Engine and Transmission
Based on the premium foundation of the Infiniti G37 Convertible, the IPL G
Convertible features an advanced VQ37VHR 3.7-liter V6. The engine management
system has been recalibrated through air-fuel mixture and ignition timing
optimization, raising the maximum horsepower output point to 7,400 rpm. To
obtain a natural acceleration feel, the torque curve from low revs to the
maximum torque point (5,200 rpm) was tuned for linearity. The IPL-tuned
high-flow exhaust is a full dual exhaust design with independent left and right
large diameter pipes. The muffler's inner structure and materials have been
maximized to reduce pressure and provide an appropriate performance exhaust
note. The result is a 30% reduction in exhaust pressure versus a base G
Convertible's Y-pipe exhaust system design.
As a result of both the exhaust system and engine management changes, the IPL G
Convertible generates 343 horsepower - an increase of 18 horsepower over the
non-IPL models - and 273 lb-ft of torque (+6 lb-ft).
The engine is matched to an electronically controlled 7-speed automatic
transmission with Downshift Rev Matching and quick-shift Drive Sport (DS) mode
with magnesium paddle shifters and Adaptive Shift Control (ASC).
IPL G Convertible's Chassis and Suspension
The IPL G Convertible's enhanced dynamic vehicle performance focuses on
providing confident handling, flat ride and smooth ride comfort. The IPL
suspension tuning and damping management philosophy is designed to optimize each
aspect of the suspension, effectively connecting the driver to the road surface
while minimizing uncomfortable vibrations. Front spring rates have been increase
14% over the G Convertible Sport model and rear spring rates increased 4%. Front
stabilizer spring rates have been increased 6% over the G Convertible Sport
model and rear stabilizer spring rates increased 125%. Shock tuning has also
been adjusted and incorporates an all-new HF-type shock.
The IPL G Convertible also offers a sport-tuned steering gear and large 4-wheel
sport brakes (14-inch front, 13.8-inch rear) with aluminum-alloy opposed
calipers (4-piston front/2-piston rear).
