The future keeps all options open: each powertrain technology has its specific advantages and, when applied appropriately, can optimally enhance its strong points. Whether diesel, gasoline, natural gas or electric drive, Bosch is consciously and permanently developing its powertrain portfolio. The goal is to better coordinate the technologies used under the hood, thereby achieving maximum efficiency and further reducing emissions.
Combustion engines will remain the most widespread powertrain system for the foreseeable future. They are very reliable and can cover long distances. Innovations can make them even better: Bosch is developing solutions that make combustion engines more efficient, more economical, and eco-friendlier.
Hybrid systems integrate the advantages of fuel-saving injection systems with electric powertrains, which can boost a combustion engine as needed. The wide selection of powertrain solutions from Bosch range from low-voltage entry-level hybrid systems to powerful high-voltage and plug-in systems.
Vehicles equipped with Bosch electric powertrains are eco-friendly, quiet, and highly efficient. They also offer an extremely dynamic and enjoyable drive. The wide range of Bosch powertrains includes systems for passenger cars, light trucks, light electric vehicles, e-scooters and e-bikes.
Bosch creates the software platforms needed to interconnect charging stations, vehicles, providers of mobility services, and users. These platforms make it easy to find, reserve, and pay for charging stations online. This also paves the way for new services and business models.

There is consensus in one area: emissions need to be reduced to achieve better air quality. But emissions such as particulate matter and nitrogen oxides have many origins. And road traffic is by no means the only source. The best way to achieve sustainable improvement is to reduce emissions as much as possible in all areas. For this reason, Bosch is pursuing a vision of mobility which is as emission-free as possible. The approach taken by Bosch is to envisage mobility as a holistic concept – solutions based on automotive technology and even beyond the car.
Bosch applies its extensive expertise in countering the complex causes of poor air quality. This includes continuous improvement of the existing product portfolio as well as new developments of innovative technology, digital services, and new mobility concepts. These include technical solutions for the powertrain, braking, connectivity, and measurement of immissions which supply valuable data for optimized traffic management.
Bosch has optimized the combination of diesel engine, exhaust gas recirculation and exhaust gas treatment to such an extent that nitrogen oxide emissions by diesel vehicles can be reduced significantly in daily road traffic. In test vehicles, interventions in engine management and the use of modified components in the air and exhaust gas system, among other things, have helped to realize considerably improved temperature management. This is a major contribution toward reducing the NOx emissions in road traffic to very low values.
The gasoline engine still harbors a great deal of potential.
Port fuel and direct gasoline injection are two modern fuel injection systems that are offered by Bosch. These can be combined to an innovative gasoline fuel injection system where the strengths of the respective sub-systems are mutually complementary. This gives rise to a variety of advantages in terms of fuel consumption and emissions: port fuel injection presents specific advantages during partial-load operation with low friction losses and an optimal fuel mixture, while gasoline direct injection features a considerably higher knock limit at high engine loads. In combination, these two technologies support additional reduction of particle emissions.
Urban roads are now being used by more and more electric vehicles – from small scooters to vans, trucks and even off-highway vehicles. This will considerably relieve urban air as electric vehicles do not emit any local air pollutants.
Vehicles with a fuel cell-electric powertrain can drive several hundred kilometers on a single tank – and entirely without local CO2 emissions, just like battery-electric vehicles. Bosch has already achieved great progress in the development of fuel cell-electric drives for heavy-duty commercial vehicles and will also be increasingly deploying this technology in passenger cars in the future. As a system supplier, Bosch already avails of extensive expertise in the area of fuel cell technology and offers a comprehensive portfolio of easily integrable components and fuel cell solutions for trucks and cars.
Bosch is consistently further developing the natural gas powertrain for the growing number of CNG vehicles worldwide. This includes systems and components for fuel supply, fuel injection, and engine management. The comprehensive portfolio of natural gas technology can be used for many different types of gas engines and vehicles: from compact cars to heavy commercial vehicles. Compared to liquid fuels, natural gas generates significantly lower CO2 emissions and burns practically particle-free.
Stop-and-go, traffic jams and diversions – traffic invariably causes significantly more emissions than implied on paper. Connected services make driving a digital experience while also contributing toward improved air quality by helping drivers to reach their destinations without any traffic-related obstacles.
Bosch is continuously improving the range of digital mobility services and connecting vehicles to the environment. This interplay gives rise to a new breed of mobility solutions for a more environment-friendly future.
From parking search to the actual parking maneuver – automated valet parking is a convenient service offered by Bosch.
As a pioneer of automated mobility, Bosch has developed a driverless system that employs connected technology to save drivers not just the wearisome search for a parking space, but also the parking maneuver itself. This is made possible thanks to communication between Bosch technology in the parking garage infrastructure and vehicles themselves. Automated valet parking does away with unnecessary searches inside a multi-floor parking lot – the vehicle finds its own way to the vacant space.
Always up to date: the connected horizon from Bosch supplies real-time data on road conditions and traffic volumes.
The connected horizon from Bosch supports drivers by providing up-to-date information on the route ahead, thereby ensuring safe, assured and more economical driving. This connected driver assistance system links static and dynamic map data with the latest traffic information and proactively provides the driver with information relating to speed limits, bends in the road, danger spots, and the tail end of traffic jams. With this information advantage, drivers can adapt their driving style accordingly in order to minimize the risk of accidents or reduce fuel consumption.
Air quality in urban environments is also impaired by road and tire wear particles as well as brake dust. This means that emissions not only arise during acceleration but also while braking. Accordingly, around half of the particle emissions in road traffic are attributable to wear by brakes, tires, the clutch, and the road surface, approximately half of which is in turn accounted for by brake dust*.
For this reason, Bosch is also focusing on the braking process in an effort to enable more environmentally-friendly driving right across the board. The innovative iDisc brake disc and regenerative braking systems in hybrid and electric vehicles contribute toward improving the quality of air in urban environments.

With the Bosch iDisc, the amount of particulate matter generated during braking is reduced by up to 90% compared to conventional brake discs.
With its iDisc brake disc, Bosch helps to alleviate the particulate-emission problem in urban environments. The iDisc generates up to 90% less brake dust than a standard brake disc. The coating of the iDisc also reduces brake disc wear and improves operating safety. The iDisc is suitable for all types of vehicles – from passenger cars to commercial vehicles, whether with combustion engines or electrified.
For electric vehicles, the iDisc represents an additional advantage: these vehicles use the electric generator brake to decelerate the vehicle and for recovering energy (recuperation). As a result, the friction brake is applied less often, which can lead to rust formation on conventional brake discs. The iDisc is not affected by this problem as its coating does not rust.
Regenerative braking systems permit energy recovery, thereby increasing the range of electric vehicles.
The regenerative braking systems from Bosch are of key significance for hybrid and electric vehicles. Bosch therefore improves the range of electric vehicles and reduces emissions of brake dust in vacuum-independent regenerative brake systems by more than 95% at the same time. During emission-free generator braking, the electric motor recovers some of the energy which is then stored in a high-voltage battery for reuse. With a conventional braking system, much of the kinetic energy is released unused into the environment.
