Toljatti can be accessed in a 2 hour drive from Samara, to which it is linked by a motorway.
Beware of potholes and frequent controls by the police. But overall the drive is ok and does not pose a real problem, given you have bought the combined city map of Samara and Toljatti, which can be purchased in Samara.
Toljatti consists of two major parts. At the northern edge of the new part of the city - which is located to the north-west of the old one - is located the Lada car factory. According to some guide books it is the world´s biggest.
