Do hybrids or electric-powered cars have as much power as gas-powered cars?
Some auto makers chose to boost the power of their hybrids and keep the mileage the same as the standard engine version (quicker 0-60) and many chose to use the efficiency to increase mileage. They all benefit from regenerative braking where the energy from the car goes back into the battery as the car is slowed down by the driver using the brakes.
It depends on the car, and the mechanicals used. Electric motors have a lot of torque for their size, so they can give the car a kick. Most hybrids I know of at the moment use a small gasoline engine augmented by an electric motor. The gasoline engine is used for driving the car and charging the battery that powers the motor. The electric motor can run with the gasoline engine off, or in conjunction with the gasoline engine. The Toyota Prius, for example, has the same engine as an Echo (Yaris), with an electric motor attached. The electric motor in it has a maximum torque of 400Nm. To give you an indication, that’s the same as a Dodge Viper from the mid 90’s. Partly because of that, the Prius has traction control. The gasoline motor has around 85kW (IIRC), which is comparable to most small gasoline powered cars.
The primary motivations for bringing hybrids and electrics to market are emissions and economy, so they are mostly small and underpowered to deliver the best economy and ecology. There is no technical reason why they could not be over-powered, but there is no market for that since it is cheaper and better by most measures to just use an efficient gas engine and not deal with the added complexity. There are probably conventional vehicles with less power than the electrics and hybrids on the market.
