In Baytown. Job is La Port, Texas. Good question. It has had a whine not normally there since I got it back. It has been running great though. This happened all of a sudden. No warning. It did shift a little hard a few days ago though. I was running 70 mph and got warnings. Also not heard of clutch problems with these cars. I will get to talk to dealer tomorrow. Getting loaner car. I thinking I may need to trade.

Yup, the more common one is the Dual Clutch Transmission, aka dct.   It has two separate clutches, each handling alternating gear sets.  One engages as the other dis-engages.  That's why they're so smooth.  Honda has offered this on some of their motorcycles, notably the Gold Wing.   Many high end sports cars use them.

Then you have the twin disk. Yours isn't flat towable, while the manual is. There's a difference in the option code.

The business of towing the 453's came up a year or 2 ago.  I asked the local dealer, one of the two biggest in Canada.  Both Service and Parts said no.  This would be for the Automatic.  I'm not aware of a Standard being available.  I'm also told no more Smarts are being exported to NA after 2019.

So someone trying to prove me wrong posted some documentation contradicting what I'd been told.  Put something in this setting and disconnect something else, can't recall exactly.  So I figured OK go ahead.  It may be a US thing compared to  Canadian...don't know.

What I will tell you is that there was a brand new 2016 in a Parts bay with the transmission removed because the owner who had a Motorhome towed it and destroyed the trans.  This after being told it was towable by sales dept.  The dealer wound up bringing in 2 transmissions, the first one being wrong so a second was shipped in at dealers expense.  By this time the owner bought something that was towable and was refunded his purchase price. 

Eventually the car was repaired and sold with full warranty.

So, I take draconian measures to load mine safely.  Others want to drive up...hey, go for it.  As a member said, ' it is about mitigating risk'.

Or like in Robot wars or Battlebotts, you don't build to win, you build to try to not lose...or something like that.

So as the lawyers say, 'govern yourself accordingly'

The ONLY 453 model you can tow 4 down is the dual clutch model. I'm on the road right now but when I get home Monday, I will post up the procedure to tow the car that Mercedes Benz smart division sent me. Not a dealer, not a tranny guy nor someone that slept in a Holiday Inn Express last night. The car manufacturer themselves.

I am seriously considering getting an 2014 451. I can pickup one up for 5k. This is going back thru insurance company and it took 2 months to get it back the first time. Really don't like the turbo lag on the 453s. Don't really care for the shifts on the 451 but it will jump out in traffic where the 453 won't.

Rick, my 2013 got bettter mpg. It depends where you drive it. Pull out from a dead stop at an turn and I need to put foot out and push. Now that might have something to do with stability controls. Rolling just a little and it goes. But I got in the 40s mpg with my 2013. Best I ever got with the 2016 is 35. averages bout 32. I like the 453 but it is no longer dependable. And I don't like it 6k better though. People on the Smart forum have called turbo lag on there dangerous.I tend to agree. I have to drive in Houston some.

I've towed a 2016 453 behind our motorhome for a couple of years and at least 8,000 miles. Seems to be fine to me. I follow the published procedure that Mercedes says to use. From Mercedes. Not some forum. If you want to tow, talk to Mercedes. I'm not posting anything because I'll just be told that it is all wrong, can't be done, etc. Do your research, but I assure you that you can flat tow a 453. I'm sure David will post the proper procedure. Here is a pic - I put a drop hitch on it so it is perfectly level now. Rrowb0nn0z-MvZo7N35aRj1zs_vZEA4-N-ueEDanH6fg-yhcCzN9fhN3fDkU5nOApXaz3vzK7JoVKUd5jDS5CsaAfiCejNOoekEPDGNgOXdNO5UGfGtPn7Y_KBF2FmG32IvkB4WQT6usi-tecgxCDYGoryYYafiMrJ0-Axp7mqxQIlwU7j8NP7YtrzI-5bCJtiXaLg-QfGGBZNeMjufRIIwwoC94rqlkICy97vsuzBwEmuL9M4y1DJ7SDd12vf1EXjDq1J-aUM_O20ey-6VGTCNpynyeqX9QX4hxx7X7JjsIAnkxZ35n7FtcGHnR0LI2B7n5FRXMVCPQxn1gF8p1yotKAByKt5sLmIpTlO6U-FoOYQy3_7_3vylEML1no0yTuRcsvi0tlCywtEkGDJkrSjInn40iHITQc9rZ4thdE5qrUFvuUjE7eZpqWrh5oQaX8OsIEtalXWpS6glRw8oFoByWlHigmxH7XeyWyX6QORcRqZBQK_FNnkTT9u1FvlEXg0i7jbnZ51n9ZzLWgmDBAQfz-pje6_s4S19I0nG1Ik2pdXXKSsvp5iX5cgaAl7Ksd2Q7F8vkPQbA0Qw3PPumUelsGbuCsc243fwPI0K4wfUzy_Qd5gJFi7XkinkehlpM0RfvDg0IeBSaBV4Gz258PIPZGoALacd1zEIOeIioYNWwsrnvBPK0VX2H=w2219-h1248-no
