Buggies are lighter so therefore can accelerate, decelerate and change direction faster, making them nimbler.
Truggies obviously have wider track, longer arms, more suspension travel and larger wheels and tyres, with more rubber in contact with the ground. This makes them easier to drive and more consistent.
As Truggy designs have improved over the years, they have got lighter, lower CoG, drive much like buggies but with greater stability.
I really enjoy looking through the lap times for each class. For years, nitro Truggy had the fastest lap times. As E Truggy electronics and batteries have got better/lighter, now we see things change.
Here are some hot laps (race times) at DNC 2024.
Elliot Boots Nitro Buggy: 44.512
Juan Carlos Canas E Buggy: 44.351
Ryan Maifield Nitro Buggy: 45.005
Ryan Maifield E Truggy: 42.313
Ryan Lutz E Truggy: 42.335
Ryan Maifield Nitro Truggy: 43.007
Interesting to note that a Nitro Truggy (.21 powered) is lapping faster than the race winning E Buggy.
The fastest E Truggy is consistently lapping 2-3 seconds faster than electric or nitro buggies. How things have changed.
