Lotus launches new lightweight and modular EV architecture

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


We have known for some time that the emira will be Lotus’ last internal combustion model, but the company has been silent on what its next-generation cars will be from a technical standpoint. Now, thanks to an announcement on Tuesday, that picture is getting a bit clearer.

Lotus launches its lightweight electric vehicle architecture, which is not only lightweight but modular. This means that the folks at Hethel can use this architecture for a variety of models, including the Electric SUVs he spoke about it earlier this year. Lotus claims that a LEVA-built rear subframe is up to 37% lighter than the unit found in the future Emira V6, and this car is not what anyone would call portly.


The 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 configurations. The “slab” pack is intended for use in the two plus two models and can accommodate a pack of up to 66.4 kilowatt hours. Lotus also offers minifigures for two different two-seater versions, each using a “trunk” style pack that mounts behind the seats rather than on the floor. These can accommodate packs of 66.4 or 99.6 kilowatt hours.

The company doesn’t go into detail on the LEVA style of construction and how much lighter it is than other methods, beyond saying it will use spot welding, “cold processing” , which we assume means panel bonding adhesive and “advanced welding processes.” Lotus plans to use LEVA for its own vehicles and also in designs for Lotus Engineering customers. This means that we could see LEVA in more affordable and less sporty models in the years to come.
