Proton’s Range Extender Electric Exora Prototype

Here’s something unexpected. We’ve not only got up close and personal with Proton’s prototype Exora EV, we’ve driven it already! And this wasn’t at a Proton event, but at the iGREET (Information on Green Technology) seminar series on green technology organised by Cyberview Sdn Bhd, the landowner of Cyberjaya. Proton was invited to this sixth and last iGREET session to talk about its foray into the electric vehicle scene.

As most know by now, Proton will roll out green cars in the near future that are often dubbed as “hybrid cars” by the media. In actual fact, the cars coming our way aren’t hybrids in the mould of the Prius or Civic Hybrid, but electric cars powered solely by batteries.

Proton’s Green Project Team is working with UK-based Fraser-Nash Research, Lotus, Imperial College London and Universiti Teknologi Malaysia (UTM) on a Range Extender Electric Vehicle or REEV – Proton is currently testing the REEV Exora with and without the range extender function, because it’s just a matter of switching the engine on or off.

Some of you might wonder what a range extender is? One of the main drawbacks of an EV is the limited range, and the RE engine takes care of this by providing the battery with juice when it runs dry. So you can reach your destination safely before plugging the car in. The Chevrolet Volt also uses such a system, where its ICE engine doesn’t power the wheels. The experimental RE in the Exora EV prototype is a 400 cc rotary engine with 50 hp. The mass production model most probably won’t come with a rotary, but the target is minimum 50 hp.

There are two electric motors powering this Exora – one for each front wheel. Each makes 35 kW to make 70 kW in total, while torque is rated at 220 Nm combined, available from rest. Proton has decided on the use of lithium polymer batteries, which is more advanced than the lithium ion variety, which is already better than the NiMH packs used in today’s hybrids. Targeted charging time from 10% to full is 6-8 hours while fast charging takes 30 minutes. Proton is aiming for 140 km/h top speed and 140 km range on the Saga body, so we’ll presume that the figures will be slightly less for the Exora.

A charging infrastructure is obviously needed, but at least EV drivers won’t be stranded due to the range extender engine. The REEV Exora is heading to production as early as next year, although nothing is confirmed at this point, which is why we don’t have a detailed technical analysis.

What we have however, is driving impressions of the REEV Exora. We drove the exact same car that won the “Best Range Extender EV” award at the Royal Automobile Club (RAC) Future Car Challenge in England earlier this month. Read it and view the pics after the jump!

Proton Saga facelift unveiled at Thai Motor Expo 2010

We’re here at the Thai Motor Expo 2010 for some pre-KLIMS motorshow action, where Proton has unveiled the 2011 Proton Saga facelift! Here’s an initial list of changes from what we’re able to tell so far:

The entire front end has pretty much changed from the head lamps, grille, bumper, and even the engine hood sheet metal design. The new engine hood now creases in a way that makes the left and right sides of the hood higher. There’s also a very faint spine in the middle of the hood, where in the pre-facelift Saga it was flat.

The headlamps now appear to use three bulbs instead of the previous two bulb config – we think this means there’s a dedicated bulb for high beam now. The signal lamps have been moved towards the inside of the lamps.

The wing mirrors now have turn signal indicators.

The rear end also has significant changes. The tail lamps are new and have LED lighting. There’s a small spoiler on the boot lid, and because of the spoiler design the Saga badge has to be relocated slightly to the left.

The bumper now has a black insert for the diffuser-like design feature, and it’s now wider with reflector lenses and shaped to show off the exhaust muffler and tail pipe, as opposed to the pre-FL Saga which had its rear end designed to hide the exhaust tail pipe.

The 1-DIN Clarion radio looks the same to us (except for the MP3/WMA logos which indicate support for those files), but there are new USB and AUX-in ports which are not integrated into the radio but are instead positioned to the lower right of the radio. This takes up some of the cubby hole space below the radio.

The steering wheel now has audio control buttons, similiar in style to the Satria Neo’s.

The fabric pattern on the door cards and the seats are now of a different design (old one is on the left). The baseline model in Thailand has a yet another different fabric pattern, and the one we are showing above in comparison to the old fabric is the high spec fabric pattern.

There are now rear power window button controls. As for which of the Malaysian car specs will feature rear power windows and which won’t, we’ll have to wait for the Malaysian launch.

There’s a new alloy wheel design, but the tyre size is the same as before – 185/60R14.

There’s now the option for a front passenger airbag which takes up the ’tissue box’ holder compartment in the pre-facelift Saga.

These are the only changes we are able to see so far, and we have to note that some of these updates like the USB/AUX function, the extra airbag and the rear power windows could only be for the higher spec models. Four colours are available in Thailand – Solid White, Tranquility Black, Genetic Silver and the new colour you see here which is Blue Rock.

There could be other changes on the mechanical side of things though, which we will probably only be able to find out when we speak to Proton’s engineers in Malaysia. The Thai spec sheet (which you will be able to see after the jump) quotes 70kW and 120Nm, which is the same as the pre-facelift Saga.
