Is mclaren car or lamborghini car fast?

Assuming that you speak of newer models of both brands, I will say this:

The 2012 McLaren MP4-12c has a top speed of 205mph, while the 2012 Lamborghini Aventador is capable of reaching a top speed of 217mph. However, up until the existence of the Bugatti Veyron, the McLaren F1 (older model) was known as the fastest car to ever exist, with a top speed of 241mph. However, at the time, the Lamborghini Murcielago was capable of reaching speeds of 205mph, making the Lamborghini considerably slower.
