– These days it's more common to find people building high performance, high powered turbocharged engines, so high revving naturally aspirated V8s are becoming more and more rare However Georg Plasa's E36 BMW hill climb car behind me, is probably one of the most recognisable in the European hill climb championship and I know I've personally lost hours watching or more specifically listening to this thing on YouTube videos

The engine in the car is a 34 litre Judd V8 that is actually originally designed for LMP2 Le Mans endurance racing Now in this guise it produces around about 560 horsepower at 10200 RPM It revs all the way to 10750 where it'll hit the soft cut and the full hard cut rev limiter is at an insane 11200 RPM And that high RPM is really what gives this car the distinctive sound, sounding much like a Formula 1 car going up the European hill climbs

Now these days, 560 horespower really isn't a huge amount and some of the cars that this car has competed against and beaten will be turbocharged engines producing upwards of 700 or 800 horsepower Of course power isn't everything and it all comes down to power and weight And when this car was originally developed by Georg, the design was around keeping the weight to the absolute minimum In this case, the car weighs only 895kg And for anyone who has tried to pull weight out of a road going car, this is no mean feat

Particularly when the car still has a full chassis As well as a multi point roll cage to keep the driver safe As well as the 560 horsepower and 895kg, another thing working in this car's favour is the downforce or the aerodynamic package Now this really looks like something pulled straight out of the DTM series There is a lot of work that has gone into producing an aerodynamic package on the car to produce as much downforce as possible and these cars in hill climb format will run up to about 211 mile an hour depending on the specific gearing that is used

That gearing will be changed depending on the specific hill climb the car is competing in Backing up the engine is a Hewland six speed transmission Now when the car was first built, this was a relatively run of the mill H pattern dog engagement gearbox, there wasn't a lot of electronic trickery or intervention used for the gear shifting As the car was developed, it was first of all switched across to sequential gear shifting and then finally in the guise behind me, the car is now paddle shifted This means that the driver can stay at full throttle during the upshift and the MoTeC M800 ECU will use an ignition cut to allow the dogs to disengage in the gearbox and the next gear to be engaged

On the downshift, despite the fact that this car does use a cable throttle, a little dated by today's standards but obviously the norm back when this car was developed, a autoblip for the downshift is able to be introduced by the ECU, meaning that once the car leaves the start line, the driver doesn't need to use the clutch Now talking about that MoTeC M800 ECU, of course as we've just discussed, that's in charge of the gearshift control as well as that Judd V8 engine However there are some other functions that the team are using to give themselves as much advantage as possible In particular an advanced launch control strategy and traction control are both employed through that MoTeC M800 ECU The other driver aid that is relied on heavily is the Continental ABS system

And this is adjustable by the driver to suit the conditions that the car is competing in This may allow the driver to use more or ABS intervention depending on whether the road or track is dry or potentially wet with low traction Backing up the MoTeC M800 ECU is a Cosworth driver display which also acts as a central logging hub And with the competitive nature of the European hill climb championship, this is essential for the data engineer to be able to download data after a run up a specific event's hill climb and look at ways to improve both the engine performance, the chassis performance, as well as potentially any areas where the driver could improve and hold more speed While the E36 chassis is definitely getting a little dated by today's standards, with 560 horsepower and only 895 kgs plus such a well sorted chassis in general, this car is still able to hold its own

And just a few weeks ago in testing for the 2019 Goodwood Festival of Speed, the car managed to set a new course record at a local hill climb during practice Personally, I'm just glad that someone's still racing a high revving, naturally aspirated V8 among that sea of turbocharged engines If you liked that video make sure you give it a thumbs up and if you're not already a subscriber, make sure you're subscribed We release a new video every week And if you like free stuff,  we've got a great deal for you
