Bosch believes vehicles can become even more

Stuttgart/Vienna – Bosch, the global supplier of
technology and services, is confident that the EU fleet emissions targets of 95
grams of CO2 per kilometer are technically feasible. “We are working on
innovative solutions with the aim of further improving engines across vehicle
Further reductions in fuel consumption are possible, but will involve
considerable additional costs in some cases,” said Dr. Volkmar Denner, the
chairman of the board of management of Robert Bosch GmbH with special
responsibility for research and development, at the Vienna Motor Symposium
2013. “From a Bosch viewpoint, it is essential that the further development of
the powertrain be regarded from a cost-benefit perspective.”
In all vehicle segments, Bosch sees technical
potential for reducing CO2 emissions even further, thus protecting the
environment and conserving resources. Even today, compact cars equipped with
the latest technology meet the EU targets.
The most advanced diesel in this
segment emits just 81 grams of CO2 per kilometer. Its gasoline counterpart
manages 99 grams of CO2 per kilometer. In compact cars, the emissions targets
for 2020 are within striking distance, and in some cases already reality.
Improvements to engines can reduce fleet values further.
Especially in the middle class, price is an important
criterion. This is why Bosch is also working to make engines in this segment
even cleaner and more efficient, but at the same time affordable. This calls
for new components. For example, there are systems that can effectively
recuperate braking energy, allowing a mild electrification of the powertrain.
Even in the middle class, therefore, further efforts will allow the very
ambitious EU target for 2020 to be met: modern diesel engines in this class now
emit 105 grams of CO2 per kilometer, and modern gasoline engines 115 grams of
CO2 per kilometer.
systems further enhance premium segment
For many automakers, these developments in compact and
middle-class vehicles make sense. The more economical a vehicle fleet’s
high-volume compact models are, the better they can offset the emissions from
SUVs. In the premium class, simply optimizing the internal-combustion engine is
no longer enough for reaching CO2 targets. Additional savings can be achieved
by further reducing drag and weight.
At the same time, the automotive supplier
Bosch is developing efficient plug-in hybrid systems that make it possible to
drive up to 60 kilometers purely on electricity. Using systems such as these,
even an SUV can reduce its emissions. However, this will also mean that this
vehicle class will cost more. On the other hand, the plug-in hybrid offers
extra functions that further enhance the premium segment. A car equipped with
this powertrain is almost silent when driven electrically, but nonetheless has
the same range as a car with a combustion engine. And the torque of the second,
electrical powertrain provides a boost effect, making the car more fun to
In addition to powertrain electrification, Bosch sees
potential for installing economical CNG engines in all vehicle classes. “CNG
systems can already help reduce CO2 at a low additional cost. In this area,
Bosch components have a technical edge,” Denner said. “However, in order to
increase the market penetration of CNG vehicles, the infrastructure has to be
As the world’s leading automotive supplier, Bosch
offers a broad range of systems and components that contribute to conserving
resources and increasing energy efficiency. With sales of 31.1 billion euros in
2012, the Automotive Technology business sector accounted for 59 percent of
Bosch’s total sales. The business sector counts roughly 177,000 associates
worldwide, of which 33,000 are development engineers.
