This is the brand new Mercedes-AMG E63 Estate which is the world's fastest wagon ever. It has a 4 litre twin turbo V8 that produces 604bhp. The regular car makes 563bhp and 553lb ft of torque whereas the S version ups by 41bhp and 73lb ft of torque. The "S" is quicker by 0.1 sec(3.5 - 3.6)in a 0-60 race. The S version gets a drift mode unlike the normal car. We'll see it in March's Geneva Motor Show ahead of sales in April letting Audi add more horse power to the Estates's rival, the RS6 Avant.
