The Smart ForFour was developed hand-in-hand with the Renault Twingo and has its engine in the back. Whichever of the three available petrol engines you choose, the Smart ForFour always has its engine under the boot floor. All Smart ForFours come with LED daytime running lights as standard. The mid-range Prime model comes with 15-inch alloy wheels and heated seats. The ForFour has been designed to excel on city streets and boasts a tiny turning circle. The eight-spoke, 15-inch alloy wheels come as standard on all ForFour entry-level Passion models. The entry-level Smart ForFour is the Passion model and starts at just under £12,000. The Smart ForFour is available with a wealth of options, enabling you to give yours a personal touch. The rear seats are easy to access thanks to doors that open very wide. The interior of the Smart ForFour is designed to appeal to younger buyers and it's easy to use. The interior of the Smart ForFour feels well built but the plastic used for the speedometer housing does feel a little cheap, as do other parts of the dashboard. The Passion model offers buyers a choice between black and grey seats (seen here) and black and orange. A rear view camera is available as an option and is displayed on the ForFour's touchscreen. The Smart ForFour comes with automatic climate control as standard. The small petrol engines require you to change gear frequently if you want to keep them in their sweet spots.
