DETROIT (Jan. 14, 2014) – Want power, precision and passion? Lexus
revealed its most powerful V8 engine in the all-new 2015 RC F
performance coupe at the North American International Auto Show in
Detroit. The F performance model, based on the RC coupe, gets its
powerful roar from more than 450 horsepower and more than 383 lb.-ft.
torque.

To get that amount of power efficiently to the ground the RC F will
make use of a Torque Vectoring Differential (TVD) to ensure remarkable
handling and performance. The power will transfer through a newly
calibrated eight-speed Sports Direct Shift (SPDS) transmission with
paddle shifters.

"I've built RC F to be enjoyed by all enthusiasts – no matter
what their level of expertise," said RC F chief engineer Yukihiko
Yaguchi.

"There's a misconception that racing cars are hard to drive. In
fact, they're easy in the right hands because they've been
purpose-built for the skill level of their drivers. It's the same with
RC F.

"Electronics can be modified instantly on board to provide
appropriate levels of performance and protection. But even at its
basic setting, it's a blast."

Driving Dynamics with More Power and Usability
The RC F has an all-new 5.0-liter 32-valve V8 engine that will provide
increased maximum power at higher engine rpm than previously possible.
For the first time in a Lexus performance engine, the RC F uses the
Atkinson cycle at cruising speeds for enhanced fuel economy and then
switches to the Otto cycle at higher rpm to develop impressive
performance levels.

Driver engagement has been made possible by purpose designed sound and
power delivery. A uniquely tuned eight-speed Sports Direct Shift
(SPDS) transmission improves linear throttle response.

It helps the driver control the torque and power precisely as it is
applied.

The newly calibrated VDIM adds a vertical G-sensor to provide greater
vehicle stability

Torque Vectoring Differential
The RC F uses a Torque Vectoring Differential (TVD), a first in a
Lexus, to increase driving performance. It has three operating modes:

Standard for a balance of nimble performance and stability;
Slalom for emphasis on nimble steering response; and
Track to help with consistent stability, ensuring the vehicle stays on
the intended corning line as the driver applies more throttle.


Handling
The foundation for the vehicle's mechanical grip is the highly rigid
body with large cross-section rocker panels and a very stiff front
lower brace. Specialized Lexus manufacturing techniques are also used,
including body adhesives, laser-screw welding, laser brazing and
multi-spot welding. Grip is further enhanced through use of a wider
tire and wheel assembly.

RC F has front and rear coil-spring independent suspension, with
monotube gas-filled shock absorbers and ball-jointed stabilizer bars.
Unsprung weight is reduced by the adoption of three new 19-inch
diameter forged aluminum wheels which minimize tire/wheel assembly
mass and maximize rigidity.

Exterior Design
Lexus RC F adds to the stylish body of the new RC coupe on which it is
based. The RC F features its own version of the Lexus signature
spindle grille which dominates the front of the vehicle from hood line
to lower lip. The grille has a subtle F-mesh pattern on the lower
half.

In profile view RC F has a unique front hood which raises the peak of
the vehicle, creating a powerful side view.

The RC F takes design cues from the Lexus LFA supercar, especially in
essential air cooling and aerodynamics. Its hood air vent, such as
those on the LFA, combined with front cooling ducts contribute to
engine cooling and overall vehicle stability.

As in the LFA, an active rear spoiler is incorporated into the trunk
lid to provide down force at speeds of more than 50 mph. The active
spoiler is a highlight of RC F's aerodynamic package which includes
careful tuning of the underbody, the intakes in the grille and the
front fender vents, and strategic placement of the aero stabilizing
fins.

To the side, front fender ducts in the shape of an L also aid cooling
performance while adding to the aggressive stance.

The RC F's available carbon fiber package offers a clear coated carbon
fiber roof and active rear spoiler drawn from the LFA production
experience.

Interior Design
Uniquely designed components, including combination meters, the
steering wheel, seats, ornamentation and pedals, convey a sense of
connection with the driver that only a Lexus F performance model can
achieve.

RC F's all-new combination meters are further developed from LFA while
also referencing aircraft cockpit instruments. The meters provide a
wide range of easy to read information for the various drive modes.

The combination meters include a large centrally mounted tachometer
that alters according to drive mode, digital and analog speedometer,
differential torque vectoring monitor, G-Force meter, oil and water
temperature gauges, mileage information and a stopwatch.

The driver's connection to the RC F is paramount. The RC F debuts a
Lexus-first elliptical cross-section thick grip steering wheel for
greater control during performance driving. The placement, shape and
operation of paddle shifters make it easier to change gears on the
track and in other performance circumstances.

The all-new high back seats have been designed for exceptional holding
performance. An integrated foaming technique creates a highly
supportive and taut fitting seat with trim material that stays fixed.
