New (2014) Mazda 3 revealed – no prices yet

The new Mazda3 (pictured) arrives – and it looks good. The Mazda3 is already a better car than its sales would suggest, and the all new Mazda3 looks to be even more competition for the Ford Focus and VW Golf than ever before. Perhaps the only complaint about the Mazda3′s design is that it looks a bit too much like a shrunken Mazda6, but that’s a bit like moaning the DB9 looks like the Vanquish (well, the Mazda3′s not that good looking, but it makes the point).

Electric Fiat 500e costs the same as 500 Pop – in the US

Sergio Marchionne reckoned Fiat would lose £7k on every 500e they sell, but that may be a very conservative estimate judging by the deal Fiat has put together for the 500e in California, where it’s just launched. For a very modest down-payment of £650 and then £130 a month, you can drive off in a brand new Fiat 500e. That’s exactly the same deal Fiat offers on the 500 Pop – a car that cost under £10k in the UK – making the 500e the first EV we’ve come across where costs are sensible.

BMW i8 production car revealed – costs £99,845: Frankfurt 2013

The new BMW i8 Hybrid (pictured) will cost £100k in the UK The BMW i8 jas finally arrived in production guise at the Frankfurt Motor show, neatly creating the top end of BMW’s new i-brand range after the BMW i3 underlined the starting point. Looking really quite appealing, the i8 uses the same carbon fibre reinforced plastic bodyshell and aluminium chassis construction as the i3, but whereas the i3 is built to be a city car, the i8 is the closest we’re likely to get to a 21st century version of the BMW M1. Similar in size to the Audi R8, the BMW i8 is a 2+2 with a 3-cylinder 1.5 litre engine and generator sitting at the back and driving the rear wheels and an electric motor at the front driving the front wheels, with a petrol tank at the back and the batteries for the electric motor stored in the centre tunnel.
