Among its many Geneva introductions, BMW will debut the new 116d, now the most fuel-efficient, lowest-emission car in the BMW range. In the EU test cycle, the four-cylinder diesel, which develops maximum output of 85 kW (115 hp) consumes an average of 4.4 L/100km (53.5 mpg US) and offers a CO2 rating of 118 g/km.
BMW will also present medium-term projects in its EfficientDynamics development strategy, one of these being the integration of a thermoelectric generator (TEG) in the vehicle for direct conversion of exhaust heat into electrical energy.
116d. The 2.0-liter, four-cylinder diesel in the 116d is a variant of the 2.0L diesel used in the 118d which improves the fuel economy and emission management.
The special version of BMW’s all-aluminium turbodiesel with common-rail fuel injection delivers its maximum output of 85 kW/ at a speed of 4,000 rpm and reaches maximum torque of 260 Nm (192 lb-ft) all the way from 1,750–2,500 rpm.
Like all models in the BMW 1 Series, this new entry-level diesel comes with EfficientDynamics technologies such as Brake Energy Regeneration, Auto Start Stop, and a Gearshift Point Indicator.
TEG. BMW has been developing a thermoelectric generator for waste heat recovery for a number of years, and has suggested that it may introduce TEGs in the 2010-2014 timeframe in the Series 5.
BMW says that with recent increases in the efficiency of such systems, future use of a TEG may improve fuel economy in practice by up to 5%.
