BMW is currently working to launch a facelift for its i8 model by end 2017. The hybrid sports car will get upgrades in powertrain, chassis and overall design. While the current 1.5-litre turbo petrol mill coupled to an electric motor generates 362hp, the updated combination is likely to churn out 425 horses. This is approximately 18 per cent increase in power. The German carmaker is likely to introduce the induction charging option also in the facelift. Apart from this, it will focus on weight reduction by using carbon-fibre tyres instead of aluminium ones.
