My favourite bit too!

I would like to point out that modern F1 engines are more efficient than it is stated in the video. If we consider that within the rules, an F1 car can carry a maximum of 105kg of fuel, that is around 145L (105/0.721=145.6). A normal GP is a distance of around 305Km, so (100*145)/305= 47.7 L/100Km which translates to 5.9 miles/gallon (UK). And that is if we take that in every race they start with the maximum amount of the fuel they can, which is not correct as many teams start with much less of it due to wanting to be lighter. With an over-estimate of lets say 80kg of fuel onboard, fuel economy raises to 36.4 L/100Km or 7.76 miles/gallon (UK).

​@@michalisevripidou6461 You're right, but an F1 car is still not 5500 kg ... and let's not forget about the amount of drag that giant cabin produces at higher speeds, I was surprised with the average 2 miles/gallon... I was guessing 2 gallons/mile :)))

too bad that despite almost every hgv starts at 400+ hp they are weak as fuck even when empty trailer attached :D

Yes it is unreal volvo has a truck with 2300 hp and it does 0-100 kph in 4.6 sec so i think what they meant was 100kph not mph

Try the A414 shortcut to the M1 if you really want some fun!

Rally does the same

Farhan Ahmad Tajuddin look up figure 8 racing, that’s crazy.

Why don't you like 5th gear?

@@TheDennys21 No culture.

16 speed is just 4 low gears, 4 high gears and a gearsplitter (overdrive) for every gear... so without a trailer he can keep the splitter active and start in 2nd gear, move to 4th gear move to 6th gear and move to 8th gear with a splitter.. because he doesnt have a trailer to pull he can skip gears.. its easier to do, then to explain it from my experience

What is not being shown is the fact these transmissions appear to be synchronous meshed boxes .north American class 8 units have up to 18 to 22 gears and are all NON synchronous

@@thomasburke7995 as the guy with the black truck saids.. its basicly a factory engine and gearbox with the boost put up higher... witch can be done.. and a diffrent gear ratio in the rear diff to let the truck do 160 km/h without pumping out 6 pistons at 2500+ rpm... as that is where the factory revlimit is

@@thomasburke7995 All due to stubbornness and stupidity. There's no need for non-syncromesh manual gearboxes in heavy trucks anymore. It would be better for both comfort and fuel economy to use an automated/robotic gearbox like the Volvo I-shift.

There basically only using the top gears whilst racing

only in the summer, and in warm climate. In scandinavia it would be the cause of many deaths during the winters, and over the mountains during the spring and late autumn.

@@bjrn-steinarhanssen2102 why? That probably is software activated to cool only when needed

Normal trucks don't have brakes near as good as this ones. The problem is not the cooling solution, which in this case is needed because of the extreme temperatures they reach in during races. If a normal truck has a brake failure, it's because it doesn't have good brakes at all.

@@shafoz i dont believe thats true at all, hete in Brazil its common for trucks to lose brakes while going downhill

@@ShakamuraGames Then they don't have proper brakes What you don't understand is that during racing brakes reach 900 degreess that's why they use this system

IMO 0-60 MPH...Chiron makes 0-100MPH in 4,4s!

It's obvious there, 100mph.

@@brax1108 You don't compare the Chiron with a racing truck, they are as different as chalk and cheese.

@@FAT8893 The point is that there is clearly a mistake in the title - 5,5 ton truck with 1100 horsepower can't do 0-100 MPH at 5 sec. Must be a typo.

Rather 0-100 km/h or 0-60 mph. It will match power to weight ratio.

Wrong video mate

Lol, you must be new here. Also, Top Gear has been around since 1977 and she used to work for Top Gear.

@@farishanafiah8461 yeah...but it is fifth gear, not top gear, so it is a cheap copy...
