How to Autocross Your BMW

It might not be the fastest race in the world, but autocross is one of the best ways to get your foot in the door — so to speak — in the world of racing. Autocross is an amateur race where all you need to enter is a driver’s license, a vehicle and a helmet. If you’re interested in auto crossing your BMW, here are all the tips and tricks you need to know to get started.

First, Pick up a Helmet

Bicycle helmets won’t cut it for an autocross race. Your helmet has to be DOT rated, but only class M for motorcycles or class SA for special applications are allowed on the track. You can take the visor off if it interferes with your vision, but you have to keep your head covered. If you don’t have your own helmet, show up early — most tracks offer a limited number of helmets for rent, but they’re first come first served, so you need to show up early to make sure you can get your hands on one.

Pick the Right Class

There’s a variety of different classes of autocross races, so it’s important to make sure you pick the right class. Street category requires street tires and limits the number of bolt-on modifications allowed. Street Touring still requires street tires but allows more bolt-ons. Street Prepared allows racing tires and bolt-ons, while Street Modified allows more internal engine modifications. Prepared and Modified categories have higher allowances for mods.

There are also classes for classic American muscle cars, vintage cars and karts.

Walk the Track

Autocross isn’t just a race — it’s an automotive obstacle course. The nice thing about autocross races is that you don’t have to have a dedicated track for a race. As long as you’ve got enough space, you can set up an autocross track in a parking lot, an empty field or anywhere that’s flat and open — as long as you have permission, of course. Grab some cones or some easily removable parking lot paint, and you’re good to go!

Once you’ve arrived, take a few minutes to walk the track and figure out where the curves and tricks are to give you an advantage once you hit that starting line. If you need some help, ask — chances are, you’ll make a new friend in the process, and you may even learn something that gives you an edge.

Get Inspected

Before you can take the track, you’ll need to get your car inspected. Make it easier for your inspector — open the hood and take all loose items out of the car. You’ll also need to take the driver’s side floor mat for safety reasons. The inspector will check things like the lug nuts, wheel bearings, suspension and battery, as well as the seatbelts or harnesses, brakes and accelerator. The goal is to make sure your car is safe and ready to race, whether you’re racing in the street class or one of the modified ones.

Once the inspection is complete and you get your numbers, it’s time to get into the lineup and race!

If you want to try your hand at racing but don’t have the skills to get into a professional racing circuit, autocross is a great place to start. It’s competitive, but in a casual sort of way, and if you’ve got a helmet, a driver’s license and a car, you’ve got everything you need to enter. Make sure your car is in good shape, learn your track and whatever you do, don’t forget your helmet!

A BMW Buffet

How often are there several fast BMWs lined up for your pleasure on a racetrack? Not often I must say, so how could I say no? There are far worse problems in the world.

Last month I was sent to the smoldering La Quinta, a small resort city near Palm Springs, in the midst of July. For those that are unfamiliar with the region, I can sum it up in two words: it’s hot. And I mean hot; Everyday was upwards of 110 degrees Fahrenheit. This was all part of a training program to be a BMW Genius. A Genius is a new(ish) role in the BMW retail world with goals to bring the cars and BMW experience closer to the customer. While most of the week was spent in a ice-cold conference room of a hotel (who thought I would have been cold this week?), one afternoon we were shepherded to the Thermal Club. For those unfamiliar, the Thermal Club is a private racetrack nearby that also plays home to the BMW Performance Center. Here, BMW enthusiasts and owners sample cars in a fast, controlled environment, whilst perfecting their driving skills. We would be given the chance to see just how well modern BMWs excel on the track and to provide us with some fun.

The victims? M235i’s, M6, M4, X5M, and a 340i.

My first rendezvous was with a soaked, concrete skidpad and an M235i. And it was downright marvelous. I had never driven on a skidpad, let alone one with sprinklers, but the natural balance of the small Bimmer turned it into an arcade. In the halfway-traction control setting ‘sport +,’ the M235i couldn’t stop spinning the rear tires even up to 3rd gear at 30 MPH (8 speed ZF auto), such was the slickness of the surface. But use the throttle to steer and it became just epic fun, holding long slides circle after circle. Sure, it required lots of steering input, not in terms of angle, but constantly changing from turn-in and countersteering. The 320 horses made by the Gillette-smooth 6 were more than plenty, and anything more would’ve surely resulted in some serious spins. The strangled steering feel also didn’t make for any issues here. Great seats too help prevent you from flailing around the cabin when sideways as well.

Next was a permanent autocross circuit, not even a half mile in length to sample a few of the M’s (and half-M’s). The M6 Compeition was first and starting off slowly to get a feel for the car and circuit, I can’t go on enough about how nice of the car the big 6 is. The cabin is such a lovely place to be, though the buttons and controls that are shared with lesser BMWs slightly cheapen the feel, the overall aroma of it all put the thought into the back of your mind. The demonic sounding V8 also is a nice touch. But soon it becomes clear that, even with the competition package, the M6 is not at home here. The power is incredible and the brakes do a remarkable job hauling the yacht back down, but the weight shows itself in corner transitions through the quick couple esses for us to play with. I’m sure on the large, real Thermal Club it would be sublime, being able to use the wider tarmac of an actual race track, but the thin confines of the autocross don’t encourage the all-out attack that the next car begs for.

