INFINITI G Coupe Models/Series Timeline, Specifications & Photos

After seeing the roads filled with M-Performance, AMG-line, S-line and R-versions for the premium brands, Infiniti has decided to make its move and invent a department for sportier versions of its vehicles. This is how the IPL (Infiniti Performance Line) was born. Engineers tried to work their skill on the G37 Coupe and, in 2011, they showed what was suppose to keep up with BMW's 335i Coupe, Merc's CLK 350 or Audi's S5 Coupe. They did manage to get right behind them, but not that close.

The G37 platform was a very good one, it was also used for the Nissan 370Z, but with all the heavy features installed as standard on the IPL, it was harder to keep up with the big boys. Japanese engineers worked hard and squeezed more ponies from the 3.7-liter V6 engine. They obtained 348 hp and 374 Nm (276 lb-ft) of torque. Standard transmission was a 6-speed manual and a 7-speed automatic was offered as an option.

The options list for the G37 IPL had only two button-checks: color and transmission. Everything else was fitted as standard, including navigation, heated seats, XM radio, power-seats, sunroof and light-alloy-wheels.

Performance wise, the car was quick, with a 0-100 kph (0-62 mph) sprint in 5.8 seconds and a top speed of 270 kph (168 mph), which was more than the other germans premium coupes, limited to 250 kph (155 mph).

Infiniti introduced in 2007 a new performance coupe built as a successor for the already aged G35.

With the G37 Coupe, Infiniti managed to create a vehicle that was more than just a two-door version of the G37 Sedan. Instead, it shared the platform with Nissan 350Z and 370Z and Infiniti's M, EX, and FX models.

It was a mix of GT and sports car from the outside, with a long hood and arched, slope-down rear end. At the front, the boomerang-style headlights flanked the chrome-surrounded grille with horizontal slats. The apron hosted a wide center air intake and two side scoops needed to cool the front disc brakes.

The interior was more refined than on the G35, and it featured better materials, with a leather-wrapped steering wheel and gear selector. Still, despite being introduced in late 2007 at the New York Motor Show, it featured an old-school infotainment system with a control panel placed under the display and no touch-screen feature. The carmaker tried to convince its customers that it was better, but time showed that it wasn't. At the front, the high-bolstered bucket seats provided excellent lateral support, while at the back, the bench was too cramped for adult-sized occupants and with virtually no legroom.

Under the hood, the carmaker installed a 3.7-liter V6 with variable valve technology and sent the power to the rear wheels via a seven-speed automatic gearbox. A welcome feature was the all-wheel-steering on the G37, which improved the car's handling.
