5 Things You Should Never Do In A Rear-Wheel Drive Car
1. Don't mash the throttle while turning
This is especially common for people who’ve come out of front-wheel drive cars and suddenly find themselves with a lot of power and no idea about how it deploys differently. In FWD cars, if you give it too much throttle you’ll understeer - fix this by lifting off the throttle and you should pull back onto line without much fuss.
If you’ve got any sort of lock on, you’re pushing the car’s weight to the outside of the tyres. If you then mash the right pedal the amount of grip available will be lower than normal, and you’re going to lose traction - in a RWD car, that means the back end is gong on an adventure. That’s when you need to start feathering the throttle to bring the car back under control, and that’s not something most people do instinctively. What most people do do is snap their foot off the throttle and then brake, which is an excellent way to lose control. Which brings us nicely to…
2. When breaking traction, don't brake or lift sharply off the throttle
Remember when we talked about ways to initiate a drift? Most of those techniques involved un-gripping your rear tyres and shifting weight; here, again, we’re talking about working with the weight of the car to keep it under control.
If you’re pulling a burnout or have found yourself oversteering, lifting sharply off the throttle might be your natural reaction, but it’ll lift the weight off the rears and provide even less grip than you already had. If you brake you’re just exacerbating this issue, and you’ll find yourself spinning out before you even know what’s happened.
Instead, you should avoid hitting the brakes until you’re straight, instead easing off the throttle to minimise the effects of the weight transfer, and bringing the wheels back to grip in a manageable way.
This is kind of a given for any car you care about, but it can have particularly disastrous consequences in a rear-wheel drive car. The idea of heel-and-toe downshifts is to match the engine speed to the wheel speed, which in turn keeps the car stable by removing any jolts from the transmission.
If you downshift too early, the rear wheels will lock up, which has the same effect as yanking the handbrake. Want a visual representation of that? Our very own CTzen Chris DedicationBlog accidentally shifted to 2nd at 90mph, and caught the whole thing on video. Heel-and-toe probably wouldn’t have saved him here, but use this as an example of what can happen, even to experienced drivers like Chris.
4. Don't pull the handbrake without depressing the clutch
This one’s extremely important for all-wheel drive cars, but it certainly ain’t a healthy thing to do in rear-wheel drive cars either. It’s quite logical really, but if it’s never crossed your mind you could unwittingly be putting a lot of strain on the transmission and engine by not disengaging the clutch when you pull the handbrake.
Obviously, the handbrake’s job is to slow the rear wheels, so if you don’t depress the clutch then the transmission and engine will be under heavy load trying to fight the handbrake to turn the wheels. You probably won’t break anything unless you leave the handbrake on for extended periods, but it’s not good for your car.
5. Don't go out in the snow without suitable tyres
Again, this should be a general rule no matter which wheels your car sends power to, but you’re most likely to be stranded in rear-wheel drive. If you don’t fit winter tyres to your four-wheel drive vehicle, at least you have the power evenly distributed to scrabble for whatever grip is available, and with front-wheel drive, front-engined cars the weight tends to be over the front wheels, aiding grip.
Rear-wheel drive cars typically have less weight over the driven wheels, meaning you’ll just end up doing pretty pirouettes without going anywhere near where you actually want to be going.

dont mash the throttle if you’re a rwd virgin…after a short while you get used to it, I happened to have my first rwd vehicule at the beginning of winter, first thing I did (after putting proper nokian winter shoes) was to find an empty parking lot and learn the cars reaction….I think it is actually good I had it at my beginning of my mechanics career, we drive all sorts of cars so we should be ready for any drive-type
My car has a friendly reminder to not downshift into 2nd from 5th… grinding cogs and the smell of burning clutch!
Good read. Hadn’t actually thought about the handbrake/clutch issue before.
Guys, have you ever been interested in cars?! I mean, how can you not know these things even if you don’t have driving license yet? My first car was FWD and my second car is RWD underpowered e36 and I knew all the things in this post even before I get …
… My 320i. The closest thing to my mind in rwd cars is that the handbrake stops the driving wheels, so if don’t press the clutch and pull the handbrake the engine will stop!
The last thing i want to say is that if you’ve been driving fwd and get more p
Powerfull rwd car you should first get to know your car’s behave in different situations, and then try to be the next keiichi tsuchiya. In my opinion a men who don’t know how to heel and toe doesn’t have to drive rwd with manual.
Greetings from Bulgaria!
I dont know how to heel and toe. Im still working on perfecting Rev matching on downshifts for overtaking.
I’ll add one for rwd vans hills and ice and nothing in the back is going to end badly

Or if you want to have some fun do all of the above (except pulling on the handbrake)!
basically do all this to initiate a drift, with your reasonably powered rwd car, all of the above wouldn’t be an issue with a miata btw, open diff and a whoopin 75 rwhp
The aggressive downshift can still be problematic though
