Although long denied by Nissan CEO Carlos Ghosn, AutoExpress is reporting that Nissan is readying a stretched version of it's GT-R supercar.

The 4-door variant is to have 4-doors and instead of featuring the GT-R's 3.8L turbocharged V6, the Infiniti model would get a version of FX50's 5.0L V8. It would come standard with the rest of the GT-R drivetrain including it's rear mounted transaxle and all-wheel drive. They're expecting horsepower to be about 420 and 0-60 time in the low 5-seconds. The model would be a reincarnation of the discontinued Q line and would go head-to-head perfromance-wise with the likes of the BMW M5 and Mercedes-Benz E63 AMG.

As we told you here last Friday, the FIA, the governing body of Formula One, wants to use standard spec engines as of 2010 in an effort to reduce development costs and to even out the field in relation to engine technology.

On Tuesday the FIA met with the Formula One Teams Association to discuss methods for decreasing costs while still allowing teams to use their own engines. According to reports, some of the agreements made include extending the mandatory engine life from 2 races to 3, and making it mandatory for manufacturer teams to make their 25 engines available to independant teams at a cost of 10 million euros each.

On Tuesday we told you here that Chrysler had dropped it's V6 program codenamed "Phoenix".

Chrysler vice-chairman Jim Press says that the rumours are false. He says that Chrysler is moving "full steam ahead" on the program and prototypes are already at the testing phase.

Nissan has apparently made an offer to buy 20 percent of privately owned Chrysler.

The deal would keep Chrysler intact, one part of a larger company which includes Nissan from Japan and Renault from Europe. There is already a deal between Nissan and Chrysler that gets the Japanese maker a version of the Ram pickup truck and in return Chrysler gets a Nissan small car.

Chrysler is also in talks with GM regarding a possible merger ... but those two companies have many overlapping products and Chrysler would probably see itself dismantled.
