Porsche Macan EV First Look | Engineering and Technical
We are here sir for the reveal of the McAn EV affectionally internally known as the H2 and this good-looking gentleman is named Robert but Robert please introduce yourself to the boys and girls at home who you are and what you do Jack um well my name is Robert
Myo I’m the director for complete vehicle in the model line Maan uh I’m with Porsche since more than 20 years started with uh on the ice side with my first project was Cooling in the carer GT did several positions was in product strategy and then moved over to the EVS
Did some time in a tyon and uh now I’m here in the uh Maan the first job at por shiing the C GT is quite a first project sir quite lucky all right so before we get into what I love which is all the electromechanical systems and the
Electric motors and the battery packs let’s highle talk about what the Maan e is so this is your first EV SUV for Porsche and it is being sold at the same time as the regular Journal combustion Macon so what are the high Lev figures people need to know you have two trim
Levels you’re starting off with Macon 4 all-wheel drive Macon and turbo maon which is the high output they share the same battery pack they do 100 kilowatt hours 95 usable yeah you’re right ranges for the base model is 613 km range of the uh turbo model beside us is 591 in
Wltp so that is that is a very usable range so you’re looking at a little bit over what 3 miles per kilowatt hour right right talking about kilowatts with a TBO we look on in over boost on 470 KW um looking at the base model
In over boost again we talk about 300 K so over boost is available during launch control and for short periods of time for under wide open throttle applications exactly exactly basically whenever you need full power you get it you get it so let’s walk through the advantages of this product and what were
Your sort of your goals looking at this versus regular mcon you’re you’re the head of the project what were your goals for your engineers well the goals were I mean first generation Maran is a well known as a very sporty compact SUV with a high level of uh everyday
Usability so the the goal for the next generation was to increase both sides so to get it on the one side more Dynamic and on the other on the other side to increase that everyday usability as well these were the big two goals nothing to
Do with being an EV this is about making a better SUV correct absolutely what from an interior perspective though this is the way I’ve always looked at maccon For Better or For Worse is they are big hatchbacks essentially they aren’t the same cumbersome giant SUV that we’re
Used to it has the Dynamics of like a big rear wheeel drive Golf R that’s correct first of all we increased the wheelbase by 86 mil which we’ll find when it comes to the cabin um most of them you find on the uh second row um so
Your leg room as well as your your head room increased quite a lot which makes the car in the second seating row even more comfortable um and of course because you don’t have that big uh Power Trin ice power Trin in the car you find
More space in the car as well as in the front end because there is no more engine in that front end no more combustion engine there’s of course a um electric motor there but there’s enough space for a Frank of 84 L and then for when it comes to the center console area
You have far more interior your space cuz you don’t have a transmission to deal with and all completely right we got plenty of space for cup holders and to put all your stuff all right let’s talk about Interior Electronics this is an EV it is very important to your
Consumers it looks visually similar to a Cayenne I know that’s by Design but it is running different hardware and software correct you’re completely right we designed a new architecture new high performance computers um the system runs on a uh Android operation system but the looks are the same what is the main
Advantage that this is running versus the older systems it’s just faster more compute power yeah it’s just more performance on board as well as a better connection offboard uh if we do anything like um a voice control or um maybe charge planning we will do that um on
The back end to even improve the performance um to really get best performance very very quick charge plannings into the car all right the last thing I’m going to talk about before we head over to the engineering side of all this is exterior design and your coefficient of drag so yes now you
Have a programmable spoiler that can go up and down in the back visually though it does look very similar to a regular Maan but with a better CD correct yeah we um achieved a CD of 0.25 which is with this this um within this class of compact SUVs pretty good I
Would say you’re very and we achieved that by several things we got these uh adjustable um cooling flaps on the front end um and uh we got it completely flat on the body we did the air curtains uh to really get a nice flow around the
Front rims and as I said that adjustable uh rear spoiler perfect with all that said it’s time for us to go walk to the exposed underbody of this vehicle so we can talk about all the engineering sir yeah great All right Robert this is what I want to talk about the meat and potatoes of the allnew Electric mcon Mt or double Wishbone front multi-link rear all the suspension components other than the subframes are aluminum and you have in the US I think air ride is standard
