No problem. As with any car, they will vary.
The LEAF, which is the commuter level car I have, will go 0 to 60 in about 7 seconds. It's said to top out over 90 mph. I run about 70 mph without a problem on the freeway. It's comparable to a Civic, Camry or something like that.
The Tesla Roadster, an all electric sports car, will go 0 to 60 in under 4 seconds.
As with most things, it depends upon what you're willing to spend and what you really want. Tesla is marketing their Model S, which is a luxury sedan that will go 0 to 60 in about 4 seconds, and 300 miles on a charge. I haven't seen one in real life, but they look pretty nice.
When you get into performance, though, you're talking about intangibles, as well. What I mean is, driving an EV is not exactly the same as driving a gas car. The acceleration is smooth. No gears to shift. There's also no power band in an EV. The torque is consistent throughout the RPM range, so that acceleration off the line is considerable, and continues all the way through. It's also very quiet.
Now... you might not like either of those things. Driving a Tesla Roadster wouldn't be anything like driving a Mustang. In the same vein, driving a BMW M3 is nothing like driving a a Mustang, either.
