2009 Infiniti M35 will get a 3.5-liter VQ35HR engine
Nissan reportedly plans to update its Infiniti M35 mid-size sedan with a more powerful version of the 3.5-liter VQ engine.
Called the VQ35HR and first featured in the second-generation Infiniti G35 almost two years ago, the new V6 has a maximum power output of 303hp and a peak torque of 355Nm (326lb-ft). It will power both the 2009 Infiniti M35 and the sporty all-wheel drive M35x.
Mated to a new seven-speed automatic gearbox, the VQ35HR will feature 10 percent better fuel economy, but will be about 10 percent more powerful than the outgoing powerplant.
The extra mileage comes courtesy of reduced weight and friction, and slightly smaller piston side-force thanks to asymmetrical piston skirts and longer connecting rods.
