Lexus RC F
Want power, precision and passion? Lexus revealed its most powerful V8
engine in the all-new 2015 Lexus RC F performance coupe at the 2014 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 Lexus 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 Lexus 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 Lexus 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.
Lexus 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 Lexus 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 Lexus 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.
Lexus 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 Lexus 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.
