BMW i8
The BMW i8 is a plug-in hybrid sports car developed by BMW. The i8 is part of BMW's electric fleet "Project i" being marketed as a new sub-brand, BMW i8. The 2015 model year BMW i8 has a 7.1 kwh lithium-ion battery pack that delivers an all-electric range of 37 km (23 mi) under the New European Driving Cycle. Under the United States Environmental Protection Agency cycle, the range in EV mode is 24 km (15 mi) with a small amount of gasoline consumption. Its design is heavily influenced by the BMW M1 Homage concept car, which in turn pays homage to BMW's last production mid-engined sports car prior to the i8: the BMW M1. BMW ceased production of the BMW i8 in April 2020.
The BMW i8 accelerates from 0 to 100 km/h (62 mph) in 4.4 seconds and has an electronic limited top speed of 250 km/h (155 mph). The BMW i8 has a fuel efficiency of 2.1 L/100 km (134.5 mpg‑imp; 112.0 mpg‑US) under the NEDC test with carbon emissions of 49 g/km. The EPA rated the i8 combined fuel economy at 76 MPGe (3.1 L gasoline equivalent/100 km; 91 mpg-imp gasoline equivalent) and 29 miles per gallon (6.7L/100 km) when running in pure gasoline mode (after the battery is drained empty).
The initial turbodiesel concept car was unveiled at the 2009 International Motor Show Germany. The production version of the BMW i8 was unveiled at the 2013 Frankfurt Motor Show. The i8 was released in Germany in June 2014. Deliveries to retail customers in the U.S. began in August 2014. By early November 2016 global sales since mid-2014 totaled more than 10,000 BMW i8s, making the i8 the world's top selling plug-in electrified sports car. The top selling markets are the United States, the United Kingdom, Germany, China and Canada.
BMW i8 Concept
The BMW i8 Concept plug-in hybrid electric vehicle includes an electric motor located in the front axle powering the front wheels rated 96 kW (131 PS; 129 hp) and 250 N⋅m (184 lb⋅ft), a turbocharged 1.5-liter 3-cylinder gasoline engine driving rear wheels rated 164 kW (223 PS; 220 hp) and 300 N⋅m (221 lb⋅ft) of torque, with combined output of 260 kW (354 PS; 349 hp) and 550 N⋅m (406 lb⋅ft), a 7.2 kWh (26 MJ) lithium-ion battery pack that allows an all-electric range of 35 km (22 mi). All four wheels provide regenerative braking. The location of the battery pack in the energy tunnel gives the vehicle a low centre of gravity, enhancing its dynamics. Its top speed is electronically limited to 250 km/h (155 mph) and is expected to go from 0 to 100 km/h (0 to 60 mph) in 4.6 seconds. Under normal driving conditions the i8 is expected to deliver 80 mpg‑US (2.9 L/100 km; 96 mpg‑imp) under the European cycle. A full charge of the battery will take less than 2 hours using 220 V. The positioning of the motor and engine over the axles results in optimum 50/50 weight distribution.
The vehicle was unveiled at the 2011 International Motor Show Germany, followed by CENTER 548 in New York City, 42nd Tokyo Motor Show 2011, 82nd Geneva Motor Show 2012, BMW i Born Electric Tour at the Palazzo delle Esposizioni at Via Nazionale 194 in Rome, Auto Shanghai 2013.
BMW i8 Concept Spider
The BMW i8 Concept Spider included a slightly shorter wheelbase and overall length over the BMW i8 Concept, carbon-fibre-reinforced plastic (CFRP) Life module, drive modules made primarily from aluminium components, interlocking of surfaces and lines, 8.8-inch (22.4 cm) screen display, off-white outer layer, orange tone naturally tanned leather upholstery.
The vehicle was unveiled in Auto China 2012 in Beijing and won Concept Car of the Year, followed by 83rd Geneva International Motor Show 2013. The designer of the BMW i8 Concept Spider was Richard Kim.
The design of the BMW i8 coupe prototype was based on the BMW i8 Concept. The BMW i8 prototype has an average fuel efficiency of less than 2.5 L/100 km (113.0 mpg‑imp; 94.1 mpg‑US) under the New European Driving Cycle with carbon emissions of less than 59 g/km. The i8 with its carbon-fiber-reinforced plastic (CFRP) passenger cell lightweight, aerodynamically optimized body, and BMW eDrive technology offers the dynamic performance of a sports car, with an expected 0–100 km/h (0-62 mph) sprint time of less than 4.5 seconds using both power sources. The plug-in hybrid system of the BMW i8 comprises a three-cylinder, 1.5-liter BMW TwinPower turbo gasoline engine combined with BMW eDrive technology used in the BMW i8 and develops maximum power of 170 kW (228 hp). The BMW i8 is the first BMW production model to be powered by a three-cylinder gasoline engine and the resulting specific output of 115 kW (154 hp) per liter of displacement is on a par with high-performance sports car engines and is the highest of any engine produced by the BMW Group.
