Information on the Volvo B5254F engine.

The demands on the car of the 90’s are very high in every respect. As vehicle manufacturer one can no longer concentrate only on a subset of all properties. To gain success, excellence is required in all areas. Furthermore, the customer of the 90’s will not accept having to adapt himself or herself to the vehicle. The vehicle must instead be adapted to man. This makes it necessary to study manmachine interactions when developing
a new car.

These demands, coupled with the many properties affected by engine characteristics, create the need for a
property oriented development process where the combination of all properties are taken into consideration from the very beginning.

Every customer expects good comfort, good performance and fuel economy from their car. This in turn, places a demand for effective and efficient
technical solutions; to choose, as Volvo sees it, the best solution for each specific purpose.

The challenge for Volvo consequently meant to combine a roomy interior with a solid safety structure, compact exterior dimensions and effective energy absorption with a powertrain combining comfort, performance and energy efficiency.

A transverse installation of an inline engine is today accepted as the best technical and most space efficient
solution. This is a solution already chosen for the Volvo 400-series and was on space, packaging and handling
grounds also chosen for the Volvo 850

The development of the new engine is the second step of Volvo’s new modular engine family, the N-series.
The first step was the in-line six B6304F, which was introduced in the Volvo 960 in August 1990.

Since a lot of emphasis during the development of the Volvo 850 was put on performance and driving
pleasure, this had its effect on the internal relationships of the four properties given priority. In order to meet
the performance requirements with maintained fuel economy, a variable induction system was introduced.
This made it possible to combine high torque at low engine speeds with high power at high engine speeds,
keeping fuel consumption optimized.
