5 second 0-60 for the Leaf!?

A comment: ~200 ft-lbs for ~2800 lbs would require rather perfect CVT gearing (holding peak power during the accel run), and I still think this would just be too much car to move this quickly with only a 80 kW motor. Correct me if my #s are wrong.

Additionally, the wheel and tire package on the leaf doesnt look like it could provide the traction for a 5 second run w/o spinning, so there could be a problem getting the torque to the ground anyway.

Having a nissan and a prius, I am a fan here, but I call bogus. Maybe 7 seconds. It's not a Tesla.

 

atroader: there's no need for a gearbox on an EV. The purpose of the gearbox on a regular car is to multiply up the torque, because a spark engine produces its maximum torque with a fully-open throttle which is generally only possible at moderately high revs. The electric motor produces maximum torque at switch-on and is only really limited by how much power it can handle.

The spec sheet gives the Leaf's motor a maximum torque figure of 280Nm (206.5 lb.ft), but this may well be multiplied up by fixed gear ratios before getting to the road.

The early Tesla Roadsters have a gearbox but it's stuck in first gear. Newer ones only have a single ratio.

The tyres clearly must stick far better than you might think, because stopping times are usually way faster than accelerations. (OK, for stopping, drag helps you while you must overcome drag when accelerating, but even so, the tyres have to cope with the force going through them.)

 

With the HP of 110 and the weight at 2800lbs a normal ICE car would do 9-11 seconds. Even with 100% torque at zero I would not imagine better then 8 seconds, and that would be pretty good.

A V6 Mustang 2005-2009 is 6.9 seconds. My 2004 is 8.6 seconds. Could my new Leaf be FASTER then my current Mustang?

 

5 second 0-60 for the Leaf!?
That would be nice, then I could beat my wifes SRT-8 Challenger to at least 60.

 

Performance Statistics: 0-60 mph

My Nissan Maxima '98 is 7.6 Sec - and thats what I'd expect.

 

These speeds are possible in small EVs but not sure if the leaf will be in that category. The entire sports car industry will be shaken up in about 5yrs when guys are running little EVs like a leaf and doing 0-60 in 2.5 seconds. You'll have guys in $30,000 EVs beating a Bugati Veyron.. Top Gear will not be amused hehe..

 

You are exactly right! No one ever thought they would see Honda Civics pushing 500 HP to the front Wheels.. We are going to see some cool and exciting mods when the Fast and Furious crowd take time from playing Xbox to break out the laptops and go to work on the EV Rockets! Can't wait to see Jeremy and the boys at TG Smoking the front tires around Hammerhead...

Well, Automobile.com sure isn't coroborating the "sub-6 seconds" time:

2011 Nissan Leaf Preview

It aint the 1st dope that CBS has smoked. After all, the TESLA does 5.6 seconds from 0-60.

 

Maybe that is how they came up with that number, they used the Tesla number accidentally.

 

i'd say 10.5 seconds or so. sure, 0-20 will be fast, 20-40 will be acceptable, but 40-60 will take a while. and 60-100? slow. the volt/ampera has 112k, and that's been quoted as "sub ten seconds".

 

Here's a British Leaf proto type report :
Industrial Laser Solutions Wire News Display - OptoIQ your destination for the latest information on optical technologies and applications

Estimates are approx. 8 sec 0-60...

 

i think they misquoted... its 0 to 60 KILOMETERS per hour in 5 secs.

after all, the only real ones (besides the ultra secret ones in the US) are in Japan. they run metric there. besides at the Leaf Tour, it was said that it would accelerate "like a typical 6 cylinder".

Page 34 of this document said 0->30mph in ~3.9 seconds. It also said 25->37mph in ~2.2 seconds.
