Lotus’s new EV-specific architecture will work with multiple wheelbases, seat configurations and power levels.

We have known that for a long time the Emira will be the final internal combustion engine from Lotus, but the company has remained silent about how its next-generation cars will be from a technical standpoint. Thanks to an announcement on Tuesday, this picture is now a little clearer.

Lotus introduces its Lightweight Electric Vehicle Architecture, which is not only light but also modular. This means that the folks at Hethel can use this one architecture for a variety of models, including the Electric SUVs it spoke earlier this year. Lotus claims that a LEVA construction rear subframe is up to 37% lighter than the unit featured in the upcoming Emira V6, and this car is not what anyone would call sedate.

Batteries can live under the floor or behind the seats.

Lotus provided figures for three different configurations of LEVA-based vehicles with two different battery pack layouts. The “slab” package is intended for use in two-plus-two models and can accommodate a package of up to 66.4 kilowatt hours. Lotus also has figures for two different two-seater versions, each using a “chest” style package that mounts behind the seats rather than on the floor. These can hold either 66.4 or 99.6 kilowatt hour packs.

The company does not go into detail about the LEVA style of construction and how it is so much easier than other methods, other than using spot welding, “work hardening” which we believe means panel adhesive, and “advanced welding”. “Lotus plans to use LEVA in its own vehicles and also in designs for Lotus Engineering customers. That means we could see LEVA in cheaper and less sporty models in the years to come.
