This characteristic has made the inline six popular in some European sports-luxury cars, where smooth high-speed performance and good fuel economy are desirable.

However, this increase in high-speed performance came with a trade-off - the planes were not very effective or efficient at lower speeds.

The engine capacity has been expanded to 660 cc (in 1990) to aid high-speed performance and the increased weight of new safety equipment.

Lately, said Eklund, he has achieved the sort of high-speed performance that first attracted the Flyers.

This all happened during 1926, with high-speed performance as the primary goal.

The H.V.40 flew well but had poor high-speed performance and was only used for a number of training flights.

This characteristic has made the straight-six popular in some European sports-luxury cars, where smooth high-speed performance is very desirable.

In 1965 Lowrance introduced the first sonars and transducers capable of high-speed performance.

Obviously the forcing resistance is one of the fundamental factors influencing high-speed performance so this relationship is given further consideration in the next section.

This car features a unique rear-end appearance and smooth high-speed performance.
