    railway line between Florence and Arezzo. A linear array of 21 microphones was positioned at 3.30m from the track, at track level. An accelerometer measured the rail vibration, and a far field microphone was positioned at 7.50m from the nearest railway track, at a height of 1.20m.An optical barrier

    , so the CVT is paying its way. AWD adds about 300 lb to the car compared to the two-wheel-drive version, which comes with a Japanese six-speed automatic. Its EPA figures are 21 mpg city and 29 highway. The car is one of the most comfortable I've ridden in smooth, vibration-free, and solid

  • Dodge Magnum R/T AWD
    Dodge execs may be wincing a bit at their lousy timing. Shortly after they introduced the wonderful 345-hp Magnum, gas prices hit $3 a gallon. Despite the apparent bad timing, the car is not as thirsty at the pump as you might guess from its horsepower rating. For instance, I got about 21 mpg
  • 2003 Cadillac CTS
    21 mpg combined, which is about what I got. Besides having decent straightaway acceleration, the CTS deftly handles twisties, thanks to a four-wheel, multilink independent suspension and antiroll bars, front and rear. The Luxury Sports package also includes TRW Speedpro variable-assist steering

    polyimides, such as DuPontTM Vespel® SP-1 and Vespel®. SP-21 have a history of success in high PV (pressure x velocity) seal ring applications. In figure. 4, diamonds show the pressure and speed relationship from a DuPont field survey of seal rings in. actual commercial transmission applications
