The 15 most significant cars of the 2011 Frankfurt motor show

Over 100 new cars were unveiled at the 2011 Frankfurt motor show, but which are the most important? From production cars to concepts that will never be built, CAR's road test editor Ben Pulman, decides on the 15 most significant models premiered at the IAA...  1 – Land Rover DC100 concept Chunky and funky, it’s Land Rover’s Evoque, the Defender urbanised, modernised and stylised for the 21st century. Range Rovers have become too ‘bling’, but the DC100 has the restrained elegance of the Disco 3 – we’ll ignore its bright yellow sister, the speedster-style DC100 Sport.

Hyundai i40 Hybrid & i30 CNG: Paris 2014

The Hyundai i40 Hybrid & i30 CNG on the floor in Paris Hyundai is busy trying to find ways to reduce emissions and increase economy – just like every other car maker – and has arrived at the Paris Motor Show with a pair of economy-focused models – the Hyundai i40 mild hybrid and an i30 running on compressed natural gas (CNG). The Hyundai i40 gets a 48V mild hybrid setup just like the Kia Optima-T Hybrid, which means a 48V lead-carbon battery which cuts emissions from the 1.7 litre diesel by up t0 20 per cent by allowing electric-only running at low speeds and when cruising and, just like the Optima, the i40 hybrid gets a belt-driven starter generator for seamless restarting, which also contributes to engine power in normal running. The beauty of the system – apart from improvements in economy and emissions – is that it’s very light compared to a full hybrid – just 46kg – and costs 75 per cent less than a full hybrid system to install.
