I’m not convinced that mild hybrids actually bring anything to the table.
I currently have a mhev and I guess some are different to others, mein charges up when braking or coasting and then gives a boost when needed like when you start going uphill, it also powers the car via the 48v when it enters stop / start as opposed to the 12v and starts it back up instantly.
I would of went for the new FHEV but it has an ags gearbox and isn’t really an auto and is alot slower although it can do a liitle mileage in just ev mode but not much, but it wasn’t for me because of the gearbox.
So i’d say they all help a little to reduce the mpg and co2, but for me it’s the free extra power when needed that it gives the 1.4lt that really helps. I had a golf and when in eco mode it would coast but had no regen and so no boost.
I am pretty impressed after 6 months of the mild hybrid and I don’t drive really economically and use adatptive cruise alot on longer journeys and getting just over 40 mpg combined. I could get better if i actually drove it not on the acc, but it helps me so much. I wouldn’t have a car without it. Plus i guess alot of my daily driving is cold driving, so you also don’t get such great mpg as the engine isn’t at optimum temp.
How would that work also on a bev, if you have no charging at home and so the battery is cold most of the time and as you cannot charge at home. Is it worth preconditioning before you leave, what effect would that have not doing so and just jumping in and driving to school and back in the morning and afternoon.
The Nissan’s E-power is a very intresting one sounds similar to the toyota hybrids which have some amazing mpg although it powers the ev mode only.
My guess is though, Nissan always get a lower mpg than they say alot lower and was the downside to the QQ i had on the scheme, although the ev driving the car might be the answer to that issue and the rear seat belts being very short.
