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.
