How fast are Tractor units, i.e truck without the trailer ?
Discussion
The Volvo truck thread reminded me that a few years back, a truck obsessed acquaintance proudly told me how his dads truck would out accelerate my mk1 Golf Gti, never though about that until now, I just kind of ignored him as be was a bit of a Billy Bulls
t merchant, thinking about it, if something can tow 20 odd tonnes it is pretty powerful so with that load removed it must have plenty of power in reserve but out accelerate a hot hatch, I wouldn't have thought so, don't they need quite a few gear changes, would be interested to hear how quick they actually are.

Pull away in 5th Low block change to 7th low and then into 8th High, I was more than able to give my mates old VTR a run for its money once rolling to 56,
Most new trucks are auto and can't be abused in the above manner the same

back in the "good ol" days, a manual tractor unit was amazinngly quick out of the blocks
and like martin says, start in the right gear, get a smooth change from low, to, high range you'd surprise many a car.
i also here that unit only, roundabout drifts were more than possible. apparently.

The DAF was certainly better, read easier, to abuse than my manual Scanias I had more recently
The dafs were always good for holding a drift, has to be manual whatever it is though.. Favorite Scania youtube drift
Going on averages a solo unit is about 8 tonne with 500bhp, so 60bhpt.. about the same as a 1.6 fiesta?

A tractor unit will out drag a typical car off the lights, with an auto box its pretty easy. A Scania R730 for instance has 2500lb/ft of torque.
I remember being behind a solo unit in a transit van a few years ago, when the lights changed i went to pass it on a clear road only to be shown a clean set of heels

Gives you an idea of the torque, doesn't just happen in bond films

I disagree here with the auto box, they are not programmed correctly to enable a quick sprint from the lights like you can in a manual truck. They choose too low a gear to start with and don't change in big enough blocks.

A unit will easily outdrag a transit van, I have done this several times in situations like you describe.
Pretty good.. Specially with Volvo IShift.
With an empty trailer it'll use 5th or 6th to start in, then to 9th to 11th then 12th
It'll pull a high gear from such low speeds it doesn't really need lots of changed.
MK1 Golf GTI vs an average 450hp unit... In gear then it's highly possible the truck would pull away. But not for long.

I once took an old scania 113 450 unit from the yard to the service workshop ,this scania had been fitted with an uprated pump (in the time prior to re-maps or chips) also prior to speed limiters ,this thing was huge fun !Plenty of slides loads of black smoke from the stack pipes,silly speeds !
It's the monster torque that does the damage and great fun when driving solo. Love it when I'm told to go solo thru the tunnel to the docks. Surprisingly gives good MPG. It's no problem getting 17 MPG driving solo.
Also love the feel of how the torque pulls going thru the tunnel fully freighted and hearing that big old turbo whistling.
Reminds me - today a scania with sidepipes overtook me (seems to be a daily occurence), the noise and the little effort of those torquey V8's is gourgeous

They can be surprisingly quick.
If moving solo across town it's known to get some cars up your harris and occasionally you might boot it off the lights and roundabout and the car behind will be struggling to stick with you.
It's only cars with the bigger engines that can keep up tbh.
Seen a lot of solo units nail cars at a set of lights,always makes me chuckle.

- Dependant on trucks bhp.
Here is the story from the day one took my by surprise, I was driving a Daihatsu Sportrak when this happened