You’re right and then in Europe you have a mix of either steel Springs or air ride that’s correct well the major difference is that we um decided for two well dampers compression rebound can be separated exactly which uh makes your range of comfort to uh Dynamics even
Bigger and then your air Springs are one chamber versus two chamber correct and then the big innovation which I know you guys are very proud of is for the first time ever you’ve been able to package rear steering it’s one one motor in the back versus two on both and you can
What’s the degree of range like 5 degrees or six yeah it’s 5° and we as you say we’re quite proud on that um yeah although we increased the wheelbase as I said we even more decided or opted for this uh rear axle steering to make the car really Dynamic if it needs to
But even more stable when it comes to higher velocities the advantage obviously is that on the one hand if you’re on on low velocity you virtually decrease the wheelbase but when you really drive fast you increase that wheelbase so that makes it really stable on the German Alon and what was the
Reasoning behind not doing your lovely pdcc just not necessary for this vehicle um well not not for this one um yeah that there different reasons uh we won’t go that much into diesel surfing no no worries and in the back you have an optional PTV plus which is a amazingly a
Actual physical differential on an e vehicle yeah but it works pretty well um you will feel it when you have the chance to to drive it it goes sideways is what I need to know right a little bit if you know what you’re doing so what’s the static weight balance of this
Yeah we got a perfect weight balance of 48% on the front axle and 52 on the rear one oh w why why go with that versus like a 50/50 what’s the main difference there well the Porsches are always a little bit uh on the rear axle a little
Bit more we obviously do have a lot of more torque on the rear axle so you want to put on a little bit of more weight so this way you will be able if you know what you’re doing to rear little drive it a little Dynamic what is the how do
You shift power around is it typically a rear buia system how are you shifting that torque front and row it really depends it really depends on what the customer wants normally if you just go straight you will have the major part of power on the rear axle but then it
Depends if you like go Dynam dynamically and want to get it straight again you put quite a lot of torque on the front axle for a short moment it really depends on what you’re doing the last subsystem I want to talk about before we get into the electric motors is how your
Braking system works it is now fully Brak by wire correct you’re correct yeah it is a onebox design so it’s fully Break by wire um and um yeah it’s it you end up with a because you thereby have a a really ra wide range of of degrees of
Freedom so you end up with a really precise paddle feeling um depending on what the road conditions are you got a nice feedback uh to the customer by the brake padle what’s the philosophy then of M Manan EV when it comes to Dynamics I mean Porsche is very good about making
Sure these cars don’t feel like science experiments that you seem to not design your vehicles whether or not they’re EVS or internal combustion so what was the like what were the goals when you sat down your engineers or the team how this was supposed to drive what were your key
Objectives for them well the the key objective obviously is that the customer has a direct connection to the road to the road conditions he has it by the seating position he sits very low we achieved a seating position of up to 28 mil lower than the first CH Maan um you
Got a nice feedback via the uh steering wheel as well as via the uh the brake pedal so you want keep the customer really connected to the street to the road condition to what the car is doing in the moment the the question that a
Lot of people have is you know at least in paper as an engineer you look at all the various subsystems and it’s whether you look at BMW or Mercedes or another premium brand at least in the EV SUV space the individual components all sound very similar they all are air ride
They’re all multi-link cars they all have two Motors what about this makes the suppor your product then right well as you say the the trick is to bring all the good components in and then to optimize the complete system not only optimize the dampers or the Springs um
Or the steering but see the complete system and optimize that and I think we got these really brilliant experts in in chassi Dynamics at Porsche and in my eyes they did a brilliant job in really bringing this car again to an Optimum so what makes this a pora product is your
Ability to integrate all of these electromechanical systems and get them to work cohesively is what you’re saying that’s it uh the trick is you need people who know what they doing next thing to talk about electric motors so regardless if you get the Bas Macan EV
Or the turbo variant you have one motor front and rear the power outputs are D dramatically different as we talked about earlier but are the physical Motors themselves different units they are on the front X we use the same units for the base and the turbo on the rear
