Peak efficiency: All-electric Jaguar I-PACE completes 'Everesting Challenge' by climbing 8,848m – the height of Mount Everest – on a single charge
The award-winning all-electric performance SUV model was driven by Olympic and World champion cyclist, Elinor Barker MBE.
The concept of Everesting is simple, yet extreme: complete a series of runs up an incline until achieving an elevation gain of 8,848m – equal to an ascent of Mount Everest – and the popularity of this endurance challenge boomed among cyclists during the pandemic*.
Known by cyclists as ‘Britain’s Mont Ventoux’ – a reference to the daunting Alpine mountain stage in the Tour de France – Great Dun Fell is home to the highest surfaced road in the UK. The narrow ribbon of asphalt is defined by a series of sweeping bends and gradients of up to 20 percent as it climbs 547m from the start point used for the challenge to a peak of 848m. Elinor completed 16.2 repeats of the 5.8km climb (a 11.6km loop in total) using the I-PACE’s regenerative braking technology to generate approximately 60 percent*** of additional available energy over the total 16 descents.
Having covered 99.6km in total, including a 12.9km drive to the start point on the fell, the I-PACE completed its energy intensive challenge with 31 percent battery charge remaining – enough to drive for up to 128.7km more.
Key to the efficient completion of the Everesting challenge was the I-PACE’s regenerative braking system. Developed using technology from Jaguar Racing’s Formula E programme, ‘regen’ is a critical enabler for success on the track. In an average race the I-TYPE 5 generates around 30 percent*** of additional energy from regen, without it the car simply wouldn’t make it to the chequered flag.
Elinor Barker, MBE, said: “I watched with fascination as cyclists took up the Everesting challenge during lock down – even as a professional rider, it’s a daunting feat of endurance, so I was happy to do it behind the wheel of the all-electric Jaguar I-PACE. When I found out that Jaguar Racing drivers typically need to regenerate 30 percent of their I-TYPE's battery capacity in a Formula E race, as a competitor I naturally wanted to beat that figure! I’m delighted to have smashed that target – all while enjoying the comfort, silent power delivery and single-pedal driving of the I-PACE.”
Elinor was supported throughout the drive by members of the Jaguar Racing and I-PACE engineering teams, on hand to monitor the vehicle’s performance.
Jack Lambert, Jaguar Racing Engineer, said: “The advanced regenerative braking system developed for the I-PACE is a defining feature of the driving experience. Lessons learned through our Formula E programme on the track ensure I-PACE customers enjoy benefits on the road in terms of optimised range. The regenerative braking also provides up to 0.4g of deceleration so Elinor would only have been using the conventional friction brakes at two or three points on each run.”
In preparation for the challenge, the I-PACE was preconditioned using the Jaguar Remote App. While the vehicle is plugged in, preconditioning automatically heats or cools the battery to reach its ideal operating temperature and establishes the desired cabin temperature –using mains power. Using the grid to do this instead of drawing current from the vehicle battery optimises the driving range – especially in cold weather.
Another feature which enhances the I-PACE’s efficiency is Smart Climate, which uses the seatbelt sensors to determine how many occupants are travelling inside, and only heating or cooling the relevant areas of the cabin, maintaining comfort while minimising energy use.
The Jaguar I-PACE delivers outstanding performance with acceleration from 0-100km/h in 4.8 seconds and up to 470km range (WLTP).** In 20 minutes, 60kW DC and 100kW DC chargers can add up to 100km and 127km of range (WLTP) respectively. ****

The first ascent of Everest was completed on 29 May 1953 by Sir Edmund Percival Hillary and Tenzing Norgay.
The I-PACE has been designed and engineered in the UK and the country will remain the heartland of Jaguar Land Rover’s manufacturing, engineering and design operations. Jaguar Land Rover builds the I-PACE in Austria as part of a manufacturing partnership with Magna Steyr.
Reaching new heights: Performance SUV completed 16.2 ascents of Britain’s highest surfaced road – Great Dun Fell – gaining 547m on each full climb
Race-to-road technology: I-PACE’s clever regenerative braking – developed with learnings from the Jaguar Racing Fomula E team – recovered equivalent to 93.3km of range under the challenge’s extreme conditions
