Jaguar has presented a sporting pack for the XFR called Speed. There is actually only two noticeable differences - a new front aero splitter and a new rear wing (3rd, 4th pics). But now Speed pack offers you the top speed of 280 kph (174 mph), still limited... :O
That makes me mad! OK to restricted top speed for the basic model (XFR), but if you offer the option especially for the speed (XFR Speed), then what is the sense to leave the top speed still limited, increasing it not much? That's silly and useless, when you can make it absolutely delimited to free all car's sporting potential!
