Nearly 30 years ago, the Jeep® Grand Cherokee began its legacy as the most awarded SUV in history. Today, following four groundbreaking generations of the vehicle, countless industry accolades and nearly 7 million in global sales, the Jeep brand continues to shatter expectations of the full-size SUV segment with the all-new 2021 Jeep Grand Cherokee L. The newest iteration is designed and engineered to deliver an unmatched combination of even more legendary 4x4 capability, superior on-road refinement, premium styling and craftsmanship inside and out, and a host of advanced safety and technology features. The result is the all-new 2021 Jeep Grand Cherokee L, for the first time ever with seating for six or seven. The 2021 Jeep Grand Cherokee L delivers improved unrivaled capability along with composed on-road driving dynamics. Legendary off-road capability begins courtesy of three 4x4 systems – Quadra-Trac I, Quadra-Trac II and Quadra-Drive II with rear electronic limited slip-differential (eLSD). All three systems are equipped with an active transfer case to improve traction by moving torque to work with the wheel with the most grip.
When developing the new Mirai, Toyota optimized every aspect of the vehicle so that it appeals to customers emotionally - in terms of power delivery and performance as well as the way the car drives and looks. The declared goal was to increase the range compared to the first generation to a level that exceeds most purely battery-electric cars. To achieve this, the engine output and the capacity of the hydrogen tanks increased, as did aerodynamic efficiency. The result: a 30 percent larger radius of action that now reaches a good 650 kilometers. This means that the Mirai is now finally moving up into the long-haul vehicle class. Toyota has devoted itself equally intensively to the room layout. The modular GA-L platform, which serves as the basis for the new Mirai, enables considerably more effective packaging. In favor of a more balanced arrangement of the new FCEV drive train, the fuel cell unit has now moved under the hood. In this way, it clears the way for a larger interior space that can now accommodate five passengers.
