Before the Jaguar E-Pace makes its debut, the British carmaker is providing an insight into the development process of its latest SUV model that will be positioned below the F-Pace and upcoming I-Pace.

According to Jaguar, the E-Pace endured a gruelling 25-month test programme, which required more than 150 prototypes to be built. Testing took place across four continents to ensure the E-Pace was not only durable, but capable of coping with the harshest of weathers. Jaguar says that the E-Pace has been through in excess of 120,000 hours of testing in total involving more than 500 engineers.

From the deserts of the Middle East to the Arctic Circle, the E-Pace prototypes encountered temperatures from a freezing -40 degrees Celsius to a scorching 48 degrees Celsius. The SUV even navigated the high altitudes (5,000 feet above sea level) and rivers of China’s most remote provinces.

Come hell or high water, Jaguar was determined to make sure the E-Pace would perform on- or off-road. The former involves lapping the Green Hell (the Nordschleife circuit at the Nürburgring) more than 400 times to deliver a performance SUV worthy of the Jaguar badge.

As for the ‘high water’ bit, the E-Pace was driven to the centre of a 0.5 m deep pool of water in Jaguar Land Rover’s wading test at Gaydon. The engine was switched off, all the doors were opened and left for an hour, before the car was started back up and driven out.
