Two of the trucks are built by Scania, a P280 and a P250, while the third one is a Volvo model. The Volvo is normally a concrete pumping unit, and it has a 5.0-liter engine to work with. We don't get to see any performance figures, but we learn that the weight is about 26,455 lbs (12,000 kg). That should give it an advantage over the Scania, which is rated at 39,683 lbs (18,000 kg).
The Scania P280 has got a larger 9.0-liter engine, that is capable of 280 horsepower. The P250, a garbage truck, is not far off, with a similar setup, but with less horsepower, as you'd expect from its name. While I've never seen three trucks lined up for a quarter-mile run before, I do remember a certain quote about racing. And that goes along the lines of "auto racing began five minutes after the second car was built".
The race is so slow, that the drivers even have time to talk to each other. As the P250 driver decided to slow down halfway through the race, they decide on having a rerun. The Volvo is off to a better start this time, as it decides to start earlier than normal, and it crosses the quarter-mile line in second place, behind the P250. And nothing changes over the next quarter-mile, as the garbage truck claims the win.
Given how things have unfolded so far, they decide to forego the first two runs and do it again. At this point I wasn't interested in who was going to win anymore, I just wanted to see exactly how much it took the winner to finish the run. To save you some time, I'm just going to give you the figures. The Volvo was the fastest down the quarter-mile, with a time of 29.8 seconds. It was also the fastest down the half-mile, with a time of 46.7 seconds.
