Lotus Theory 1 Concept Hints at All-Electric Esprit Successor

The radical Lotus Theory 1 Concept pays homage to the original S1 Esprit.

It is no secret that Lotus is planning to make a new sportscar to go along with its new all-electric lineup. While the previous rumour said that the model will be launched in 2027, it seems we’ve gotten an early preview of this upcoming sportscar as the Anglo-Chinese marque unveils its latest concept model—the Lotus Theory 1.

Conceived as the all-electric successor to the original S1 Esprit, the Theory 1 is a pretty radical concept sportscar that features some design cues derived from both the aforementioned model and the current crop of Lotus EVs. For starters, the Theory 1’s wedge-shaped silhouette is taken directly from the original Esprit, while its aggressive front face featuring dual-stack LED headlights reminds us of the Emeya hyper-GT.

Unlike both aforementioned models, the Theory 1 takes up a notch with its aero parts, as the car features a radical front splitter and rear diffuser, plus some visible carbon fibre parts inside out. Thanks to the elaborate use of carbon fibre, the Theory 1 only weighs 1,600 KG, which is quite impressive for an all-electric sportscar.

The radical design continues as we get inside the Theory 1, where the concept comes with butterfly-style doors and a unique three-seat layout reminiscent of the legendary McLaren F1. Calling them seats might not do justice to Theory 1, as they consist of several cushion pads and headrests that are mounted directly to the car’s carbon fibre chassis, a la Lamborghini Sesto Elemento.

Beyond its skeleton design, these seats are part of Theory 1’s Lotuswear system of adaptive textile-covered robotics developed with Motorskins that can provide haptic feedback to the driver together with the steering wheel. On the topic of steering, the Theory 1 also comes with a steer-by-wire steering system instead of a conventional electric power steering system used on many cars nowadays, providing drivers the ability to adjust the steering ratio and feel on the fly.

Besides the unique steering system, there’s more impressive technology and innovation beneath the Theory 1’s carbon-cladded body, as the concept features an innovative chassis setup where both the battery and motor assemblies are used as part of the stress member for the suspension setup. This technology is no stranger to the Lotus brand, as it was previously used on some of its Formula One (F1) models.

Battery and motor setups, on the other hand, are quite typical of Lotus hyper-EVs, with the Theory 1 being powered by a dual-motor AWD setup rated at 986 HP that allows a rapid 0-100 KM/H sprint time of 2.5 seconds and a 320 KM/H V-Max. Meanwhile, the 70-kWh battery is good enough to provide the Theory 1 with up to 402 KM of EV range.

Elsewhere on the performance front, the Theory 1 follows the footsteps of its all-electric siblings by using the bespoke Pirelli P Zero Elect EV-specific performance tyres that are specifically designed to reduce rolling resistance and boost range by up to 10%. Combined with its relative light mass, the Theory 1 promises to deliver the same lightweight driving experience that the Lotus brand was known for in the last few decades.

Given how radical this concept is, it is quite surprising that Lotus has hinted that a production version of Theory 1 is currently in their pipeline. Speaking to Autocar UK, Lotus chief creative officer Ben Payne said around 85% of Theory 1’s technical features are "production-ready,"  thus suggesting that a production version might arrive sooner than we thought.
