Conventional superchargers are powered by a belt connected to the car’s engine. As more power is dialed up, the supercharger draws more and more power away from the engine and in turn burns more fuel.
Earlier this year British firm Controlled Power Technologies (CPT) revealed an electric supercharging system developed for small fuel-efficient engines that does away with the belt system. Dubbed the Variable Torque Enhancement System (VTES), the new system is ready for mass production and can be applied to all types of petrol and diesel engines including those already turbocharged.
Tests undertaken by CPT show that when the new electric supercharger is applied to a radically downsized and down-speeded engine, it significantly increases the initial response, delivering more torque at low engine speeds.
Initial testing has shown that a 1.2L engine with an electric supercharger can provide the performance of a 2.0L motor, with typically a 40% improvement in acceleration times over a non-forced induction motor of the same size. For diesel engines, a near instant air supply enables delivery of high torque with minimal particulate emissions, helping to keep CO2 emissions low.
CPT has now signed a deal with Switched Reluctance Drives Limited to start developing OEM units that will eventually appear in production cars. No release date has been given but given the desperation in the auto industry for cleaner and more fuel efficient cars the wait shouldn't be long.

I bet VW wish they had these a few years back for the development of their twincharger system!

this.... makes me hot. I wonder how much electric power it takes to get another couple pounds of boost. this really could be huge.
Ps., that acronym is crap. superchargers are forced induction off a belt. Turbochargers are forced induction off exhaust pressure. This should be called (something electrically)charger,.... uhm.... PowerCharger? ElectroCharger? AwesomeCharger? i dunno. anything but VTES (i had to scroll back up to the article just to remember the name its THAT stupid)

oh, i know this is completely unrelated but HECTOR.... if you dont mind,.. i wanna keep talking about these combo lights.... and i dont wanna have to flip back to the A6 article.... i saw your reply and I'm telling you, i still dont get it.
ok, so you're not talking about unique lights under a single lens, you're talking lights that are actually used for multiple purposes. yeah you're going to have to give me examples. cause i've got a 2nd gen focus, and i had a 1st gen focus... and i haven't the slightest clue what you're talking about. I live in Canada, and before you go spouting about how thats the reason, realize that any car sold in USA is the same as the model that is sold in Canada. with exception to the fact that the warning labels (for the airbag and crap like that) are in french as well.
Like i said, I've never noticed this issue that you're talking about where your brake light will flash instead of a separate turn signal. if you can think of one specific model.. that would be appreciated. I know we have mandatory running lights here but that doesn't change anything. just means your front lights are always on.

I can just see the ricers shouting VTES YO!!!

well... since you brought it up; what are the chances of getting a message board instead of these article threads? cause after a day or two,.. the thread dies. If we had a message board system where you could see on one page, who has posted something new on each thread, then we could get a little more resolution to the debates that we get started here.
besides, I really want to know what the heck hes talking about. cause the closest thing I've seen to what he's talking about is the new chryslers, where the front head light (only one) will shut off when the turn signal is on, to bring more attention to it. kinda good idea, but also very stupid cause i've seen a lot of new chryslers with burned out head lamps. they aren't made to turn on and off like that. If what he's saying is true, then it is really stupid. i just dont know what cars have it, and I've been looking. never seen it. Its really starting to annoy me. HECTOR!!!!!

Parry; at least VTES would mean something. I swear if I hear another punk kid talk about VTEC, you'll hear reports from canada about a kid who went through the outer brick wall of a Tim Hortons.
For those of you who aren't Canadian (just about all of you), Tim Horton's is a Canadian coffee shop with something like 3,000 locations. Many of them stay open 24hr, so you get a lot of ricer conventions on Friday nights in Timmy Ho's parking lots all over Canada. Mostly just body kits and K&N filters, but you get some Speed3's and STi's....... but mostly just a bunch of pubescent testosterone.

Forums are coming soon as well as a complete site redevelopment. :)

site redevelopment? i rather like the look of this site. Its nice and clean. update it all you want but don't clutter it up.. you go to other pages and theres banner ads all over the place, and... well they're all just a mess.
when can we expect a switch?????!?!

I like the idea, but looks like it's only applicable for low-powered engines. Can't imagine big electrical charger on car, it will draw too much power. Still good idea, but I'd rather see electrical brakes on car (there was an article about those few months back).
As for forums on site, it was one of my comments during the survey period. And i think site can use redesign to make it little more user-friendly, it looks more like blog now.

I love the way it is right now. Like a car magazine that you can leave comments on, and get feedback on.
A forum is ok, but sometimes forums just go on forever and ever. Sometimes it's good when things vanish...

re. site revamp. Homepage layout is A1 Spot on!
Perhaps in the " Home, Reviews, Spy Shots, Supercars, Videos, Contact Us" section there can be a tab "Forum"?
This way we can keep the short topic specific comments focused on a particular article and then have a separate forum section for "meaningful debate/drivel"

Agree 100%.
Please don't change the current format too much...

i want 1 4 my next car which will have a 1.6 diesel with turbo,but will b fitting a hydrogen generator 2 reduce fuel consumption but increase power anyway
