21Stop-start technology to reach 10M vehicles by 2015

We've discussed the virtues of stop-start technology (aka micro hybrid) before and we've even touched on many of the upcoming models that are slated to receive this fuel-saving technology soon, but we never really expected that the stop-start system would become so widespread in application that even vehicles like BMW's vaunted M3 would be scheduled to receive the micro hybrid setup soon.

11Valeo's second-gen stop-start technology coming to 1M diesel Peugeots, Citroëns by 2013

With much of our discussions focusing on hybrid powertrains and the electric cars of tomorrow, we occasionally overlook some of the simpler, efficiency-boosting technologies available today. A prime example of this is the second-generation micro-hybrid stop-start technology from Valeo called i-StARS. Set to debut later this year, the system will initially be featured on diesel-powered Peugeot and Citroen vehicles. A lot of them. Valeo hopes that its i-StARS micro-hybrid technology reaches one mi

15Idling vs. shutting the engine down: how many seconds make a difference?

It's easy to calculate that a car with the engine running but not moving is getting zero mpg. New technologies allow some cars to take control of the on/off switch from the driver when stopped. Whatever their name - stop-start, micro hybrid - automatic systems that shut down a vehicle's engine when the car is at rest help boost efficiency. Automakers - especially in Europe - are happily introducing the technology to vehicles like the Fiat 500 to the Audi A4 and A5 to Ford vehicles that will get

7Which cars in Europe have Stop & Start technology? These do

Stop & Start technology, also known as mild hybrization, is a relatively simple technology that can easily reduce fuel consumption in vehicles. Regular readers already know how it works. Basically, in most instances, the engine shuts down instead of idling, for instance at traffic lights, and stores enough energy to start right back up when the driver presses the gas pedal or shifts into the first gear. This technology can now be found in most car types, and is especially popular in Europe.

2Mahindra hopes micro hybrids make a dent in Indian sales

Letting engines idle away needlessly while a vehicle is at rest is a practice that's definitely on its way out. Some refer to the technology that ends this behavior automatically as stop/start, while others prefer the term micro hybrid. Whatever the case, the underlining technology is the same. The trick lies in making it all work seamlessly and keeping auxiliary bits like the air conditioning compressor and power steering pump working without the power of the internal combustion engine; a small

5Valeo starter-alternator inside new Micro-Hybrid Smart

We are pretty big fans of the stop/start technology that is being implemented by a growing list of automakers lately, as it is a relatively inexpensive way to get some meaningful fuel economy and emissions benefits. The systems can be adapted to many different platforms, because all modern cars are already set up with the components to make it work. The alternators and starters need to be made more powerful, and are combined in the Valeo StARS system, which is going to be standard on the new Sma
