The now-discontinued Renault Twizy was known for its futuristic styling, scissor doors and unconventional seating layout, but never for outright performance. No one has ever accused it of being fast. That, naturally, made it the perfect candidate for something irresponsible.

Enter the UK-based mad scientists at DM Performance, who looked at this humble heavy quadricycle and decided it needed more chaos. Their solution was simple in theory and mildly unhinged in practice: rip out the weedy motor and transplant the heart of the world’s most powerful electric motocross bike.

The project started with a full teardown. Out went the factory-fit 17 hp (13 kW) motor. In came the powertrain from a Stark Varg, effectively the electric equivalent of a 450cc gasoline engine. The result is 80 hp (60 kW), a staggering 396 percent jump in output that completely rewrites the Twizy’s modest résumé.

But torque is the real headline here. The Stark Varg motor is rated at a frankly absurd 692 lb-ft (938 Nm). For context, the Lamborghini Aventador in the opening photo delivers 690 hp and 509 lb-ft (690 Nm), which means this pint-sized French creation is packing nearly double the torque of a V12 supercar!

It actually gets wilder. The supercharged 6.2-liter V8 in a 2027 Ram TRX produces 680 lb-ft (921 Nm). Now picture that sort of twist in a vehicle that weighs roughly ten times less than the Ram, and you begin to understand just how outrageous this thing really is.

Engineering The Swap

Making it all fit required serious surgery. DM Performance cut away the original rear cradle to accommodate the new motor and engineered a custom chain-drive system to replace the Twizy’s direct-drive transaxle.

To cope with the tidal wave of torque, they modified the original differential with a custom stainless steel casing and high-pressure grease to mimic the behavior of a limited-slip diff. A set of Maxpeedingrods coilovers was also installed to reduce the risk of an impromptu rollover.

Finally, the French EV received another transplant. The Stark Varg battery pack weighs 32 kg (70 lbs), significantly lighter than the Twizy’s 100 kg (220 lbs) battery, while offering slightly higher capacity and the ability to discharge massive amounts of energy for high-performance motors.

Smoke, Speed, And Proof

The unique “Stark Twizy” proved its performance credentials by winning a 100 mph (161 km/h) drag race against a more powerful Audi S1 Quattro hot hatch. The builders also took it for a drift session and even performed donuts around a Lamborghini Aventador.

A History Of Madness

This isn’t the first time DM Performance has turned a tiny EV from the heavy quadricycle segment into a monster. They previously completed a wild Citroen Ami using similar Stark Varg internals, though they noted the rear-wheel-drive layout of the Twizy made it a much better platform for hooning.

Electric swaps not your thing? They have also created a turbocharged Hayabusa-swapped Tuk Tuk tricycle. That machine weighs 460 kg (1,014 lbs) and produces a frankly terrifying 305 hp (227 kW / 309 PS) on the dyno.

Solid-state batteries promise to be the next big thing and they’re finally coming to road-going vehicles. One of the first companies to offer them is Verge Motorcycles, which said customers can expect a significantly faster recharging time as well as nearly twice the range of conventional batteries.

Set to become available in the coming months, the solid-state battery will be offered in the Verge TS Pro. The company didn’t go into many specifics, but the battery is sourced from Donut Lab and will be offered in 20.2 and 33.3 kWh configurations. The former provides 217 miles (349 km) of range, while the latter increases that figure to 370 miles (595 km).

When it comes time to recharge, a 200 kW NACS charger can deliver 186 miles (299 km) of range in as little as ten minutes. That’s pretty impressive and the company noted the “upgraded battery pack does not affect the motorcycle’s price.”

The good news doesn’t end there as Verge said the solid-state battery will “last for the entire lifetime of the motorcycle,” which is opposed to “thousands of charging cycles” for traditional batteries. The company also noted safety benefits as solid-state batteries “do not catch fire, making them much safer for users and charging locations.”

Solid-State Claim with Big Numbers

For their part, Donut Lab said they’ve created the “world’s first solid-state battery that is ready for use in OEM vehicle manufacturing.” The company went on to say the battery has an energy density of 400 Wh/kg and has been designed to last up to 100,000 cycles. That would seemingly equate to nearly 274 years of daily use.

The company also noted the battery has been “rigorously tested across extreme conditions.” At both -22° F (–30° C) and 212° F (100° C), it retained over 99% of its capacity.

Getting back to the motorcycle, the solid-state Verge TS Pro will start at $29,900 when it arrives in the first quarter. It will feature an electric motor developing 137 hp (102 kW / 139 PS) and 737 lb-ft (998 Nm) of torque. This will enable the bike to rocket from 0–60 mph (0-96 km/h) in just 3.5 seconds.
