Blackwalls refers to the Basic Wheel (BW) used by Hot Wheels after they transitioned out of the Redline wheel ending in 1977.  The Blackwall era ranged from 1978 through the late 1980's, but the wheel was still popular through the late 1990's.  So for my purposes, I'm classifying any fast BW car from 1977 through 1997 in my Blackwall group.  This would NOT include the Gold Hot Ones cars, which are a category by itself.

Racing a Basic Wheel car vs a Redline car was generally no contest.  The more effective axle and wheels of the Redlines resulted in less friction and more speed than the newer black tire models.  But with graphite, many of the Blackwalls come to life and there are a surprising number of fast models.
​Some racing details:
  • I race on a two-lane, 27 foot Magic Derby track (equivalent to about one-third of a mile).  The Derby track is 22% wider than a typical Hot Wheels orange track, allowing me to race more car sizes/scales.  
  • I've applied graphite to the cars, which really brings out the speed potential for diecast.  I'll go into more detail on that in the future.  Some cars only improve slightly, but others improve significantly when dry lubes applied.  
  • The times listed are the average of the best two times out of six races.
  • 5-star performers are the most elite and there are only 76 of them out of all the cars tested as of January, 2023.  4-star performers is the next best tier and there are less than 165 of them.

Top 25 Fastest Blackwalls

Results summary:
  • My fastest Blackwalls are largely the heavier castings.  Funny cars, buses, vans, trucks, etc.. In fact, the average weight of the Top 25 is 64 grams.  As a point of reference, a current Hot Wheels mainline cars average only 36 grams. 
  • The Baja Breaker and Probe Funny Car were close to being 5-star cars, finishing just above 2.500.  A non-Blackwall version of the Probe Funny Car is the #2 overall car.  
  • Some castings went on to speed glory as Hot Ones (Flat Out 442 and Mirada Stocker) or as future mainlines (Race Bait 308 and BMW M1).
  • Included in the top 25 is the Peterbilt Tank Truck, which comes in over the weight range of "Heavyweight".  After the famous Volkswagon Drag Bus (at 116 grams), this is the heaviest Hot Wheels (plastic wheel) casting that I've come across at nearly 104 grams.​
