Smart ForTwo

First launched in 1998 as the MCC Smart City Coupe, the ForTwo has been redeveloped as it moves towards the North American market. Length has increased from 2.5m to just under 2.7m - for greater crash protection and more trunk space, which now stands at 340 liters when packed to the roof. Regulations have also seen the IP straightened out, though the prominent air vents remain.

Hyundai Elantra

Hyundai is set to add another vehicle to its list of successes: the new Elantra, which was revealed at the LA auto show this year. Created by principal designer Cedric d'Andre, the Elantra was the last car conceived under the direction of Hyundai's former design boss, Joel Piaskowski. The new car shares the 'fluidic sculpture' design theme of its larger sibling, the Sonata and has an impressively low 0.28Cd.

Suzuki refreshes Swift with five-door Sport and 4x4 model

Suzuki is offering its cracking little warm hatch, the Swift Sport, with five doors for 2013. The family-friendly model shares its powertrain with the three-door Swift CAR ran (and loved) as a long termer last year – that means a naturally aspirated, 1.6-litre engine good for 134bhp, a six-speed manual gearbox and 0-62mph in 8.7sec. Suzuki says it expects one-third of Swift Sport customers to opt for the five-door model – sales have so far averaged 1200 a year in the UK.
