Diesel Fury: The Black Smoke 300td Wagon

This is one car I have been hanging on to for a while now. Shot back at Gatebil in July, very late at night as the midnight sun approached, it remains one of the most memorable drift cars from the event. Why? Well how can I put it; let’s just say that a lot of the time cars aren’t necessarily judged on sheer performance, looks or the actual budget that was necessary to create them. For a lot of the cars that participated at that insane summer event at Rudskogen, character goes a very long way. At this grassroots level it’s the enthusiasm of the owners, car builders and teams that help us form an opinion on a particular car. The guys at Black Smoke Racing were some of the most enthusiastic guys I met there and it really shows on this extremely fresh, unique and straight out crazy car they have built.

Their 1981 W123 Mercedes Benz 300TD over the last couple of years has become one of the most recognized drift cars in Scandinavia and the Baltic region. Built in Finland…

…and driven by Teemu Peltola, what actually makes this car quite a bit different from anything we have seen before, isn’t so much the fact that it’s a station wagon, or a Mercedes Benz for that matter, but – as the team’s name suggests – that it’s diesel powered.

As this image captured by Rod perfectly shows, this beast churns out just as much black soot as it does creamy white smoke from its tires.

It has developed quite the following too, fans of drifting attracted by its unconventional approach and of course Teemu’s aggressive and “pedal to the metal” driving style.

But for me it was the car itself that grabbed my attention. After seeing it in countless videos on You Tube and then there, at Gatebil, in front of my eyes I was very curious to check it out in detail.

As Patrik Wargh of Black Smoke told me, the day before the event the 300TD was involved in a pretty big accident at a Monster Energy event Teemu and his team attended in Gothenburg. The car suffered massive damage to the passenger side wheel/suspension and they spent most of the night repairing it so it could still be entered at Gatebil. They got it mended, but not perfectly, which is why the car sits at a bit of an angle, as you can see in the opening shot. But I was reassured it was no big deal, as it was very much drivable and more important driftable!!

Looks wise this Benz wagon has an interesting feel to it; I’m not sure if it’s to do with the wood-grain vinyl that covers the roof, sides…

…and hood, but if I had to describe it I’d probably have to say it has some hearse-like “qualities” to it, hearse meets the Addams Family! There are a lot of interesting touches that are observable pretty much everywhere, like the opening cut out so that the hood can clear the rather larger turbo charger.

But things, as you can imagine, get a lot more interesting once you lift that big hood and grille section…

…revealing what can only be described as a very industrial looking power plant.

The 1998-model OM606 3L straight-6 has now covered over 400,000 km (just under 250,000 miles) so you could say it’s well run in. At its heart are a set of Arrow H-section connecting rods as well as a set of slightly modified stock pistons to help make for a close to bullet-proof bottom end.

And that is a good thing because the Holset HX52 top mount turbine, sitting atop of a custom fabricated manifold, supplies a massive 3 bar of boost…

…sometimes, depending on the track and situation, up to a max of 3.5 bar. Boost control is taken care of by an external wastegate, which helps give the Black Smoke Benz a sound all its own.

The radiator, as we will see further down, has been repositioned in the rear of the car, freeing up much needed space and allowing the intercooler and oil coolers to get a steady supply of cooling air. Nothing too surprising thus far…

…except there is more. In the pursuit of zero lag and optimal throttle and torque response the team have taken a series of other steps, which includes fitting an Eaton MP90 supercharger, directly feeding the turbo.

The Holset takes over once it is able to make full use of the exhaust gases, and the supercharger is simply gated to atmosphere via a valve in the system. If that wasn’t enough…

…they have even thrown in a touch of nitrous oxide to help spice it up…

…fitting a single fogger on the intake side. The switch-activated system gives an immediate 100 HP boost in power, on top of the already impressive 600 HP and 664 lb/ft of torque the “twin-charged” motor develops. I guess the nitrous would make it “triple charged!”

Here is a look at the custom intake manifold that was made up to boost flow to the twin-cam head. Each of the blue lines you see above have a different job for things like water injection, wastegate control, boost read out and diesel pump control which has to pump in a lot more diesel as boost increases.

This impressively modified engine is mated to a 5-speed automatic transmission from an E55 AMG, which has been modified with a custom logic box to allow Teemu to manually select the gear. Of course being an auto with torque converter the gears can be shifted while keeping the accelerator pinned to the floor.

The more time you spend looking at this thing the more impressive and complex it seems to become.

Which takes us to the cooling system…

…which is located in the rather large trunk area of the car and fed by a total of four large industrial flexible pipes…

…two on each side. The actual radiator sits inside this aluminum box…

…created to get the best effect out of the channeled airflow. And in case you are wondering if enough air flow can actually be directed towards it…

…keep in mind this car spends most of its time travelling sideways so there is potentially a rather large volume of air that can be captured by those four large openings.

