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 and the "392 HEMI" logo, which gives the engine a unique, clean and aggressive look.
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 shifting schedule.
► 2012 Dodge Charger SRT8 on the track
New for the 2012 Charger SRT8 is the 470 horsepower 6.4-litre HEMI®
V8 that features 45 more horsepower and 50 more
lb.-ft. of torque across a significantly wider rpm range, new Exhaust system technology for improved fuel
efficiency, along with new paddle shift technology and adaptive damping
suspension for optimal driver control.
Performance numbers for the 2012 Dodge Charger SRT8 include 0-96 km/h (0-60
mph) acceleration in the high 4-second range; quarter mile in the high
12-second range; 0-160-0 km/h (0-100-0 mph) in less than 16 seconds; top
speed of 282 km/h (175 mph) and stopping power from 96-0 km/h (60-0 mph) in
37metres (120 feet).
Under the hood, the new 6.4- litre HEMI® V8 delivers more horsepower and torque than
the 6.1-litre HEMI V8 it replaces -- up 11 per cent to 470 horsepower (351 kW) and up
12 per cent to 470 (637 N•m) lb.-ft. of torque.
First Drive ► 2015 Audi RS7 Sportback
The headlights, also adapted to the new Singleframe, come with LED
technology as a standard feature. On request, Audi provides the headlights
with the innovative Matrix LED technology, available exclusively on the RS
7 Sportback with additionally darkened trims. This offer also includes turn
signals with dynamic display at the front. At the rear they are generally
standard. The tail lights also have a new interior design. New to the paint
finishes are the colors Floret Silver, metallic; Glacier White, metallic;
Mythos Black, metallic and Sepang Blue, pearl effect.
In the elegant black interior, dominated by the RS sport seats, the
designers have discreetly revised the instrument cluster: the air outlet
controls of the vent nozzles, the shift paddles behind the steering wheel
and the quattro emblem on the instrument panel. The standard MMI navigation
plus with MMI touch now uses the modular infotainment platform of the
latest generation; its highlight is an efficient graphics processor from
Audi's partner, Nvidia.
The 4.0 TFSI in the revised Audi RS 7 Sportback provides as before 412 kW
(560 hp), with a constant 700 Nm (516.3 lb‑ft) of torque at engine speeds
between 1,750 and 5,500 rpm. The engine catapults the five‑door coupé
from 0 to 100 km/h (62.1 mph) in 3.9 seconds; the optional dynamics
packages allow top speeds of 280 and 305 km/h (174.0 and 189.5 mph),
respectively. In the ECE cycle however, the resonant V8 bi‑turbo needs only 9.5 liters of fuel per 100
kilometers (24.8 US mpg) with 221 grams CO2 per kilometer (355.7 g/mi). A
key factor in this efficiency is the cylinder on demand (COD) system, which
can shut down four cylinders during partial load operation.
An eight‑speed tiptronic tuned for sporty performance, with a tall eight
gear, directs the power of the eight‑cylinder engine to the quattro
permanent all‑wheel drive. On request, Audi will combine quattro
all‑wheel drive with the optional sport differential on the rear axle.
The RS adaptive air suspension, together with adaptive damping, standard on
the RS 7 Sportback, lowers the body by 20 millimeters (0.8 in); its control
is incorporated in the Audi drive select driving dynamics system. Audi
offers the tauter RS sport suspension plus with Dynamic Ride Control (DRC)
as an alternative. A further option is dynamic steering, with its
continuously variable steering ratio.
The revised Audi RS 7 Sportback is fitted with 20‑inch forged lightweight
alloy wheels as a standard feature; 21‑inch cast aluminum wheels in three
color versions are optionally available. The four internally ventilated
brake disks have a weight‑saving wave design; alternatively Audi installs
carbon fiber-ceramic disks. Electronic Stabilization Control (ESC) has a
Sport mode that can be deactivated altogether if need be.
The Audi RS 7 Sportback can be ordered in Germany from the 3rd quarter
2014. Its base price is €113,300.

First Drive: 2015 Dodge Charger SRT Hellcat 707 hp
The new 2015 Dodge Charger SRT Hellcat is powered by the new supercharged
6.2-liter HEMI V-8 engine. Its 707 horsepower matches the
highest rating of any V-8 engine in Chrysler Group’s celebrated history.
The all-new supercharged V-8 engine is mated to the beefy new TorqueFlite
8HP90 eight-speed automatic transmission.
This new Hellcat engine is Dodge and SRT’s first application of V-8 Supercharger technology, featuring a
forged-steel crankshaft with induction-hardened bearing surfaces. The
result is a crank so well-engineered it can withstand firing pressures of
110 bar (1,595 psi) – the equivalent of five family sedans standing on
each piston, every two revolutions. And its unique, specially tuned crank
damper has been tested to 13,000 rpm.
High-strength, forged-alloy pistons, developed using advanced telemetry
measurement, are coupled to powder-forged connecting rods with
high-load-capacity bushings and diamond-like-carbon-coated piston pins.
The supercharged 6.2-liter HEMI V-8 has premium-grade, heat-treated
aluminum-alloy cylinder heads, which are optimized for superior thermal
conductivity. And its die-cast aluminum rocker covers are HEMI Orange.
Standard on the Charger SRT Hellcat is the largest front-brake package ever
offered in a Chrysler Group vehicle, which were first introduced on the
2015 Challenger SRT Hellcat, featuring all-new 390-mm (15.4-inch) Brembo
two-piece rotors with six-piston calipers for outstanding heat management
and thermal capacity and longevity.
The unrivaled four-door performance numbers tell an impressive story with
the quarter mile in 11.0 seconds, 0-100-0 mph in under 13 seconds, and a
top speed of 204 mile per hour (mph).
The 2015 Charger SRT Hellcat’s restyled driver-focused interior features
premium, soft-touch materials, a new 7-inch thin-film transistor (TFT)
customizable digital instrument gauge cluster and a new instrument panel
center stack with the latest generation 8.4-inch Uconnect touchscreen media
New for 2015, drivers can select one of the many offered backgrounds to
connect the digital look and feel with their chosen interior package. In
addition, the Charger SRT Hellcat comes standard with a premium 900 watt,
18-speaker Harmon Kardon audio system.
An all-new and class-exclusive electronic shifter with an all-new
driver-oriented T-handle provides the driver with intuitive gear selection
and offers an Auto Stick selector gate for added control.
The 2015 Dodge Charger SRT Hellcat will be built at the Brampton (Ont.)
Assembly plant. Production is slated to begin in the first quarter of 2015.
