Having suffered through VW ownership experience, I'd never purchase another or anything connected with them. The maintenance was 22 cents per mile over the 95,000 miles I kept it ...
[Corrected]Tesla starts out costing at least $0.038/mile - more if you drive miles per year. We don't know what Tesla's costs will be after the warranty period is up. [/Corrected]
BTW, VW != Audi. VW != Porsche.
Model S service costs at least $1900 for 4 years/50K miles.
Audi S6 service costs at most $800 for 5 years/45K miles, and is not required to keep your warranty intact. For $1230 more, you can get service through 75K miles/7 years. Audi service prices are negotiable, btw.
Driving for three hours and having a comfort or food break for twenty to thirty minutes is pretty normal regardless of vehicle type.
Let's be realistic here. Early reports are that it takes 45 minutes to go from 25% to 75% charge at the Superchargers. You've got to be brave to drive down to 5% regularly, and even then charging to 55% only gets you another 135 miles. So that's a half hour every 2 hours of driving, not 3.
A BMW M5 is considered by some to be the pinnacle of sedan technology...
I appreciate Zythryn's perspective that the S550 is a dog compared to the Model S. I wonder if Zythryn had driven the MB E63 (or M5 or S6) if he would have arrived at the same conclusion.
The M5 came in last in
Car and Driver's recent comparison of Audi S6, Mercedes E63 AMG, and BMW M5. The S6 won and is the least expensive of all 4 cars.
If we look at comparable costs, a fully loaded MSP is about $103K while an S6 without the options that Tesla doesn't offer is about $75K list (and negotiable downwards). Save another $1K in service costs over Tesla (I
never thought I'd be saying that!), and you're at $29K more (plus taxes) for MSP over S6. At $5/gallon and 20MPG (17 City, 27 Hwy), S6 is costing you $0.25/mile. At $0.11/kWh, MSP is costing you $0.037/mile. Let's say S6 costs $0.22 more per mile. With a $29K difference, you'll need to drive at least 132K miles to make the costs equalize. If you option-up the S6, about 95,000 miles is the cross-over. Of course, gas could go up to more than $5/gal.
They both have Google Maps (although right now S6 does a better job integrating it with the Nav and includes 3D), both have adaptive air suspensions (3 levels in MSP, 4 in S6), bluetooth, good stereos, MSP has 40GB storage while S6 has 20GB, S6 has CD/DVD player and SD card slots while MSP has USB, both have rear view camera (but S6 has guidelines that move with the steering wheel to show you where the car will go) both have about the same level of keyless entry altho S6 requires you to push a button to start, both offer WiFi and can be built-in hotspots, both have HID headlamps and both have static cornering lamps (S6 has optional all-LED lighting), both have 35 aspect ratio tires, both have CF interior available, S6 offers dark headliner which is nicer with a black interior. Both have sunroofs and Homelink. S6 has door pockets and center console storage. Rear window of MSP doesn't roll down all the way - I don't remember on S6.
Both cars seat 5, but the center hump of the S6 makes the rear middle passenger have to put a foot on either side, which will cramp the footroom of the people on either side. Headroom is way better in S6 for both front and back passengers, even with sunroof on MSP. Headrests are fixed in front for both. Rear headrests in MSP are too low for adults - on quick accelerations a 5'11" person will literally hit the back of this head on the roof pretty hard (from experience). Front to back legroom on MSP is better, but rear seat is too low so your knees are up high. Rear seat on MSP is more of a bench, which is great if there's just one person back there who likes sitting sideways - S6 bench is more sculpted. I'd say overall rear seats on MSP are better for kids/shorter people or 3 people while S6 overall is better for 2 adults - but I think this is a situation to situation thing where one car is better for one set of rear passengers and another is better for a different set.
Rear trunk on S6 is huge. I haven't done the volume number comparisons, but it looks bigger to me than the below parcel shelf storage on MSP if you exclude the foot well. With footwell, I would be surprised is MSP volume, even usable volume, is bigger - and of course MSP offers the frunk. Since frunk is locked like a trunk, MSP easily wins the storage/cargo comparison, especially when you add the rear seats folding down.
