Can-Am Spyder 2010 Technology - How it works

4-27-2010

Semi automatic gearbox
The SE5 option means that servo devices operate the clutch and actually change the gears for you when you push a toggle switch on the left grip. The electronics are smart enough to release the clutch properly and to downshift to first when you stop, and the actual mechanical parts of the clutch and tranny remain the same as for the manual models.

Controlled behaviour – that’s for sure
The cumulative effect of the VSS components turn the Spyder into a safe, usable vehicle, one that will help the driver regain control in an emergency, but also put the kybosh on more aggressive driving. And with good reason, as the Spyder’s 2-1 configuration produces complex behaviours when changing direction, and becomes dangerous as the driver closes in on the adhesion limits.

For example, a look at BRP videos shows that the Spyder leans over considerably; to the point of lifting the inside wheel off the ground and leading too easily to a tip over if uncorrected. The Spyder depends on the front tires for a large part of the suspension springing, as the 13 to 17 psi recommendation shows. The outside front tire leans over and deflects, almost as if it goes down on one knee, thereby making it easier for the inside wheel to get off the ground and the whole thing to roll over.

The Stability Control function cut power and applies the brake to the overloaded wheel, to slow things down and pull the Spyder back in line, reducing the turning motion and settling the machine back down.

BRP are correct in using these safety features, but that did not prevent independent companies and individuals from to build bypasses for these systems in order to go faster, thereby putting themselves on a knife edge when pushing harder.

Cornering a little harder – A new fitness program
A Spyder driver must hang on to the bar when cornering as there is no inside lean to ease the task, a manoeuvre that is complicated by the fact that the machine leans to the outside, which pushes seat, pedals and bar away from the driver who leans to the inside.

This translates into energetic cornering becoming a real exercise, just like on a snow mobile or Quad for those who like that sort of thing – and a good way to stay fit.

Less active riders will also have their fun, by respecting the laws of physics as they concern inertia, and drive around more slowly. Good enough, but I do not like what can happen in an emergency where the driver or passenger may be caught unprepared.

So where is the Spyder going?
The Spyder reminds me of the first Porsche 911 from 1964, a car with flawed handling from the git-go, and that Porsche gradually turned into the sweet handling, high performance and safe cars we know today, with the help of electronic and 40 years of development.

Luckily for BRP, the electronics are here now, and they make the Spyder safer for everyone who drives one – right now.
