PARIS -- PSA/Peugeot-Citroen has chosen Robert Bosch to supply the key technologies for its diesel-electric hybrid cars. "

PSA's head of purchasing, Jean-Christophe Quemard, said the carmaker is forming a strategic partnership with Bosch for the diesel-electric powertrains.

PSA plans to launch its first production diesel hybrids in 2011. These include an SUV based on the Peugeot Prologue concept unveiled at the Paris auto show in October, a large sedan and other unspecified cars.

Diesel hybrids likely will cost about €4,000 to €5,000 more than a comparable diesel, said PSA's director of hybrid and electric programs, Eric Breton.

Some carmakers, suppliers and analysts suggest that consumers will not pay more for diesel hybrids.

But pressure from the EU to cut average CO2 emissions from new cars to 130 grams per kilometer between 2012 and 2015 from 158g/km now could help PSA sell more diesel hybrids.

High price for hybrids 

"Diesel hybrids will always be expensive because you have two costs -- the cost of diesel and the cost of hybrid technology," said Jean-Philippe Le Denmat, a powertrain and research specialist with analysts Global Insight.

"PSA is betting that high CO2 taxes and high gasoline prices will justify the cost," he said.

PSA's Prologue-based diesel-hybrid crossover will have CO2 emissions of 109g/km and will use about 30 percent less fuel than a diesel car. The crossover will have a 200hp 2.0-liter diesel engine driving the front wheels and a battery-powered electric motor driving the rear wheels.

Analysts remain skeptical of PSA's long-term volume plans.

Said Global Insight's Le Denmat: "We don't think a brand like Peugeot, which is not a premium brand, will get very high sales volumes in the near future from this diesel hybrid, which will remain quite expensive for some time."

Bosch will supply the electronic controllers and electric motors for the French automaker's HYbrid4 diesel-electric powertrain.

巴黎——PSA/标致雪铁龙集团选择了罗伯特博世为其柴电混合动力汽车提供关键技术。

PSA采购部门的负责人Jean-Christophe Quemard说，汽车制造商与博世在柴电动力方面形成了战略伙伴关系。

PSA计划在2011年推出其第一款柴油混合动力汽车。这其中包括于10月的巴黎汽车展上发布的以SUV为基础的标致Prologue概念车、一款大型轿车和其他一些未确定的汽车。

“柴油混合动力可能将比柴油多花费约4000至5000欧元，”PSA混合动力和电力项目主管Eric Breton说。

一些汽车制造商、供应商和分析师指出，消费者不会为柴油混合动力车而支付更多钱。

但是，压力来自欧盟对于新汽车平均削减二氧化碳排放量的规定——在2012年至2015年间要从现在的158g/km降至130g/km——这可以帮助PSA销售更多的柴油混合动力车。

混合动力汽车的高昂价格

“柴油混合动力将一直是很昂贵的，因为你有两部分成本——柴油的成本和混合动力技术的成本，” Global Insight的分析师、传动系统研究专家Jean-Philippe Le Denmat说。

“PSA在赌注二氧化碳的高额赋税和汽油的高价格将会决定成本，”他说。

PSA 的Prologue柴油混合动力crossover车型的二氧化碳排放量为109g/km，并且比普通的柴油车少消耗30%的燃料。crossover车将会有一个200hp马力、2.0升前轮驱动的柴油发动机和一个电池供电的电动马达驱动后轮。

分析师仍对PSA的长期出货量计划持怀疑态度。

Global Insight的Le Denmat说：“我们不认为像标致这样一个不算优质的品牌，在不久的将来会从柴油混合动力上获得非常高的销量，而柴油混合动力在一段时间内仍将保持相当昂贵。”

博世将会供应法国汽车制造商的HYbrid4柴油发电机动力系统中的电子控制器和电动马达。
