Checking the engine
Components expected to operate at high speeds have been made as light and
precise as possible, realizing a superfast engine capable of revving from idle to 9,000
rpm in only 0.6 seconds.
In order to ensure adequate lubrication under high G-loads, a dry sump lubrication
system has been adopted.
The engine oil is cooled by a liquid-cooled oil cooler located in the valley between
each bank of cylinders and an air-cooled oil cooler housed within the front overhang.
In addition, two high-per formance radiators have been housed within the rear
overhang for an optimal front-rear weight balance.
A TFT LCD panel has been adopted to accurately transmit various information from
the engine to the driver. An analog-style digital tachometer displays engine speed
while other real-time engine information is displayed digitally for both superior visual
clarity and response.
An acrylic lens with a metal ring is positioned at the center of the meter to clearly
display the primary instruments and to create a three-dimensional appearance.

Maintaining the vehicle’s exterior
When washing the vehicle, be careful not to
touch the hood grilles, bezels in the radiator
grilles, or exhaust pipes and surrounding
area until they have cooled sufficiently, as
these components may cause burns.

• Do not apply water to the inside of the engine compartment. Doing so may cause the
electrical components etc. to catch fire.
• Do not flush water over or into the hood grilles (especially the arrowed portion in the
illustration).
• Do not flush water over or into the exhaust pipes and surrounding area or the bezels in
the radiator grilles until they have cooled sufficiently.
When using a high-pressure washer
• Do not aim the head of the nozzle at the hood grilles or radiator grilles. Doing so may
negatively affect the engine or cause a malfunction in the electric cooling fan motors that
may result in overheating.
• Do not allow the nozzles of the car wash to come within close proximity of the windows
or rear hatch.
Do not use automatic car washes as they may scratch the vehicle body and damage
the paint.
