But now, with the Mazda 3 going on sale and due to arrive in the UK in January, Mazda has decided what it’s going to charge. The starting point for the new Mazda3 will be £16,695 for the 1.5 litre SKYACTIV-G petrol 100ps SE hatchback rising to £23,345 for the diesel 2.2-litre 150ps Sport Nav Auto hatchback.

2014 Mazda 3 five-door revealed

Mazda has gained a fair amount of traction with its fuel-efficient Skyactiv technology, which was first fully implemented in production on the CX-5 compact crossover, followed by the 2014 Mazda 6 midsize sedan. However, unlike the CX-5 and 6, the Mazda 3, the company's best-selling vehicle, only enjoyed a mild Skyactiv makeover for the 2012 model year with the 2.0-liter Skyactiv engine and transmissions being made available on the second-generation model. This meant the 3 would have to wait until an all-new generation debuted to enjoy the entire suite of Skyactiv equipment, including the lighter-weight chassis, body and suspension.

Renault Twin-Z concept (2013) first official pictures

This is the Renault Twin-Z concept (say it 'Twin-Zee'). Although it packs the usual concept car madness of suicide doors, a pared-back cabin and LEDs everywhere, it actually previews the look – and drivetrain – of the next Renault Twingo. The big news is that it'll be rear-engined, rear-drive, and offer an electric option for less money than the £13k Renault Zoe EV.
