Today, most automakers are shrinking their engines in the name of lower weight and better fuel economy. But some glorious cars and trucks still use the power of displacement. These are the vehicles with the biggest engines that you can buy new today.
Dodge's supercharged Hellcat motor might be what everyone talks about, but the Charger/Challenger Scat Pack's V-8 is bigger. This naturally aspirated mill displaces 6.4 liters (392ci) and makes 485 hp.
Ferrari went all out with the 812 Superfast, creating a 6.5-liter naturally aspirated V-12 that makes an astounding 789 horsepower and revs to 8900 rpms. It's one of the greatest engines ever made, and we hope it's not the last of its kind.
Of course, Ferrari isn't the only company to make a big naturally aspirated V-12. Lamborghini offers one in the Aventador, making 740 hp in the Aventador S and 770 hp in the Aventador SVJ.
For its top-dog 7-Series, BMW still offers a V-12. A 6.6-liter twin-turbo V-12 that makes 601 hp and 590 lb-ft of torque. It's not a full-on M car, but it accelerates like one.
The new Silverado HD comes with a 6.6-liter V-8 whether you chose gas or diesel. The gas V-8 offers 401 hp and 464 lb-ft of torque, while the diesel cranks out 445 hp and 910 lb-ft of torque.
The entry-level Rolls-Royce Ghost and its coupe and convertible counterparts, the Wraith and Dawn, use a BMW-sourced 6.6-liter V-12 that makes between 562 and 623 hp depending on application. It's more than enough for a big luxury car.
The Mulsanne is one of the most expensive cars on this list. It's more than $300,000 and the 6.75-liter turbocharged V-8 has the same displacement as the legendary Bentley V8s of old. Each of these engines is built by one technician at the rate of .
The 6.7-liter Cummins turbodiesel inline-six engine in the new Ram HD offers 1000 lb-ft of torque. It's the first truck to offer four-digit torque, a day we thought might never happen.
For years, both Rolls-Royce and Bentley used 6.75-liter V-8 engines. The 6.75-liter V-12 in the Phantom and the Cullinan pays tribute to that shared history, and makes a mountain of torque.
You can get a 6.7-liter Powerstroke turbodiesel in the 2020 Ford Super Duty, but there's an even bigger gas engine. It's a 7.3-liter pushrod V-8, the first new cam-in-block engine from Ford in years.
Everything about the Bugatti Chiron is extraordinary, including its 8.0-liter, quad-turbo W-16 engine. It makes 1500 hp and helps propel the big Bug to a top speed of 261 mph.
The Viper has been out of production since summer 2017, but we just don't have the heart to take it off this list. A road car with an 8.4-liter V-10 is our kind of absurd.
