Infiniti has officially introduced its latest IPL G Convertible at the 2011 Los Angeles Auto Show.

Infiniti has expanded its performance-minded IPL line to include the company's G Convertible. The 2013 IPL G Convertible will join the IPL G Coupe in Infiniti showrooms during the spring of 2012.

Based on the G37 Convertible, the IPL G Convertible features a number of subtle design and performance tweaks intended to transform the drop top into a crisper driving machine.

Although exterior changes are minimal, the IPL G Convertible sports a unique front fascia with integrated fog lights and black finishers, sculpted side sills and chrome-tipped exhaust outlets. The IPL G Convertible comes with unique 19-inch wheels finished in graphite and just two paint colors are available - Moonlight White and Malbec Black.

That limited color palette carries over to the G's interior, with only two choices on the options list - Stone and IPL-exclusive Monaco Red. No matter the color selected, the IPL G Convertible comes with red-stitched sports seats with embroidered IPL logos.

On the performance side, Infiniti engineers have tuned the G's suspension and engine to return a more sporting driving experience. The IPL G Convertible's front spring rates have been increased 14 percent over the G Convertible Sport model and rear spring rates increased 4 percent. Front stabilizer spring rates are also up - increasing by 6 percent up front and 125 percent out back. Infiniti says it has also adjusted the car's shock tuning.

Underhood the G37's 3.7L V6 remains, but power has been increased through improvements to the engine's intake and exhaust. Power for the IPL G Convertible stands at 343 horsepower - an improvement of 18 horsepower - and 273 lb-ft of torque, marking an improvement of 6 lb-ft.

All 2013 IPL G Convertible models will shift through a seven-speed automatic transmission.

No word on pricing, but expect something north of the $50,000 mark when the IPL G Convertible rolls into Infiniti showrooms next year.
