Since the Cadillac CTS-V wagon came out, it's hard to imagine a brake that we would like better. The Jaguar XF Sportbrake aims to be edgy, but compared to the CTS, its rounded body looks pretty weak. As for under the hood, you can chose between either a four-cylinder or six-cylinder diesel. The six gets to 60 in 6.1 seconds behind 270hp. It doesn't really matter anyways. This thing won't make it to the States any time soon.
