Infiniti working on 530-HP twin-turbo IPL model for G

We certainly like the idea behind the Infiniti Performance Line, but execution has left us largely underwhelmed. Instead of an M or AMG fighter, buyers are left with little more than fancy paint and a stiffer suspension. But according to Motor Trend, Infiniti may have something more impressive brewing.

An unnamed source spilled the goods on the future of the G line, including a juicy detail about a hyper performance coupe. The next-generation G is set to hit the market during the summer of 2014, bringing with it a rash of changes.

One of those is the introduction of an IPL-specific 3.7-liter V6. The source claims the engine is all-new and features direct-injection and two turbos to help it produce a whopping 530 horsepower. This time, it seems Infiniti has its heart set on stepping up to the Mercedes-Benz C63 AMG and BMW M3. The engine will be built in Japan alongside the powerplant for the Nissan GT-R.

Now for the bad news. The shadowy source says the high-performance IPL will be priced in line with the GT-R, at least in Japan. On this side of the globe, the brawny Nissan commands a price well north of the $58,930 MSRP on the C63 AMG, which leads us to believe there's still some pricing to be sorted out on that front.
