Audi RS4 - hands down the best station wagon ever made!
For those that don't know it's an 6 cylinder DOHC twin turbo intercooled monster (sound familiar?)
power wise it's 280kW@6100rpm and 440Nm@2500rpm
0-100 in 4.9.
not bad for a "family" car
edit: forgot it's 6speed manual and AWD
there's an RS6 which is basically the same, just not a station wagon.
