Kalmar's electrification of the 964 generation 911

Danish tuning company,culmerhas announced a project to convert a 964-generation Porsche 911 into an electric vehicle (EV). Named the "7-97 E-Volt," this EV conversion is,They are using the Tesla Model S powertrain.
Kalmar did not just want to install Tesla's powertrain in the 911, but also to improve the car's environmental performance while also improving its performance. The result is the 7-97 E-Volt.

Thorough weight reduction and aerodynamic improvement

The project started as a donor car, a 964 generation 911 that was missing its engine. Kalmar restored this car using as many genuine parts as possible. Even more surprising is the thoroughness with which the car's aluminum was melted down and recast. The same process was applied to the glass.
Perhaps most impressive is the use of flax-based composite materials to fabricate a new lightweight body.This material is also used in the interior to further reduce weight. According to Kalmar, the 7-97 E-Volt weighs approximately 1,374 kg, equivalent to a 964-generation turbo model.

Improved aerodynamic performance

He says the new body and glue-in glass, which reduces drag by eliminating gaps, have improved aerodynamic efficiency while maintaining downforce. According to Kalmar, compared to the donor 911, 301 TP3T downforce is increased in the front and 201 TP3T in the rear. In addition, the optional ducktail spoiler increases the rear downforce by an additional 601 TP3T.

Tesla-derived powertrain

The star of the EV conversion is still the powertrain. A single electric motor mounted on the rear axle delivers up to 450 hp and gets its energy from a 63 kWh battery that is split between the front and rear to optimize weight distribution.
In terms of performance, the 0-100 km/h acceleration is said to be less than 4 seconds, and the cruising range is said to be up to approximately 290 km (180 miles). They can choose between eco mode and sport mode with the drive mode selector.

Modern features include electric power steering, air conditioning, LED headlights, rain-sensing wipers, and an Apple CarPlay compatible infotainment system. They have also added an electric vacuum pump to operate the power steering, air conditioning, and brake booster system. The brakes have a choice of steel rotors or lighter-weight carbon ceramic ones.

7-97 E-Volt conversion prices areFrom 450,000 euros (approx. 70 million yen)It is believed that According to Kalmar,Future owners can revert to internal combustion engine if they wish.I am glad to see that the modification is reversible.

This project represents a challenging attempt to integrate modern technology without compromising the appeal of classic cars. Kalmar's ambitious approach to combining environmental friendliness with performance suggests new possibilities in the classic car world. For Porsche enthusiasts, this is a project worth watching to see how such an initiative will affect the future of classic Porsches.
