However, that doesn't leave a ton of separation between the current VQ V6 and the smaller turbo 6. My hope is that this is an indicator that they will be twin-turboing a VQ variant to the upper 300s in horsepower to keep the separation between engine specs. Just remember, until the 335i came around, a big selling point of the G was class-leading horsepower/quickness and it had a significant edge in that department.
They just have to do what they did with the VQ35 and VQ35HR and bump the G37 hp to 350.
