I bought this 2007 400h for my wife. I did a fair amount of research before making the purchase. I saw the hp rating of 268 and felt that was ample. What I thought was weird is that I could never find any real peak combined torque figures. When we test drove it I just kind of putted around and didn't really hit the pedal much. On the way home after I bought it, I gave the go pedal a nice stab to merge into traffic from an exit. I was not prepared for what happened next. The thing lunges forward with a healthy dose of torque steer I might add, and the traction control light was blinking it's !Removed! off. I was shocked, but grinning ear to ear. I've built high powered turbo 4 bangers (used to have a 650whp Eagle Talon AWD) so I'm used to big HP, but a turbo kind of sneeks up on you and hits you gradually until full boost, then WHAM! This 400h however, has gobs of torque from the jump. Very satifying and surprising! Especially for a V6.
The tinkerer in me wants to find out how to unleash the full potential of this powertrain, but I'm sure the wife wouldn't be too happy with me fiddling with her new baby!
