SUMMARY
Vehicle Makers' Enhanced Goals Improve Business Prospects of Advanced
Automotive Gasoline Engine Technologies
Vehicle makers in North America are setting stiff goals for themselves
regarding their engines' performance and other key characteristics. These
include satisfying emissions regulations, reducing fuel consumption and
manufacturing costs, maximizing reliability, horsepower, and torque, and
minimizing noise, vibration and harshness. Advanced engine technologies help
manufacturers meet these targets. For instance, certain valvetrain
technologies can reduce emissions and fuel consumption even while boosting
performance. Meanwhile, turbochargers and superchargers increase or maintain
power output while decreasing fuel use through downsized engines. Electronic
engine management technologies control engine parameters for best emissions
control, fuel consumption, and performance, while air/fuel systems optimize an
engine's 'breathing'. Gasoline-electric hybrid technologies can save fuel in
urban driving cycles, making gasoline engine-powered vehicles more competitive
than diesel-powered vehicles.
This Frost & Sullivan insight examines the status of North American advanced
automotive engine technologies with a focus on their benefits, drawbacks, and
future trends. The analysis has been segmented into valvetrain technologies,
boosting technologies, electronic engine management technologies, air/fuel
systems, gasoline-electric hybrid technologies, and other advanced engine
technologies.
Vehicle Manufacturers Face a Quandary as Advanced Technologies Increase
Cost, Complexity, and Weight of Engines
Vehicle makers face tradeoffs in their technology choices as they have several
conflicting factors to consider. For example, they have to minimize costs as
well as maximize reliability, while somehow satisfying the customer's
performance expectations, but technologies that reduce emissions and fuel
consumption increase the complexity of engines and often harm performance.
Engine builders evaluate technologies in terms of their benefit/cost
tradeoffs, as they work to find the most effective and market-attractive
technologies to deploy.
Although many customers demand less complexity and easy access to vehicle
parts for maintenance, trends suggest that vehicle powertrains are only likely
to get more complicated in the long term. "More hardware needs to be
incorporated into engines for emissions, performance, and other reasons," says
the analyst of this research. "Aerodynamic and styling requirements can also
dictate packaging volume and hood lines and these needs are likely to cram the
engine compartment more."
Leading Vehicle Manufacturers Drive Uptake of Advanced Technologies by
Incorporating them in Engines
The Japanese 'Big 3' automakers -- Honda, Toyota, and Nissan to a lesser
extent -- have been especially aggressive in incorporating advanced
technologies in production engines for the North American market. BMW and
Mercedes-Benz, two upscale European automakers, have also been at the
forefront of implementing certain gasoline engine technologies. "The North
American domestic 'Big 3' -- Chrysler Group, Ford Motor Co., and General
Motors Corp. -- have largely lagged in adopting most advanced engine
technologies," observes the analyst. "Other, lower-volume vehicle makers
generally position themselves as followers rather than leaders."
