    So if you live in central london and regularly drive to a small town in Hampshire you should walk or cycle? Seems a bizarre sweeping statement to me!

    Problem is Submariner1 those £42k cars also have stop/start fitted. Mind you if you fit Smartop to the SL you can change the default to off

    Just remember that Auto Start/ Stop is demanded by the ENVIROWARRIORS. So if you want real cars, start working to reduce oil prices and shouting down the enviros!

    I heard that manufacturers only fit Stop/Start in order to pass city driving emission tests.

    I seem to be the only one that does not mind stop/start. Its worth a 15% economy gain in city driving which is nothing to sneeze at. Granted the engine/gearbox/electronics/supporting stuff has to be up to scratch to allow it to be reliable but why not.

    But it’s not 15% in real life... and the 15% saving on fuel doesn’t come close to the cost of replacing a timing chain ;)

    It is with my measurements (in central london).

    that is why the the engine/gearbox/electronics/supporting stuff has to be up to scratch

    i doubt that a 4 lt engine properly built can be overstressed in normal use, however if they build it with rubber timing chains and play dough timing gears it might not last as long as its distant quality well built aged cousin from the same stable..... my 17 yr old clk has served me very well and has cost me very little, so much less tech , cant see the much,much prettier sl r230 doing likewise, its just far too complex . which is a real shame as its the best looking car in its class, my opinion..

    If you lived in central London and used the car mainly to go to that small town in Hampshire then the majority of your miles wouldn't be doing all the start-stopping, so you'd fall into the second category and you wouldn't save that much fuel/emissions. Don't get me wrong I've always lived in cities and always had a car, I just haven't used the car to drive around cities when public transport/walking/cycling is there and quicker, cheaper and healthier and much more enjoyable.

    There will always be some exception that people will jump on when it is needed hence I'm not calling for a ban or naything but the fact is that cars in cities are mostly not a great idea, for the driver, residents, environment, community, etc. If they cared about it I wish they'd actually do something about that instead of making all new cars "appear" greener with extra technology and then let them all sit there stopping and starting for hours on end wasting so much productivity/time/petrol for everyone.

    two points

    1) cops hate anything that shows you can already drive (they complain about bikers covering the brake lever (idiots))
    2) I thought was only one thing for advanced porsche driving was if you lift both gear change paddles at the same time (any gear and speed) u lift the clutch - thus one can give it a blip or 3 to get the turbo's spun up, plant the throttle and then drop the paddles for a bit of lively power delivery

    I will be taking my V8 to the City tomorrow, public transport no use as I will be collecting a large number of Ipads, chargers etc so too heavy to carry to the Station. I am congestion charge exempt and have free parking, however if I leave it on I know my stop start will kick in over 20x.

    Sorry but that journey will fall into category 1 and is a typical practical example. No matter how hard you may try to generalise you simply can't and the stop/start is simply another way the "green brigade" are out of touch with reality in my opinion. The only green step I can see may work in the future is electric vehicles once range and regeneration is improved reducing the charge requirements.

    There's always an exception, yes of course I have driven in cities to deliver/pick things up as you should be able to too. That doesn't mean that many journeys in cities for 2 miles for example to drop the kids off to school are necessary. Getting rid of those journeys would mean almost all emissions go, reclaimable road space for pedestrians/parks and no congestion when you do have to pick up some ipads and people would be less obese. It would do a lot more than gimmicks like start stop technology.

    I'm lucky to have spent my last 7 years in 2 cities where cycle lanes are everywhere (and proper seperated from road type stuff), a journey anywhere within the city on any form of public transport is 1€ and the "boris bikes" are free to use for a subscription of 20€ a year. There's also not this health and safety culture of "your kids are going to die if they don't get driven directly to the gate in a big 4x4" so the kids walk to school.

    In one city, Barcelona, the lack of traffic and generally good quality of life hasn't been enough so they've now put some huge low emission zone over the whole urban area to ban older diesels. It hasn't made much difference other than penalising the poor and getting people to buy new cars they can't afford. In the other, Valencia where I luckily live now they've created 4 main "axis roads" which are vital and have traffic lights that are coordinated and stay red/green for a very long time so you stop once and drive 2miles without having to stop again, and you do that 3 times in total to get through the city. Then they've started a campaign of reclaiming road space and parking from all other roads off this and bit by bit putting trees/cycle lanes/pedestrian only zones and reducing the car carrying lanes. It seems to work as in people can get around to the main motorways on the axis points but noone considers taking their car for journeys within the city. It's also just really nice to walk around any time of day where there is no traffic (except the axis roads).

    So the problem can be solved without LEZ and the rest and mainly to impriove quality of life. FWIW I'm not concerned about emissions - I drive a 1987 3.0 diesel with no catalyst; but I don't drive it around the city because I can't be bothered to walk/cycle for 10 minutes because that would be detrimental to mine (and others) quality of life