Axle the turbo has a much bigger rear motor more torque more power but the Innovations to the PSM Motors that you have front and rear are constant right is the same basic it’s the same basic technology PSM Motors um on the rear axle we use uh cisum carbet Power
Electronics which makes the um the motor even more efficient but which uh gives you the possibility of to to really as well bring more power into it how has your electric motor design changed obviously the big thing is you’ve gotten rid of your two-speed gearbox you move
To a single speed right why is that and how has the rest of the motor been altered I know that’s the big one well yeah it obviously was a longer decision or or discussion in the in the early phase of the project but we ended up
With a really nice rear axle motor with a wide uh wide range of a good efficiency on the other hand with a really great amount of torque so we could really afford to skip the two the two-speed gearbox and go to a a single speed transmission and what’s your
Cooling strategy for your electric motors it’s again uh it’s it’s it’s it’s based on a on a water cooled jacket we cool the stator down as we do have PSM Motors we don’t have that much of a thermal problem on the rador itself so
We just cool the stator on a on a water base okay and then then I guess the next thing to talk about easily is the battery pack 100 KW hour total battery pack size you have how many modules are you working with we do have 12 modules
Um and we can use on on this battery up to 95 uh kilowatt hours of energy and you’ve changed your cell design versus outgoing tyon now you’re running presmatic Prismatic cells correct you’re correct yeah coming from pouch cells we now use Prismatic cells mainly for packaging reasons what is a
Serviceability like can you individually pull each one of the modules out and check their Independent Health and replace each one as they go bad yeah we we know exactly what the status of health is of each module we know the temperature of each cell so we exactly
Know if there if we are in trouble with a module we can really service it get it out and bring a new module in but they share one giant cooling plate correct you’re completely AR what is the range of the cells you’re working with like what’s considered nor noral what is its
Bogey number when does it start pulling power right normal normal temperature range is probably like between 20 and 30° cus uh the upper level is roughly about 55° Cel where we then begin to go into a D- rating and you’re running what high and low temp circuit for your your
Cooling strategy for we we do have obviously the electric motors need a higher temperature level than the battery in the normal condition so we do have uh two circuits of cooling one for the um motors with the um Power Electronics and the other one for for the battery what is your charging
Strategy for the battery pack what what kind of numbers are we working with and what ises the technology that you have allow you to reach those numbers right we talk about an 800 volt system um we charge with a power of up to 270 KW and therefore we reach a charging time we
Talk about 10 to 80% of roughly 21 minutes oh I was reading through your your engineering brief on this you can also essentially break up the system in a two 400 volts right why because there are in in several markets we still find a lot of 400 volt infrastructure and we
We would like to really use that in an efficient way therefore we split the battery into two 400 volt battery put them into parallel and therefore able to charge on a 400 volt charger of up to 150 kilow in a really efficient way so we’ve talked quite a bit about the
Actual battery pack itself why go with 100 Kow hour pack you’ve seen oems go with smaller numbers and you’ve seen your American friends go with much much much bigger bigger packs why 100 kilowatt hours well as I said the the main goals for this car was really
Sharpening the Dynamics so we opted for not that much weight in the car what we want to achieve are really fast traveling times from point A to point B so we talk about fast traveling so we op it for really fast charging and therefore not to bring another whatever
200 kg of battery into the car to really keep the car uh very very Dynamic so you’ve had The Misfortune of answering all my questions for the last hour or so I’m good on and off camera and you’re about to answer God knows how many more journalists but the question I have for
You is why would your customer buy this vehicle like why buy this over internal combustion maon or a a different SUV from a different brand what about this is so special well um with a Maan first generation we offered a very successful model the sports car in the compact SUV
Class um and we sharpen both sides Dynamics as well as everyday usability and therefore the customer again will find a very sporty compact SUV with um all Dimensions I mentioned increased so this is just in your eyes a better SUV regardless of the fact that it’s EV or internal combustion correct correct
Perfect so I can’t wait to actually drive this thing in a couple months so thank you very much for your time Robert thanks for being here Perfect
