The development of the all-electric Porsche Macan
For 10 years now the Macon has been a bestseller now the new all electric one is here I’ve driven the Prototype it drives like a Porsche York what goals and challenges were there during development in terms of retaining the identity of this successful model line when we develop a new model Porsche
Always focuses on performance and driving Dynamics that’s Porsche that’s our DNA exactly that coupled with efficiency and our design language was the challenge and mastering that challenge was our motivation could you give us a ballpark estimate of how many pre-production test kilometers the model will have well I
Can tell you that we’ve recently done over 3.5 million test kilometers that’s several 24-hour of Lama in a row you have to drive a long time to get that far we’re on the road worldwide we have to cover all temperature ranges so minus 30 to plus 50° which we get in Death Valley
For example we have an SUV so we want to cover the full spectrum there as well so we do gravel snow sand to get the whole picture we’re all over the world it’s essential that the car looks like a Porsche everyone has to see it the fly
Line has to be right and yet the efficiency has to be there as well and of course the drag coefficient is a key factor here that’s a very interesting point I was in the wind tunnel and the aerodynamics engineers and designers explain the vehicle and its efficiency to [Applause] me wow Thomas what area are we in here in the Wind Tunnel this is wild we are right in the center of the aerodynamics development unit at Porsche you see the big motor in front of us I’ve never been in a wind tunnel and certainly never
Been so close to this fan the dimensions are crazy this is where the wind is accelerating it’s about 70 km an hour here and it generates 300 km an hour in the measuring section but not here no not here right here the speed is significantly lower I still have loads
Of questions so let’s move on to the C And we’re now showing those who made this car Peter our designer and Andy our aerodynamics engineer hi what is the teamwork like what does the designer want what does the aerodynamics engineer want and are there any sticking points the basic design should be classic Porsche and that sometimes conflicts
With the specifications they set out for us we then have to harmonize things so that it still looks good and also functions well in any case we work on every millimeter yes this is true it was a pretty intense collaboration with the designers particularly these Corners that are so nicely accentuated here the
Aerodynamics engineer always wants to take it further especially when there are shorter overhangs and when the design wants to stay further in I think we found a great compromise here in combination with the air curtain Channel it must be said that this is still a prototype and not the car of
Course you can already see where it’s going I already feel it’s absolutely inspiring it’s still a prototype but at least you can see the things were still working on the things were still putting the finishing touches to can you give me a few specific examples that perfectly
Show this teamwork I think it also meant your needs when we said that from an aerodynamics perspective we’ll move the brake cooling from the underbody to the front but then we could compensate for that with the cooling air flaps and still create a relatively bullish front without a trade-off in terms of aerodynamics
I’m familiar with that from Motorsports where we drive with a closed underbody like in the LMP back then and that makes a huge difference how is that here in the new Macon the battery floor means we have a completely closed underbody and in this car we also achieved securing all the areas
Connected to it such as the front and rear axle housings so they are completely flush that brings us to the subject of the components that turn namely the wheels the wheels when you look at these vehicles are more more closed they have less air flow and we
Don’t need quite as much brake Cooling and this is totally new the tire side walls are optimized I have add one thing designers love big wheels and the Macan has huge Rim sizes we go up to 22 in that’s incredibly attractive this means the vehicle has large sized wheels for
This overall length in the wheelbase I’m personally very happy about that and they are fully optimized yes we still haven’t talked about the rear because there’s a lot going on here we can ultimately say that the roof line from the B pillar and on the rear was
Actually the enabler in terms of getting these low drag coefficient ranges with a vehicle of this size and in this segment can you specify a value with the maon we achieve a top CD value of 0.25 that’s a tenth better than the predecessor which means a huge step
Forward a huge jump that ultimately means 85 more kilm of range just through the aerodynamics this vehicle has very high and ambitious targets and we agreed that we could only get there by revisiting the entire roof line we’ve adapted aerodynamic elements that make the vehicle even better in different driving
Situations but we integrated them really well and integration is quite important in the sense that you get a much clearer and cleaner design Sol this design now we can see the technology under this aerodynamic Shell let’s dig into the details can you give me some outline
Data a few figures we will have over 450 KW of power in the vehicle over 1,000 Newton met of torque and we’re well under 4 seconds from 0 to 100 that felt extremely fast and I have to say reproducible as well that’s our standard feeling that thrust not one time but of
Course over and over again and what we promised in the past we are promising with the electric cars as well can you show us where this dynamism comes from the key is packaging and weight distribution one thing is key of course the battery in the center with an
Extremely low center of gravity helps but when you go back here you can see how we’ve moved the drive further back this enabled us to create the space here for the rear axle steering we have an adjustable 5° angle this gives us an outstanding turning Circle and great
Driving Dynamics I don’t have to tell you what rear axle steering does for the Dynamics and Visually you can also see that we have a very powerful electric motor or a fully variable distribution of the power to top things off we have a height adjustable air suspension with a
Two valve damper which easily spans the full range between sportiness and comfort how did you resolve the question of getting the characteristic Porsche Dynamics and performance as well as range the first thing you need is power to get enough power you need a very powerful electric motor but also the
Right back battery we integrated a 100 KW hour battery in the car of which we can use 95% and then you have the element of recuperation we can recuperate up to 240 KW using the brakes in other words you only rarely need the friction break many will be interested in
Charging that is as fast as possible in which ideally functions flawlessly anywhere can you give us some numbers there as wide as possible charging window was important to us we can charge with 270 KW and that over a very wide range but I think it’s quite impressive
That we can recharge for 100 km in about 4 minutes I think those are really impressive values do you test how charging Works in different countries that’s very important we have different charging standards so we go all over the place in our main markets to try them
Out and to use charging as well because charging an electric vehicle simply has to work can you give us a value for the range well I can assure you that all variants will exceed 500 [Applause] Kilm I have to say it breaks and steers like a Porsche incredibly good feedback via the steering you can feel the power the acceleration but the Maan isn’t just supposed to be a sports car the Maan must be an allrounder that covers the full range of customer benefits and it
Must be recognizable as a Maan we have achieved the entire spectrum and the challenge of implementing this was an incentive for all of Us
The all-electric Porsche Macan is almost here. It has faced a gruelling and extensive testing programme, covering 3.5million kilometres that has pushed it to the limits under the most extreme conditions. Discover what it takes to ensure a car is ready for release, and how the new addition to the Macan line-up was developed.
