Lotus unveils Project LEVA electric architecture – DRIVE

The simplest version of the platform is shown here: a wheelbase of 2470 mm, two seats, a junior traction battery behind the cabin, one electric motor on the rear axle.

Recently unveiled sports car Lotus Emira – the last Lotus with internal combustion engine. Further, the brand is only waiting for electric cars… Limited Lotus Evija just opened a new era of Lotus, and other “electric trains” use the architecture developed in the framework of Project LEVA (Lightweight Electric Vehicle Architecture). Lotus presented its first results today at the Millbrook Proving Ground in Bedfordshire.

Version with a senior modular battery, a base of 2650 mm and a drive module with a double electric motor.

Modification with underfloor battery. With the same base of 2650 mm as in the previous version, the cabin is already with a 2 + 2 landing pattern.

The LEVA project was led by Vehicle Concept Chief Richard Rackham, who developed an ultra-light aluminum architecture from the extruded profiles of the original roadster. Lotus elise 1996 year. According to Rackham, LEVA is as revolutionary as the Elise 25 years ago. Here, significant weight savings have been achieved through a number of measures. So, part of the supporting structure is the battery housing, the multi-link suspension is weight-optimized, the integrated EDU drive module is mounted without a separate bolted subframe. In addition, the architecture is flexible, allowing you to vary the length of the base, the number of locations (2 or 2 + 2), the size and even the layout of the battery, the drive modules.

The rear power structure of the LEVA is 37% lighter than that of the Emira, the developers assure. By the way, the company Sarginsons Industries and scientists from London Brunel University helped Lotus.

Lotus Type 132 is not associated with the LEVA project. But if not for architecture, then for battery modules and motors, intersections are not excluded.

Batteries in LEVA architecture can be in the form of a “chest” (Chest) or “plate” (Slab). The first is located behind the cabin, the second is under the bottom, like modern skateboard platforms. The minimum wheelbase in the project is 2470 mm, in other models it can be 2650 and more. A Chest battery with a short base and a Slab battery with a long base will store 66.4 kWh of energy in eight modules. The more capacious version is the Chest with a long base: 12 modules of 99.6 kWh. The EDU module can develop 350 kW (476 hp) with a single motor and 650 kW (884 hp) with a dual one.

The Type 133 will arrive in 2023 as a coupe version of the Type 132 crossover.

The LEVA architecture should spawn several platform versions for future Lotus, in particular E-Sports, which is being developed with Alpine for the model of this brand and the sports Lotus 2026 (Type 135). But in the Lotus program will appear and crossovers… The company has planned the Type 132 SUV for 2022 to battle rivals such as Tesla Model X, BMW iX and Mercedes EQE SUV… It, like the subsequent models Type 133 and Type 134, should be assembled in Wuhan using some kind of Premium Architecture, probably bound with Geely SEA… Older versions are expected to have batteries up to 120 kW • h and motors with a total power of up to 550 kW (748 hp).