For $6K more on the Audi you can add Heated steering wheel, Heated rear seats, Power-folding, power-adjustable, auto-dimming, heated side mirrors with memory, adaptive cruise control with stop & go, active lane assist, side assist, pre sense plus, Night vision assistant with pedestrian detection and head-up display, Parking system plus with top and corner view camera system (which is really cool, btw). For $1.4K more you can get LED headlights. I think that most of these things won't be retrofit-able onto MSP, at least at decent pricing.
EDIT: I was remiss in not mentioning the 17" touchscreen. I think Tesla's done a good job with usability, and having a big screen is great for the backup camera and maps. I do think it might be a challenge for Tesla to keep nesting levels to a minimum as features get added to the car. Some things, like volume control, are saved by having a dedicated button on the steering wheel (although I don't know if that's always truly dedicated), but that obviously can't be used for everything. In the end, I think the touchscreen is a plus for MSP over S6 - or at least will be when Tesla finishes the Nav feature.
Now there's driving. As nice as the S6 is for an ICE car, the MSP is way smoother. The S6 may have a super advanced 7 speed double-clutch transmission, with 4 levels of aggressiveness and manual override with paddle shifters, but
the Tesla drivetrain is the best on the planet. The S6 may be smooth for a twin-turbo V-8, but the MSP is smoother and better at any US legal speed. Autobahn drivers won't like MSP's top speed limits. I haven't driven either car enough to know, but at first blush both air suspensions are really really good. MSP seems to stay flatter in the curves when being pushing hard, but the S6 is no slouch. The S6's steering goes really light at really low speeds, so parking is easy, but tightens up nicely as you go faster. I haven't played with MSP's settings, but its steering boost also seems to do a very good job. The MSP test drive car I drove was too light for my taste at higher speeds, but that may have changed with production models. I might be driving a friend's today, so I'll report back.
So, where does this leave us? As expected, it depends on your priorities and needs. If you're ecologically minded then MSP is the obvious choice. Want HOV access? Have 5-7 kids to take with you or need fold down rear seats for longish cargo - MSP. If you value drivetrain smoothness and low rpm torque, then MSP as well.
However, if you're concerned about headroom, or a car that'll fit on narrow roads, in parking spots, or even just into your garage, then S6 might be better. If you're a techie, then except for drivetrain, S6's options for the driver blow away MSP's available technology.
I'll just touch on aesthetics, even though it's so personal. Tesla's styling is what I'd call Aerodynamic Boring. Many cars look the same since that's what satisfies the aerodynamics gods. I'm always trying to spot Model S's in the wild, but the car that catches my attention most is the big Hyundai hatchback. From the rear it is styled very similarly to Model S. OTOH, Jaguar XF and Porsche Panameras stand out very clearly from all angles. The Model S has too much chrome on the outside. The black interior needs a dark headliner option. Finally, I've noticed that MSP's leather seats get wrinkled after just a few uses. Others have noticed it, too. Hopefully this is something Tesla will address as it makes for an unattractive look, which can only get worse as the months/years go by.
I really want to love MSP. It's an extraordinary effort as Tesla's first ground-up car. I totally get why people just love it.
But, at the end of the day, it appears that the target demographic Elon architected the car for isn't quite me. I don't live in the suburbs with wide roads and big parking spots. I don't have young kids to put in the back on a regular basis. I've got big kids and adult friends. It's ironic that I bought Roadster to tide me over until Model S, but now I've solidified on keeping Roadster as my daily driver and waffling on Model S as the family car. If you had told me a year ago (Oct test drive event)( that I'd seriously consider another ICE car, I'd have laughed. And I guess I bet $5K on that. I'd hate to lose that bet, but I've got to what's right for me and my family. At this point, any car I get will be a compromise. I just need to figure out which compromise is best for me and my family.
