Lightweight Electric Sports Car

Speedster

A sub-800 kg electric sports car engineered to deliver pure, analogue driving engagement in a world dominated by heavy, software-overloaded EVs.

Less weight.
More connection.

Modern electric cars have become appliances — heavy, numb, disconnected. The Speedster exists because electrification should amplify the driving experience, not bury it under two tonnes of battery and sound deadening.

At sub-800 kg, every watt goes to moving you, not mass. Every steering input arrives unfiltered. This is what an electric car should feel like.

01
Lightweight
Sub-800 kg target. A fraction of any production EV. Every component justified, every gram earned.
02
Electric
Instant torque to a car light enough to use it all. No gears, no lag. Two powertrain tiers — 108 kW for the road, 214 kW for the track.
03
Honest
Up to 200 km real-world range estimate. Not a fantasy WLTP number — a realistic target based on the roads this car was built for.
04
Analogue
Physical controls, rotary encoders, motorsport-inspired digital instrumentation. No touchscreen dependence. A human-centred car, not another autonomous appliance.

Two trims. One philosophy.

Same platform. Same chassis. Same differential. The powertrain defines the character.

Road
Speedster E
The lightweight road car in its purest form. 108 kW and 193 Nm through less than 750 kg — linear torque delivery, high mid-load efficiency, and a chassis built to make every B-road an event. Accessible, engaging, unfiltered.

03 — Design

Born from emotion,
shaped by purpose.

Every surface serves a function. Every line carries intent. The Speedster's form isn't styled — it's resolved. Open wheels, exposed mechanicals, and a silhouette low enough to feel part of the road.

"Emozione — the driving force behind the Speedster's design. The thrill of driving it, of looking at it, of owning it. A creature with a strong persona, waiting to share all its energy with you."
Luca Biselli — Lead Designer

Proven components.
Purpose-built integration.

The Speedster integrates motorsport-grade components into a platform engineered from the ground up for one thing: driving. Same chassis, same differential, same philosophy — two fundamentally different performance levels.

Powertrain
Two powertrain tiers on a shared RWD platform. The E trim pairs an Engiro motor with a Turntide inverter for linear, efficient road performance — 108 kW, 193 Nm. The S trim steps up to a Brusa HSM1 motor and DMC544 inverter — 214 kW, 302 Nm, with thermal headroom for sustained track use. Both drive through a mechanical limited-slip differential with 4.88:1 final drive.
Battery System
Two battery strategies, same philosophy: keep it light, keep it usable. The E trim runs a 22.5 kWh NMC pack with a Wattius MX Pro BMS and 52 kW DC fast charging. The S trim uses a 22 kWh STARD pack rated to 450 V with dedicated RESS cooling for motorsport-grade thermal stability. Both prioritise power density over range marketing.
Chassis & Body
Motorsport-derived tubular frame developed from the ground up — not adapted from a donor vehicle. Body panels combine CFRP for structural stiffness, GFRP for impact-tolerant exterior surfaces, and 3D-printed components for complex geometries without tooling cost. UK IVA homologation path.
Drivetrain
6082 billet aluminium casings with a 180 mm crown wheel and pinion, combined with the smooth operation of a limited-slip differential. 3×2 spiral gear technology delivers progressive, variable traction — based on throttle input, you control how much traction is applied. Finesse where it matters, grip when you need it.
