The Street and Racing Technology (SRT) performance engineering team builds upon the all-new 2011 Chrysler 300 sedan already executed for a world-class luxury experience, to deliver Chrysler's most powerful and best handling model ever.
Performance numbers include 0-60 mph acceleration in the high 4-second range; quarter mile in high 12-second range; 0-100-0 mph in less than 16 seconds, top speed of 175 mph and stopping power from 60-0 mph in 120 feet.
The return of the 300 SRT8 to the Chrysler lineup in 2012 evokes a strong comparison to the original high-performance production car of its time -- the 1955 Chrysler 300. Known for simple, strong lines, excellent engineering, high levels of luxury and outstanding performance with the first modern American V-8 engine to produce 300 horsepower, the first Chrysler 300 (C-300) was styled by Virgil Exner, who radically redesigned the entire Chrysler line and created what they called "The Forward Look" in 1955. Without much chrome on the sides, his designs were simple, but strong. Exner is credited with creating the illusion of fast, forward movement.
Under the hood of the 2012 Chrysler 300 SRT8, the new 6.4-liter HEMI® V-8 makes its debut in the Chrysler brand product lineup delivering 470 horsepower (351 kW) and 470 (637 N•m) lb.-ft. of torque, up 45 horsepower and 50 lb.-ft. over the 6.1-liter HEMI V-8 it replaces.
The improved torque output -- including an additional 80 lb.-ft. at 2,900 rpm -- allows for inspired standing starts and improved straight-line performance while new, performance-tuned motor mounts improve idle stability and ride control at any speed. An active intake manifold and high-lift camshaft with cam phasing provides maximum low-end torque while optimizing high-end power.
► 2012 Dodge Challenger SRT8 392 on the Track
The 392-cubic inch (6.4-liter) HEMI® V-8 delivers 470 horsepower (351 kW) and 470
(637 N•m) lb.-ft. 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.
A look under the hood reveals unique valve covers with painted silver ribs

The 2012 Dodge Challenger SRT8 392 features a standard Tremec TR-6060
six-speed manual transmission and a dual-disc high performance clutch -- a
proven performer that was first offered on the 2008 Dodge Viper SRT10®.
The optional five-speed automatic transmission features new, standard
steering wheel mounted paddle shifters that join the center console mounted
Auto Stick, allowing for a choice of spirited shifting on both the road and
the race track. Both methods give the driver the ability to manually select
specific gears on the transmission.
In "Drive," the transmission controller will automatically shift the
vehicle. The aggressiveness of the shifting is defined by the mode chosen -
either "Normal" or "Sport." Fully adaptive electronic control of all
shifting makes the powertrain more responsive while minimizing harshness.
In "Manual," the shift method is defined by the driver choosing to use
either paddle shift or Auto Stick. The "Sport" mode adds a hold function to
the calibration in all gears, allowing the driver full control of the
► 2012 Porsche Panamera TURBO S (550 hp) on the road
The new Panamera turbo S is a unique
combination of performance and efficiency, driving dynamics and comfort.
The 4.8 litre, V8 biturbo charged engine
delivers 550 hp (410 kW), ten percent or 50 hp (37 kW) more than the
already very powerful engine in the Panamera turbo. By the same token, the torque also
increases from 700 to 750 Nm. In the "Sport" and "Sport Plus" mode of the
standard Sport Chrono Package turbo and
during kick-down in normal mode, the eight cylinder engine delivers fully
800 Nm with the so-called overBoost
The power pack is behind the new top-of-the-range Panamera's record sprint
times. Thanks to Launch Control, 100 km/h (62 mph) is reached in 3.8
seconds; the top speed is 306 km/h (191 mph). Despite the increased
performance, fuel consumption remains at the moderate level of the Panamera
turbo -- yet another example of "Porsche
Intelligent Performance". In the NEDC the Gran Turismo covers 100
kilometres (62 miles) on 11.5 litres of fuel. Fuel consumption falls to
11.3 litres per 100 km (25 mpg imp.) when fitted with the 19 inch,
all-season tyres with optimised rolling resistance developed for the
Panamera by Michelin.
The increased performance compared with the Panamera turbo can be attributed to two main enhancements:
Improved turbochargers with
titanium-aluminium turbine wheels and modified engine control. The use of
the innovative titanium-aluminium alloy reduces the weight of the turbine
and compressor wheel. This results in a lower moment of inertia and thus in
improved and more agile engine responsiveness.
Even for a top luxury class model, Porsche's new top-of-the-range Panamera
boasts an extraordinarily comprehensive equipment level. In keeping with
the sporty concept of the high-performance Panamera, it features the most
important driving dynamics control systems as standard. For example,
Porsche Dynamic Chassis Control (PDCC), an active roll stabilisation
system, nips in the bud the vehicle's tendency to lean when cornering, thus
enhancing agility and comfort in equal measure. Porsche Torque Vectoring
Plus (PTV Plus) applies a variable torque split to the rear wheels combined
with an electronically controlled rear differential lock, thus ensuring
superior traction and therefore greater agility in every driving situation.
The steering system uses the speed-dependent Servotronic. The Sport Chrono
Package turbo, which tunes the
suspension and power unit, making them even sportier by pressing the
additional "Sport Plus" button, is also fitted as standard, as is the
sports Exhaust system for an even more
emotional engine sound.
The sporty character of the new Panamera turbo S is apparent not just in its performance
but is also reflected on the exterior. The 20-inch turbo II wheels with increased rear axle track
width, side skirts from the Porsche Exclusive range and the adaptive
extending four-way rear spoiler in the exterior colour ensure particularly
sporty performance and look. The fusion of exclusivity and sportiness is
conveyed in the interior by the bi-colour leather finish, fitted as
standard. The new combination of black/cream is offered exclusively for the
new Panamera turbo S with agate
grey/cream also being added as an exclusive combination from the autumn.
The Panamera turbo S costs 167,076 euro
in Germany, including VAT and country-specific equipment. Deliveries start
in June 2011.
