Electomobility The Lightweight Design of Jaguar`s I-Pace
With the launch of the I-Pace, Jaguar tries to take the lead in the E-Mobility revolution. Thus, it tries to keep up with the industry’s leader Tesla. Lightweight construction plays a major role in the manufacturer’s new SUV.
The I-Pace is Jaguars attempt to align performance, technology and interior space as much as possible in order to ensure competitive advantages. The car offers space for a total of five adults and 656 liters of luggage. Furthermore, state-of-the-art technologies have been included. Wireless over-the-air updates ensure that the latest software is installed at any time. By using artificial intelligence algorithms, the car adapts itself to individual driver preferences. The vehicle is expected to be available for purchase as of summer 2018.
In line with the Jaguar look, the I-Pace incorporates both a distinctive grille and the “Double-J” light signature. The lightweight construction has a great influence on the streamlined design. The I-Pace has a drag coefficient of 0,29. It consists of a lightweight aluminum body, so its weight is only 2,208 kg. The body consists of 93 % aluminum, mostly various alloys, in particular grades 5,000 and 6,000, as well as RC 5754 special aluminum, which is obtained in Jaguar’s closed-loop recycling process. Added to this are 4 % boron steel and 3 % steel. The bonnet and doors are also made of aluminum. Further weight savings were possible by using composite materials for the front mudguards and the tailgate (polypropylene and SMC). The aluminum battery frame is an essential part of the body structure: the frame protects the battery and carries it at the same time. The battery frame has been integrated into the development of the body.
The I-Pace can reach 298-miles with a single charge which is measured by Worldwide Harmonised Light Vehicle Test Procedure WLTP. The charging of Jaguars SUV takes 40 minutes from 0-80 %. Charging the car for another 15 minutes ensures up to 62 miles extra range. For this purpose, a 90 kWh Lithium-ion battery integrated into the vehicle. Tesla’s X 75 D has a range of only 259 miles. However, this distance is measured according to NEDC (New European Driving Cycle), which is not the latest method of doing this.

Some experts suspect that the I-Pace could be a real game changer. Jaguar has put some effort in producing another premium EV. The combination of dual electric motors which are integrated in the axes and high-performance batteries offer a range challenging Tesla. It will be exciting to observe the further development of the two projects and how they separate the market share among each other.
