HEMI V8 Engine
The 392-cubic inch (6.4-liter) HEMI V-8 delivers
470 horsepower (351 kW) and 470 lb-ft (637 Nm) of torque. The torque band is
extremely flat allowing for strong standing starts and improved straight-line
performance throughout the rpm range. An advanced active intake manifold along
with high-lift cam with phasing provides maximum low-end torque and high-end
power while still delivering up to 23 miles per gallon on the highway with the
standard manual transmission. Performance-tuned engine mounts improve idle
stability and ride control at all speeds.
Standard Fuel Saver Technology
(four cylinder mode) in automatic transmission equipped models allows the engine
to operate economically on four cylinders or use the power of all eight
cylinders when needed. The EPA fuel economy miles per gallon (mpg) (City/Hwy)
ratings for the 2012 Dodge Challenger SRT8 392 are 14/22 for automatic
transmission models and 14/23 for manual-transmission models.

The Ready Alert Braking system anticipates when the driver quickly
releases the accelerator pedal and may initiate an emergency brake stop, after
which the electronic stability control pump engages to set brake pads against

Improved brake cooling and fade performance comes courtesy of wind-tunnel
designed brake cooling ducts that direct airflow to the vented rotors for
consistent stopping power.

392's Storied History
The original 392
HEMI engine was introduced in the new 1957 model year Chrysler and Imperial
products. It replaced the 354 cubic-inch version of the original HEMI launched
in 1951.Compared with the 354 engine, the 392 was completely revised and
improved, with larger valves and ports, a beefier block and crankshaft and
improved bearings. In short, the 392 HEMI, often affectionately referred to
simply as the "92," was perfect for drag racing.
More than a few racers
at that time immediately enhanced the performance of the newest HEMI by bolting
on six or eight carburetors, installing new camshafts, etc., and went racing.
Racing legend Don 'Big Daddy" Garlits ran a 392 in his infamous Swamp Rat I
dragster at record speeds of faster than 180 mph on nitro with no supercharger.
Garlits also used a 392 HEMI to officially break the 200-mph barrier when his
Swamp Rat went 201.34 mph at Atco, N.J., in 1964.
But the 392's success
went beyond the drag strip. It also set records at the Bonneville Salt Flats and
in boat racing. Drag racing boats were no different than their land-based
counterparts in the use of the 392. Famous HEMI engine builder Keith Black was
better known on the water than on the land, until he teamed up with Tommy Greer
and hired Don "The Snake" Prudhomme to dominate Top Fuel in California in the
early 1960s using a 392 HEMI.
After 1958, the 392 HEMI was gone as a
production engine, but it still remains a legend. Collectors are now preserving
many historic 392-powered race cars and hot rods and proudly displaying them on
show car circuits.
In 2007, Mopar - Chrysler Group LLC's service, parts
and customer-care brand - helped celebrate the 50th anniversary of the original
392 by launching a modern, crate engine version of the 392 HEMI.
