Phantom that debuted back in 2018. It was reengineered a bit, bearing the code N74B68. that V12 in not only used in the Phantom, but also the Cullinan, and Ghost.

The Cummins I6 has been a mainstay in the Ram lineup since it was a Dodge. It's always been a monster of an engine; even in 2003 it was making 650 lb-ft of torque. When the dick-measuring one-upmanship heavy-duty truck wars of the late 2010's happened, Ram emerged on top with the 6.7L once again. The Cummins currently makes 420 hp and an insane 1,075 lb-ft of torque. It's not cheap either, as it's a $12,395 option on Ram's 2500 and 3500.

If you've got a hankering for 6.6-liters of something powerful, GM will happily oblige. The company offers two different 6.6-liter engines that are available in various trims/models of its truck and van offerings. There's the 6.6-liter gas V8 that produces 401 hp. If that's not powerful enough, there's a 6.6-liter turbodiesel V8, but is only available in heavy duty trucks. Putting out 445 hp, the torque is where it's at, with a stump-pulling 910 lb-ft of torque.

Take a good, long look because this is the last time you'll see a v12 in a BMW, unless you go over to Rolls Royce. Only used in the M760i, this 6.6-liter V12 is a variant used in the Rolls Ghost, Wraith and Dawn. It makes 601 hp in the 7 Series.

Only available on the limited production Aventador LP 780-4 Ultimae, this screaming V12 develops 769 hp.

You're looking at one of, if not the last Ferrari V12. Used in the 812 GTS, this monster engine develops 788 hp. Thats enough to propel the coupe to 60 mph in just 2.8 seconds and on to a 211 mph top speed.

Originally only available as a crate engine in the mid 00's, Chrysler put the 6.4-liter V8 into production in 2011 with the Challenger SRT8. From then on it was available on Chargers and Challengers equipped with special edition packages.

In 2014 Ram used the 6.4-liter for Ram Heavy Duty models, though this engine only differed in that its tuned for truck duty and towing capacity. From 2015 and on, it became the standard engine for the Scat Pack models. It was also used in the Jeep Grand Cherokee SRT, Dodge Durango SRT and more recently, the Jeep Wagoneer and Wrangler Rubicon 392.

Probably one of the best V8's GM has ever made, this 6.2 supercharged V8, which has been the company's go-to performance engine for multiple models, in a couple of iterations. You'll be familiar with the Blackwing family of performance cars, like the CT5-V and upcoming Escalade-V. Another iteration is used in the Chevy Camaro ZL1.

The most powerful production muscle car, the 6.2-liter supercharged Hemi V8's used in the Dodge Demon and Hellcat models were literal monsters. No one will ever fully use the 707 and 807 hp these things came with.

I know you're probably thinking "I thought you already listed GM's V8?" Nope. The C8 Corvette gets its own specific V8 in the 6.2-liter LT2 V8. This NA V8 makes 490 hp.

Bentley has been downsizing over the last few years. While its crosstown rival Rolls Royce is still fine with using huge 12 cylinder engines, you'll only find one 12 cylinder engine in use on two models at Bentley: the Continential GT Speed models. The 6.0-liter VW derived W12 makes 650 hp which is enough to propel this 5,000+ pound coupe to 60 mph in just 3.5 seconds.

This will likely be the last V12 engine you'll ever see in a Mercedes Benz (unless they debut some kind of uber Maybach SL), and it's only available in the opulent S-Class Maybach. Handmade with twin turbos, it makes 621 hp.

The 5.7-liter Hemi V8 has been a Chrysler mainstay since the introduction of the LX cars in the mid-2000s. Originally rated at 345 hp, the current engine in use in the Chrysler 300C and everyDodge model that wears an R/T badge is rated at 363 hp in the 300 while Dodge models get 370 hp. No matter the power output, each 5.7L gets a cylinder deactivation feature for better fuel economy.

Only used in the Infiniti QX80, Nissan Armada (which Nissan didn't give to us until years after everyone else had it) and the truck no one pays attention too, the Titan, its the biggest engine Nissan makes. It makes 400 hp and 413 lb-ft of torque.

GM uses this engine in everything from the GMC Sierra to the Chevy Tahoe. The 5.3-liter Ecotech V8 has been tuned for more fuel efficiency, offering two different versions of cylinder shutoff systems depending on which trim of vehicle you get.

Another of the "last of "engines, this is Aston's final V12. Used in the DBS Superleggera and limited edition (and sold out) V12 Vantage, this twin-turbocharged V12 makes 690 hp in the V12 Vantage and 715 hp in the DBS Superleggera.

This V8 makes this Shelby GT500 the most powerful Mustang ever built. Hand built by Ford Performance, this supercharged flat-plane crank V8 puts out 760 monsterous hp and 625 lb-ft of torque.

This engine is the quintessential V8 engine for the Jaguar/Land Rover lineups and has been for years. Currently, you can find it under the hood of everything from the Jaguar F-Type to the Land Rover Defender, and nearly every Range Rover model. The engine is offered in both NA and supercharged variants.

Known internally as the 2UR-GSE, this naturally aspirated V8 is the go-to engine for Lexus and its performance models. Its seen use in every F performance model since the original IS F and also sees duty in the LC 500 luxury GT. Outside of the Lexus GX and its ancient 4.6-liter V8, it's also the only other V8 you can get from Lexus.

Introduced on the 2011 Mustang as a replacement for the aging 4.6-liter V8, the Coyote V8 makes 450 hp in the Mustang GT. You can also have it in the F-150 where, if you equip it in a regular cab model, you can have a pretty decent sport truck for just over $40,000.
