What are the Nascar speed records. Sorry about the bad english.?

May be...

I wan't to know first the highest speed a Nascar Truck can get. And the "common" Narcars can do too.

Thanks for the comprehension.

Bill Elliot ran 210 at Daytona and 212 at Talladaga in 1985. Record will likely stand forever.

The highest closed circuit speed for a NASCAR was a Rusty Wallace test lap without the restricter plate at Talladega Speed way he had a lap average of 216 mph. Bill Elliot holds the official record at 212 (also at Talladega) for an actual qualifying lap.
Currently Atlanta Motor speedway is the fastest track (no restricter plate used), at nearly 195 average. Top speed on this track is over 200. The COT being slightly slower than the older cars (track record is 197 mph)

The trucks are slower.. Qualifying speeds at Atlanta are in the mid 170's

For reference. The current closed course speed record is held by Gil de Ferran in a CART spec indy car at an AVERAGE of 241 mph.. hitting straightway speeds in excess of 250. This was in 2000.

Doug, Texas is the fastest track. Atlanta is 2nd.
1. Texas Motor Speedway - 196.235 MPH
Texas Motor Speedway was repaved during the 2006 season providing an entirely different racing surface for the drivers when they returned during The Chase for the Cup. Brian Vickers took advantage of the smooth surface and posted a 196.235 MPH lap to take the pole. This vaulted Texas into first place as the fastest race track on the modern NEXTEL Cup schedule.
2. Atlanta Motor Speedway - 194.690 MPH
Until 2006 Atlanta Motor Speedway had held the title of NASCAR's fastest speedway since it was reconfigured during the 1997 season. However it must now settle for second on the list since the quickest qualifying lap posted here since 2000 is Ryan Newman's 194.690 MPH lap. Newman has held this track record since 2005.
