All-new Ford F-150 revealed at 2014 Detroit Motor Show

Ford has revealed an all-new version of the States' bestselling vehicle, the F-150 pick-up – and in a world first, the US favourite boasts an all-aluminium body and lightweight, high-strength steel frame. The new Ford F-150 is more than 300kg lighter than the model it replaces and, thanks to four engine choices including an all-new downsized 2.7-litre EcoBoost turbo, is much more fuel efficient too. Given that Ford sold a staggering 763,402 F-150s in 2013 alone, these changes will have a very positive effect in terms of the new model's environmental impact.

It’s only a few days since Lotus shocked us with details of the all-new Lotus Elite – a 5.0-litre supercharged V8 GT with a folding hardtop, the engine up front, and all-aluminium construction. Now, at the 2010 Paris motor show, the Norfolk firm is unveiling four more cars: Elise, Elan, Esprit and Eterne. On sale in 2015, the Elise is furthest from production, but we already know it will be a radical shift from today’s car.

Chrysler races to upgrade its lineup

In a bid to improve its lineup before a fleet of new Fiat-based vehicles arrives in 2012, Chrysler Group is rushing new features and equipment into 15 reworked vehicles. The equipment, such as a Fiat dual-clutch, six-speed transmission and a new Chrysler V6, will boost fuel economy, improve driving dynamics and spiff up drab interiors, all areas in which Chrysler has fared poorly in consumer surveys. All the vehicles will be on sale by the first quarter of next year.
