The new Peugeot 308 comes with a new look, features the next generation Stop & Start e-HDi micro-hybrid technology and optimizes fuel consumption and CO2 emissions, which start from 98 g/km. The new 308 will receive its world premiere at the 2011 Geneva Motor Show and will go on sale from April 2011 in Europe.
The second Peugeot model after the 508 (earlier post) to offer the system, the new Peugeot 308 features e-HDi technology on the entry-level diesel 1.6 liter HDi FAP 112 bhp Euro 5 engine. This offer is available with a semi-automatic manual gearbox and, for the first time, with a full manual gearbox.
In addition to micro-hybrid technology, other factors impacting the level of CO2 emissions have been optimized:
- weight reduced by 25 kg on average per car
- launch of 16” tires with Very Low Rolling Resistance
- use of a piloted oil pump on 1.6 liter HDi engines;
- optimization of operation of the alternator on some engines;
- improvement of power steering control (electropump unit);
- Cx of 0.28 for versions with a low fuel consumption.
e-HDi.The new generation stop/start technology is based on the combination of a 1.6 liter HDi Euro 5 diesel engine and a reversible alternator. Relying on an alternator control system (Volt Control) to recover energy during deceleration and a hybrid battery to store and deliver additional energy on startup (e-booster), the HDi unit allows:
- a 15% reduction in fuel consumption in urban traffic;
- a 5 g/km reduction in CO2 emissions for approved cycle fuel consumption;
- 40% faster restarting (400 ms) than with an enhanced starter stop & start;
- activation of engine cut-out from 20 km/h with a manual gearbox (8 km/h for the electronically controlled gearbox);
- increased driveability of the Stop & Start system (silent operation, no vibrations).
The second-generation reversible alternator has a power of 2.2 kW and allows up to 600,000 restarts. The Stop & Start function can be driver deactivated.
Continental AG is supplying Maxwell Technologies ultracapacitor-based booster systems to PSA Peugeot Citroën for the second-generation e-HDi systems. (Earlier post.)
