Most of the current generation electric cars have a single speed transmission. Manufacturers have gone various ways on this front.How about an electric car with a CVT?>
It was an inside joke. More of a location joke, you had to be there.Most of the current generation electric cars have a single speed transmission. Manufacturers have gone various ways on this front.
The 2014 Smart ED is geared such that the relatively lower power motor (55KW) provides spirited driving in the city speeds under 70KM/h. Top speed is limited due to the gearing which makes the motor scream (nicely in fact, sounds great to my ears) at the 145KM/h top end.
Whereas the Chevy Spark EV has a far more powerful motor at 105KW. However, the gearing of the single speed transmission is designed to match the motors maximum 5000RPM. Thus, while the Spark has a massive torque advantage over the Smart, the race to 60KM/h is nearly a draw. Some of that is low rolling resistance tires and traction control limitations.
The Spark EV however is the highest efficiency electric car at the moment. It is comfortable 10% more efficient than the Smart ED. Some of this is down to the design choice of a larger but lower rotating motor and longer gear ratio.
The Smart avoids the use of traction control in dry conditions, yet be nearly the same speed in the city as the far more powerful Spark.
The motor in the Spark EV however is easily able to smoke it's tires. A video on youtube where the traction control has been disabled shows just how traction limited this car is.
In even slightly damp conditions, the Smart constantly hits traction control under full power.
Thus, the design choices of motors and their gearing by the manufacturers have led to a variety of solutions. It is not clear that Smart will feel the need to change their strategy to use a smaller but higher revving motor.
Sigh, i think you misunderstand. Have you lived with a CVT? I have, twice.Sigh, dogs off the line.....I personally know that I need Road Warrior response when I "peel out" on my way to CVS. Doesn't downshift like it should (if you are in Deathrace 2014). For god's sake it's a domestic car that is designed to work well in the traffic conditions the average joe encounters. In this I think I see a clue. Who really NEEDS a king cab 14 mpg, with a shiny hood ornament that will pull two Clydesdales out of a mud hole on a regular basis? Not many....but we like to IMAGINE that we do and need a vehicle that can do the job. "RAM tough....and now gets 21 mpg country"....really?
Know what's really cool? A vehicle that gets really good gas mileage, is extremely reliable, and has enough get up and go to not get you killed when merging. And one that has lots of gadgets, or options for same. Or if you just want basics, just those.
If you want a high performance car....buy one. Stop bellyaching about regular cars that don't do that. Makes you sound like a frustrated car reviewer.:|
