Electric car speed can compete with the speed of a normal car. If you are talking about a hybrid car, then electric car speed can easily match the speed of a normal car. There are some high-performance models, such as the European-based Fiskars all-electric that claim a very long range and the ability to run at 220 mph. Some of their literature does show this. The Chevy Volt, a real electric with a gas generator on board and the Nissan Leaf, don't claim huge top speeds, but will easily keep up with highway traffic flow. There's also the Tesla coupe, available from the West Coast that claims a top end conservatively in the 80-mph range and a 0 to 60 run of around 4 seconds. They are in production and building their dealer network.
