Guys that straight line acceleration. You don't buy a Boxster or an Accord for that matter for straight line acceleration. If you want to do 1/4 mile times, buy a Supra, Talon or Rx7. Those are straight line cars, though they can all do corners well if you want. If your into newer cars that you don't modify, buy a Corvette Viper or Mustang GT they are all fast in a straight line and can't corner to save their lives. The new Corvette still uses leaf springs if you can imagine that. LEAF SPRINGS!!!!
The Boxster is a track and cornering car. If you put the new Accord against the Boxster at a track, it could not keep up. Even with 400hp a front engine FWD car just can not keep up period. The Accord would be left sliding off the road looking like a poor excuse for a car. Front wheel drive is the work of Satan and no real car is FWD.
The Accord is not as fast as a boxster in any way shape or form. It will not break as fast, it will not turn in as fast, it will not go as fast around a track, corner or anywhere else where real driving counts. It will however go in a straight line as fast, whoptie do. If thats what your looking for, buy a train cause they do that pretty well too. Hell with 409hp and 415ft/lbs I will bet the new Escalade will do 14.5 in the 1/4. Is it fast? Hahhah yeah, right.
