Concept crossover joins Porsche’s Mission E line
As a follow up to the all-electric Mission E concept car from the 2015 Frankfurt Motor Show, Porsche showed at the 2018 Geneva Motor Show showed a crossover adaptation called the Mission E Cross Turismo. Labeled by the company as a CUV (Cross Utility Vehicle), the new four-door four-seat crossover concept is 4.95 m (194.9 in) long, 1.99 m (78.3 in) wide, and 1.42 m (55.9 in) tall and features all-wheel drive and an 800-V electrical architecture. The Cross Turismo is said to be “fit for the road” and could join the Mission E car due next year.
Distinctive design elements are intended to link the Cross Turismo to the concept and production Mission E car and to Porsche’s iconic 911. They include front vertical inlets known as air curtains and matrix LED headlights that continue the brand’s four-point daytime running/indicator lights along with high-performance full beams using Porsche X-Sight technology. In the rear, both the “E” in a Porsche logo composed of glass letters and the circuit board design cover pulse light when charging. A large panoramic glass roof extends from windshield to hatchback top for an interior that is lighter and has a more generous sense of space. Off-road design elements include protective wheel-arch and door-sill extensions, increased ground clearance, and 275/40R-20 tires.
Porsche promises that the Mission E level of continuous power will be unmatched by any other electric vehicle, with multiple accelerations possible in direct succession without loss of performance—this boast being aimed primarily at Tesla. Two permanent magnet synchronous motors with total system output of more than 600 hp (440 kW) allow the crossover to accelerate from 0 to 100 km/h (0 to 62 km/h) in less than 3.5 s and to reach 200 km/h (124 mph) from rest in under 12 s. On-demand all-wheel drive with torque vectoring automatically distributes output to individual wheels. Other running gear highlights include all-wheel steering for agility and stability, adaptive air suspension that can increase ground clearance by up to 50 mm (2 in), dynamic chassis control for active roll stabilization.
“Our vehicle will be fast to drive, but also quick to recharge and able to replicate its performance time after time,” said Oliver Blume, CEO of Porsche AG. Engineers at Porsche have prepared the concept for a future fast-charging network being created by the Ionity joint venture, founded by BMW, Daimler, Ford, and Porsche parent Volkswagen Group, aimed at construction of the most powerful fast-charging network for e-vehicles in Europe. Ionity plans to set up and operate around 400 fast-charging stations by 2022.
According to Michael Kiefer, Head of High-Voltage Systems at Porsche Engineering, new electric powertrains will only gain widespread acceptance once these facilities are in place. “To provide the customer with a seamless experience, the infrastructure must be in sync with what the vehicle can do,” he added.
So Porsche has developed a special charging station for its high-performance vehicles. The quick-charging technology features a voltage of 950 V and charging performance of up to 350 kW, allowing drivers to “fill up” in less than 20 min. The 800-V architecture of the Mission E vehicles enables the lithium-ion battery pack to be charged for a range of about 250 mi (400 km), according to the NEDC (New European Driving Cycle), in just over 15 min. However, the crossover can also be charged by induction, at more conventional public charging stations, or using a Porsche home energy storage system.
Interior flexibility is aided by individual rear seats with load-through facility for skis and other long items, backrests that can be folded down, and a rail system with adjustable and removable straps to secure cargo. The dashboard is composed of wing-shaped upper and lower portions with an extra-wide display between them for driver and front passenger use.
Porsche is especially proud of the interior user experience, with intuitive operation, information optimally positioned in the field of vision with a non-distracting headup display, and new connectivity solutions to support an integrated digital lifestyle.
The instrument cluster includes three circular displays digitally rendered with TFT screens. The three virtual instruments are divided into areas for Porsche Connect, performance, drive, energy, and Sport Chrono. A camera in the rear-view mirror tracks the eyes of the driver, with the instruments the driver is looking at brought to the foreground. Passenger can operate various apps to control features such as media, navigation, and air conditioning also using eye-tracking. Smart touch controls are used on the steering wheel. Touch screens are featured on the center console and for multifunctional window lift and seat adjustment as well as in the slatted air vents on the right and left of the dashboard.
Interior customization options—from air conditioning to navigation—can be planned ahead using a tablet, smartphone, or smartwatch. As part of Porsche Connect, DestinationsApp shows what is possible in the near future, inspiring users with travel destinations, facilitating quick and easy bookings, and taking care of route planning, food, and sports equipment.
