Tips and Trick about Technology of 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 i. 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.

The BMW i8 can accelerate from a dead-stop 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) 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 and Germany.

History

First introduced as the Concept Vision EfficientDynamics, the i8 is part of BMW's "Project i" and it is being marketed as a new brand, BMW i, sold separately from BMW or Mini. The BMW i3, launched for retail customers in Europe in the fourth quarter of 2013, was the first model of the i brand available in the market, and it was followed by the i8, released in Germany in June 2014 as a 2015 model year. Other i models are expected to follow.

The initial turbodiesel concept car was unveiled at the 2009 International Motor Show Germany, In 2010, BMW announced the mass production of the Vision EfficientDynamics concept in Leipzig beginning in 2013 as the BMW i8. The BMW i8 gasoline-powered concept car destined for production was unveiled at the 2011 Frankfurt Motor Show. The production version of the BMW i8 was unveiled at the 2013 International Motor Show Germany. The following are the concept and pre-production models developed by BMW that preceded the production version.

Range and fuel economy

The production i8 has a 7.1 kWh lithium-ion battery pack with a usable capacity of 5.2 kWh and intelligent energy management that delivers an all-electric range of 37 km (23 mi) under the NEDC cycle. Under the EPA cycle, the range in EV mode is 15 mi (24 km), with a gasoline consumption of 0.1 gallons per 100 mi, and as a result, EPA's all-electric range is zero. The total range is 330 mi (530 km).

The production version 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. Under EPA cycle, the i8 combined fuel economy in EV mode was rated 76 equivalent (MPG-equivalent) (3.1 L gasoline equivalent/100 km; 91 mpg-imp gasoline equivalent), with an energy consumption of 43 kW-hrs/100 mi and gasoline consumption of 0.1 gal_-US/100 mi. The combined fuel economy when running only with gasoline is 28 mpg_‑US (8.4 L/100 km; 34 mpg_‑imp) for city driving, and 29 mpg_‑US (8.1 L/100 km; 35 mpg_‑imp) in highway.

The U.S. Environmental Protection Agency's 2014 edition of the "Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends" introduced utility factors for plug-in hybrids to represent the percentage of miles that will be driven using electricity by an average driver, in electric only or blended modes. The BMW i8 roadster has a utility factor in EV mode of 37%, compared with 83% for the BMW i3 REx, 66% for the Chevrolet Volt, 65% for the Cadillac ELR, 45% for the Ford Energi models, 43% for the McLaren P1, 39% for the Porsche Panamera S E-Hybrid, and 29% for the Toyota Prius PHV.