Which brings us to the M4. And no, it’s not even the new-for-2016 Competition, just a standard M4. Immediately it’s such a more focused car here. Blasting down the short straightaway it doesn’t even feel any slower than the M6, which was barely clearing it’s breath by 70 MPH. Everything else, the braking, the turn-in with ferocious front bite, and the rotation the Active M diff provides is sublime. I’m not terribly fond of the M4 as a road car, but here in a closed and controlled environment, it really makes its case known. I found it best to turn in with a trailing throttle to help keep the back end rotating slightly to help hit each apex and propel down to the next braking zone. The standard steel brakes seize forward momentum rapidly, with no fade encountered either. The S55 up front never needed full revs, being more than happy to live right in the midrange at 4-5k. The DCT also gave snappy changes up and down on command. Track driving is what the M4 yearns for. If you have one and are yet to unleash it on a track, please do so before the years out.

And then came the oddball of the group: the X5M. Now, I’m still not quite sure why this ‘thing’ exists. But when talking about defying physics, it’s the first-prize at the science fair. Quite how it’s able to go around corners so quickly is beyond me. Braking points are much earlier too than the M4, with the car leaning on its outside tires as the 4WD system figures out how to help you around the bend. Sure, it’s somewhat satisfying charging down sports cars in a 2.5 ton SUV, but the experience is rather muted, more interesting than fun. If you can afford the price of one, why not buy a diesel X5 and an M4 for this sort of work? Though if you want one to do it all, then it’s perfect for that niche. It is blazingly fast, and impressive, but it’s no sports car.

The last on this section was an M235i again, but now in a totally new environment. Here, compared to the others, it shows it’s lack of real M-credentials. Not to say it wasn’t fun, in fact it was the most playful of the bunch from its lack of focus. Power is mundane after the M’s, but it’s still plenty for this tight track. Under braking and cornering there is much less composure and more body roll, going into understeer when pushed too hard, but still maintains great control and adjustability to play with the chassis. While not as fast in any direction, it becomes more involving as it requires more work, and I rather like that. Conclusions from this section came to be that while the M4 was the best on the autocross, the M235i was a close second for its irreverent brand of fun.

And lastly we moved again to another autocross, being longer and more technical, and with the least dynamically capable car here: the 340i. The new 340i replaces the 335i with a host of small suspension tweaks and a new power plant compared the now defunct 335i. It also makes 20 more BHP. The overall feel of the car is very akin to the M235i but with a chassis that’s prone to even more roll and a differential that can’t quite put all the power down through corners. Having driven the 340i on the road it’s a fantastic piece of kit for daily driving, but it’s less at home here. However, like the M235i, the waywardness of the chassis made for a highly involving experience. Though it showed understeer in the tight hairpin of the circuit, fighting that force and driving the car out using the power made for a satisfying time. In the two higher speed sweepers it was oversteer that had to be fought, and again it was fun despite the lack of balance. If the car were perfect, it wouldn’t be a challenge.

As the engines, tires, and brakes cooled, I reflected on an incredible experience at the BMW Performance Center. Driving a BMW on the road is one thing, but having the time on a track in one is leagues better than one could hope for. It wasn’t my first track day in my life, or my first at Thermal, but the adrenaline never gets old. The three instructors on hand for the day, Dave McMillan, Emile Bouret, and Adam Seaman, were astounding as well, giving great guidance and keeping us in check safety wise. After we were done, they took us out for drift laps in M3s, showing us how capable the cars are in the right hands. Mission accomplished guys. If you’re considering one of the programs at Thermal I highly encourage giving it a go, for the great facilities and instructors, let alone the cars. Now to browse parts catalogs to see about making my old ZHP ready for an autocross…

We then walked on to the apron where all the car were parked and Matt took us to an F10 M5. He said it was only right that us M5 owners should go on track in an M5. Ladies and Gentlemen…… the next 10 or so minutes of my life were one of the most memorable, kid in a candy store smile inducing, heart pumping minutes ever!

The BMW Performance Driving Center in Spartenburg, South Carolina is the home for some of the most fun driving you can have. Not only do they have a state of the art facility, but they also have cars that are prepped and ready for you to drive. One member decided to drop by on his cross country road trip. Not knowing what he would find given how he was snubbed on the phone when he called BMW’s corporate offices, he was taking a risk. He was sure glad he did.

After chatting it up with reception people, he greeted by some friendly faces and one of the best instructors … Matt Mullins. Mike Mullins a fellow E39 M5 aficionado took the time to talk and trade stories with a grateful member before giving him a tour of the facility and ultimately taking him around the track for a sight seeing lap of one of the best playgrounds in the country. The car of choice was a brand new M5.
