Advanced Low Temperature Diesel Combustion: Low Emissions and Better Fuel Economy

Survey: 75% of UK Drivers Would Buy a Car with Stop-Start System

Three out of four UK drivers would buy a car with a stop-start system, according to the latest survey of motorists by Motorpoint, the UK’s leading car supermarket group.

Fuel costs saving of up to 8% in urban driving is the top reason voiced. Only Citroën, BMW and Mini are offering stop-start on non-hybrids. Most manufacturers are expected to introduce stop-start, on both manuals and automatics, over the next few years—either across the range or on designated “green” models.

In these days of increasing fuel prices and demands for lower CO2 emissions, its surprising that this tried and tested technology isn’t already more widespread. We always maintain a mix of stock that offers our customers what they tell us they want. This survey shows an overwhelming vote in favour of stop-start technology. We already stock new and nearly new Citroen, BMW and Mini models and we shall make sure, as more manufacturers make the technology available, that we stock those cars too.

—Paul Winfield, Motorpoint operations director



I'm shocked these systems haven't become more widespread.


I also don't get it. It seems like such a simple solution. It provides one of the key benefits of a hybrid without as much added cost or weight.


I would legislate for them europe wide.
The trick is to frame the legislation to define the benefits you want to deliver rather than how to do it.

The question is - what benefits do you want ?

Lower fuel consumption.
Lower pollution in stationary traffic.
Lower pollution in slow traffic (mission creep here).
Lower GHG output.

Or do you just say - stop the engine in stationary traffic.

Or do you just hope the 130gms/km limit will cause it to happen as a by product ?

You don't want to force all cars to go (micro) hybrid, but you want to reduce fuel consumption and pollution.


Since there was no mention of price what would stop the other 25% from purchasing a vehicle with a stop/start system? Fear of wearing out their vehicle? Expected increase in cost (though a specific increase was not mentioned)? Other beliefs which may be true or untrue?

If I were commissioning the survey I'd like to go back and run a second one addressing the 25% who would not buy to find out what their main concerns are...


When you look at the article about lubrication for transmissions in start/stop you start to see that it may not be that easy to get reliability and longevity. The starter on my car might cycle 1000 times per year and last 10 years. Now you can increase that a factor of 10 and what happens?


sic: An ordinary starter & generator are not designed for the requirements of a start-stop system; combining the two, and getting rid of the belt, would actually save at least one external aggregate. The BHS system of GM is really one, I would be worried about the longevity...

Also noteworthy, the UK is (together with NL) the country with the highest fuel prices in the EU, and no artificial price skew towards diesel as in most other EU countries (lower taxes on diesel fuels).

The added cost of an integrated Start/Stop system are in the order of less than 200 EUR. A higher vehicle price in the order of 500 EUR would pay off after about 2 to 3 years, assuming 15 000km/a and a fuel consumption reduction of only 5%.

And yes, it's sad - but then, what is the percentage of Start-Stop equipped cars sold in the US currently?


"..stop-start on non-hybrids."

This implies that it is not a BAS system, which is referred to as a "hybrid". The devil is in the details. If they are going to try to keep costs down by just using a regular starter and transmission control, I would have to wonder. They make NO mention of any alternator, let alone combining the starter and alternator.
