    BMW i8 Production Version speculation based on the test-mule and i8 Spyder concept.
BMW launched the i8 hybrid sportscar which will be for sale in 2014. The mule was tested in Northern Sweden and combined with the images of the i8 Spyder concept it was possible to create a sneak peek of the final production version of the i8 in 2012. The renderings show the i8 with a slightly shorter wheelbase and overall length to reduce weight and to emphasise its sporting & sustainability credentials.
The power output of the production version will be around 399 PS (293kW). The plug-in hybrid powertrain features a gasoline combustion engine driving the rear wheels and a front electric motor fed by a lithium-ion battery that can be recharged from any domestic power socket. The battery charge time is estimated at 1.45 hours.
The electric motor will be responsible for 172 PS (127 kW) with the rest coming from the 1.5L turbocharged three-cylinder unit. The combined peak torque is rated at 550 Nm(406 lb-ft).
The i8 will offer three driving modes: electric, petrol and a combination of the two. The powertrain will be paired with a four-speed transmission which has been designed to extend the performance range of the sports car. This enables it to drive on 3 liter per 100 km (78 MPG) with a top speed of 250 km/h (155 mph).
The kerb weight will supposedly come in at 1450 kg (3197 lbs) which represents a 30 kg weight loss from the original concept and suggests a performance boost when the i8 hits production form. The 0-100 km/h (0-62 mph) acceleration figure is a respectable 4.9 seconds.
The LifeDrive architecture is defined as a fusion of independent functional units: these include a carbon-fiber-reinforced plastic (CFRP) Life module used for the passenger cell and the Drive modules – made primarily from aluminum components – that integrates the powertrain, chassis and safety structure.
Sustainability plays a paramount role in the BMW i concept. It is an issue that runs like a thread throughout the value chain – all the way from purchasing, through development and production to sales and marketing. And when it comes to the efficient manufacturing of its vehicles, BMW i goes a step further still.
The Leipzig production plant will see an additional 70% reduction in water use and 50% drop in energy consumption per vehicle over the years ahead. And the energy that is used will be sourced 100% from renewable sources.
