Proton Preve REEV Revealed

Late September, Proton unveiled at its headquarters in Shah Alam, Malaysia the Preve REEV prototype. (

This is a range-extended electric car based on the conventional Preve model.

It has 15.7 kWh worth of lithium-ion pouch cells (stated energy density at the cell level is 163 Wh/kg), which should be enough to drive over 50 km (31 miles) in all-electric mode.

An 80 kW outer-rotor PMSM type motor with 170 Nm of peak torque enables it to go up to 128 km/h (80 mph) and accelerate from 0-100 km/h (62 mph) in a not so thrifty 14.7 seconds.

There is also a small 1.3-liter engine, which serves as backup.

On the ECE R101 test cycle, fuel economy stands at just 0.82 l/100 km (but only for the first 100 km when the battery pack is charged). Then the 1,724 kg (3,800 lbs) car must consume much more fuel.

“According to the Proton engineers manning the booth, the more powerful generator engine allows the Preve REEV to maintain highways speeds even when the batteries have been exhausted, as the more powerful engine can now produce enough power in real time to keep the car going at high speeds.”

“It’s a prototype to test the REEV system, so the engine bay packaging hasn’t really been done to production car standards. As a result, the engine is mounted high, and the engine hood had to be modified with a bump to clear the engine. The 15.7 kWh lithium ion batteries are mounted under the floor, and the fuel tank has been moved a little to the rear to make way for this.”

Here are some additional details:

‘It has 15.7 kWh of lithium-ion pouch cells (stated energy density at the cell level is 163 Wh/kg)’

A bit disappointing at this stage of the game.
The venerable technology in the Volt is around 140Wh/kg at the cell level.

It is proving incredibly difficult to up battery energy density, or more accurately specific energy if we are being picky.

Still, it is good to see a second tier company like Proton get in the game.


“second tier company like Proton….”



They are a good company, and know that they have a lot to learn still, as they are relative newcomers and getting car production right and consistent quality is tough.

And Tesla’s is up around 250Wh/kg at the cell level. Using lightly-modified commodity cells that (by definition) anyone can use.

50 km all electric seems very low. And 0,82 l/100km for the first 100 km must mean it can drive 80-90 km on electricity.

Anyone know more exactly how the ECE R101 works?

Is there any other source of information for this model?

It’s like a second source for that 50km range on electricity. That must be in -20, up hill and with the wind against you 😛


That will be 50km on the NEDC cycle, around 22 miles on the EPA, the same as every company that is not American is aiming for, as it is what China has specified as ZEV eligible for city driving.


That’s a VERY attractive sedan. Why can’t other OEMs make more EVs and PHEVs look like this?


I hope they make the Preve REEV a PHEV or an all Electric car…..Go Proton.
