Lotus Reveals Tech For Next Generation of Electric Sports Cars

Lotus has unveiled the innovative new lightweight chassis technology that will underpin its upcoming electric sports cars.

The new structure has been developed through Project LEVA (Lightweight Electric Vehicle Architecture) – a research program that’s accelerating the development of all-new lightweight structures for next-generation battery electric vehicles.

The versatile nature of the architecture means it is fully adaptable and can provide a platform for a range of EVs with variable layouts, wheelbase lengths, battery sizes and configurations.

The three revealed layouts feature a common lightweight die-cast rear sub-frame with multiple interchangeable components. It means a single vehicle architecture can accommodate two different types of battery configurations:

  • ‘Chest’ layout, where the modules are stacked vertically behind the two seats. A chest layout is a ‘mid-mounted power pack’, ideal for sports car / hypercar vehicle types where a low overall ride height and low centre of gravity are required.
  • ‘Slab’ layout, where the modules are integrated horizontally under the cabin. This, Lotus says, is most suitable for vehicles where a higher ride height and a taller overall profile is required. It is often referred to as a ‘skateboard power pack’ layout.

The new subframe features cylindrical battery cells for high energy density, with the option of a single or twin electronic drive unit (EDU). Cold cure, spot bonding and advanced weld processes mean reduced environmental impact during assembly.
