What is the downside of using regular unleaded gas with 10% ethanol in my 2009 Smart 2for passion ?
I'd like to know that article's source, because many of the issues they bring up were solved a couple of decades ago.There's a reason that premium gas is recommended, for sure. now more than ever, you probably want to use it, to offset the ethanol content. Interesting article on it here. I was unaware of some of the particulars myself. So much for long term storage of such gas...
The problem with ethanol in gasoline - The Globe and Mail
‘The CVT Honda Fit, Achieves better fuel economy. Then a six speed manual transmission one. I‘m surprise, smart didn’t equipped the 453 with a CVT transmission. Instead of the dual clutch.Smark it has a lot to do with the gearing.
Most don’t realize that.
A car can have a different ratio then another which can effect that.
For example my Miata has a final drive of 4.30:1 whereas my rx8 has a 4.77:1(the 8 is geared like that to take advantage of the engine)
Honda, CVT don’t use a torque Converter. the CVT transmission in the Honda uses a wet clutch similar to that found in a standard automatic transmission. While stopped the clutches are all released and there is no transmission of power to the output and CVT belt. To reduce/remove hard shifting the engine power passes through a torque dampener, then to the CVT input shaft. Once throttle speed comes up the drive clutch is energized and begins to apply the clutch locking the engine input to the CVT input shaft. For forward gears there is a clutch that is applied for direct drive to lock the input shaft to the CVT input pulley and belt.True but most don’t like the cvt transmission.
Actually I seen where the cvt isn’t as good as a properly geared manual transmission.
One thing is a cvt uses a torque converter like a regular automatic.
My main problem with it (cvt) is it either keeps the engine wound up near redline or you have no power(had a Dodge Caliber as a loaner) but the fuel economy was ok for the vehicle’s size.
Smart could’ve used it but keep in mind that’s a Nissan tech but if they would’ve allowed them to use it I don’t know(plus customer feedback also makes the difference on the transmission used in a particular vehicle)