The team’s mascot is this big wrench, which they have named Roger, now sporting a Speedhunters sticker for added torquing power!

Suspension wise the car sits on RX8 coilovers which have been modified by BIGEM to fit the W123. And that isn’t the only JDM addition, the car also runs Toyota Aristo axles.

To get a pretty big 60-degrees of lock a combination of Volvo, Toyota and Mercedes components were used in the steering rack, helping Teemu get those extreme angles we all saw at Gatebil.

The interior is very driver-focused and functional, with everything that wasn’t needed having been stripped out to shave as much weight off the big wagon as possible. A multi-point roll-cage was fabricated, helping to stiffen up the 30+ year old shell.

Momo bucket seats followed, along with 5-point harnesses, keeping the driver and occasional passenger nice and snug not to mention safe.

It’s not often you see a boost gauge that reads up to 4 bar!

The main shifter has been retained…

…but as previously mentioned a secondary manual shifter has been added to manually select the gears in the E55 AMG transmission. Like in true sequential pattern you pull back to shift up and push forward to downshift.

Open the paper-light rear doors and the rest of the roll cage is revealed…

…as well as things like the canister of nitrous oxide and Optima battery.

As good as the car looks up close it really is in its element doing this sort of stuff!

You should check out some of the awesome videos on the Black Smoke Racing You Tube Channel to see the W123 in action. After three years of use however, the time has come to retire it, and the team is already working on its replacement, a W209 CLK. Of course it wouldn’t be a Black Smoke creation if it wasn’t diesel powered so you can expect a similar engine and transmission combo in the new car. With 400 kg less to play with the CLK is certainly going to be a lot faster and I for one are very excited to see what they will come up with!

i hate to be that guy, but near the end it says Lik4e.
Nice car though, got boost?


wow supercharge, turbo, nitrous what more?


YESSS FINALLY A FEATURE ON BSR!!!! Im a huge fan of these guys. I love diesels & I've been following these guys since the first came on the scene a couple years ago!! (Look them up on facebook to follow their season) Huge respect for these guys going out & being competitive while still being very unique in this sport!


35 shots of it parked and only 4 shots of it actually drifting?


@aqswdefrgtda Well thats not entirely Speedhunters fault. As Dino wrote we got the car pretty smashed up before the race and had a lot of things to fix in the pit so we had pretty little track time on saturday. If you want to see it drift check out the videos :)
Joni /Black Smoke Racing


@aussieANON Fixed :)


Water injection? lol


@Dusty Monkey Yep can't agree more!


@aqswdefrgtda Also please consider this is actually a "car feature," so we tend to concentrate on the car itself :)


This car is a beast! Black Smoke Racing is quite something different :D It would be interesting to see it at Formula D or D1 :P


Bent chassis or just sitting lower on one side?


Awesome feature,  I'm just curious on how the transmission is set up like that


is the frame bent from DIESEL TORQUE HUAGAH CUMMINS or from crashing/just being an old car


Rod, you missed including a closer shot of those awesome Mercedes-Benz gussets!


sorry, I mean Dino, the last two photos said Rod Chong.


Best drift car ever! Soo much impressive technology on that diesel :)


@speedhunters_dino I hate being "that guy". My OCD was tingling.


@speedhunters_dino I hate being "that guy". My OCD was tingling.


I've seen a video tinho doing this drift car. It's insane, is sensational.


the epitome of awesome!
I want to know how that transmission is hooked up, auto with manual override?


A twin-charged, sequential transmission, diesel Mercedes wagon that drifts. Now I have seen everything!


Greatest drift car ever. OM606 owns.


Diesel Powahhhh :D seen this live , gotta say it's insane :D


@Jimbowe It sure is!


@nickcontey The what sorry?


@ComJive So much torque, it bends the chassis...


@Monster Ortiz Maybe some of the Finns from Black Smoke can go into more detail on this


@JakWhite See above


@AlexanderEvensen Maybe the new car haha.  How about it guys?


@speedhunters_dino Should be this one :P Diesel power!


Black Diesel smoke plus White Tire smoke, well gotta say it gives a tons of contrast of colors while drifting.
And I LOVE Diesels. It has plenty of torque add the chugging sound at idle engine speed it is a true music to the ears like a high revving DOHC 4 cylinder gas engines.


@speedhunters_dino  The gussets for the rollcage along the inside of the A-Pillar have the Mercedes star in them :-)

Beautiful and amazing car......


There they are! thanks for letting me tag along for the shoot mr. Carbonare :)


Have you tried this site? http://www.wrenchwarehouse.com


Beautiful and amazing car......


Hey, very nice site. I came across this on Google, and I am stoked that I did. I will definitely be coming back here more often. Wish I could add to the conversation and bring a bit more to the table, but am just taking in as much info as I can at the moment. Thanks for sharing.
