Jaguar’s XE will compete with the likes of BMW’s 3 Series, Audi’s A4, Mercedes-Benz C-Class.The spiritual successor of the X-Type will receive a generous engine family that will include a “high-output unit” enabling the model to reach a maximum speed of 300km/h. The automaker is planning a frugal variant that could produce “less than 100g/km”. Jaguar’s XE is expected to be launched in 2015.
