6.2L HEMI Hellcat V8 Among Ward's 10 Best Engines

"A 707-hp engine in a car starting at less than $60,000 is an achievement all by itself, but what impressed WardsAuto editors beyond the V-8's prodigious output, diamond-coated washers, extra-strong alloy pistons and all the other extras that went into engineering this masterpiece, is how civilized the beast is in ordinary driving," Winter said. "It's easy to make a street-legal race car, but it is a major accomplishment to make such a powerful engine a pleasure to drive to the grocery store as well as at the track."

The HEMI Hellcat, with 91 percent new content compared with the 392 HEMI, is the heart and soul of the 2015 Dodge Challenger SRT Hellcat, which starts at $59,995, and its stablemate, the Charger SRT Hellcat -- the quickest, fastest, most-powerful sedan ever, boasting a certified quarter-mile clocking of 11 seconds and a top speed of 204 mph. Its starting U.S. MSRP is $62,995.

Accordingly, the HEMI Hellcat's engineering is, in a word, extreme. Consider:

* Its forged-steel crankshaft is so well-engineered it can withstand firing pressures of 1,595 psi (110 bar) -- the equivalent of five family sedans standing on each piston, every firing event
* Its twin-screw supercharger, which has polymer-coated rotors, boasts a drive ratio of 2.36:1 and a maximum speed of 14,600 rpm
* A low-temperature cooling circuit with two air/coolant heat exchangers integrated into the supercharger housing, keeps charged air temperatures below 140 degrees Fahrenheit (60 degrees Celsius) while enabling air flow of up to 30,000 liters per minute
* Its power is not de-rated due to cooling demands, even after 20 minutes of a hard driving on a road course at an ambient temperature of 100 degrees Fahrenheit (37 degrees Celsius)
* Eight injectors served by half-inch fuel lines, each capable of delivering a flow rate of 600 cc/min; can drain the fuel tank in approximately 13 minutes at full power

And, of course, its block is HEMI Orange.
