@  Mike T : (24 August 2016 - 08:38 PM) Yeah because the injectors don't spray fuel at the intake valves, gumming them up is possible. A good thrash from time to time at redline will do wonders.
@  smartzuum : (24 August 2016 - 07:51 PM) Italian tune-ups for DI engines I read, above and beyond good fuel and proper maintenance. Jap engines LOVE to rev.
@  smartzuum : (24 August 2016 - 07:36 PM) Interesting point Mike..... I'm typically a Chevron guy for gas, so not too worried about gas quality itself. But a good reminder to keep the oil VERY clean and do occasional spirited driving as well.... which it got last night on the way back from Penticton on the Coq. Hard to avoid DI engines nowadays I reckon.... the unlimited powertrain warranty for 5 years is comforting....
@  dmoonen : (24 August 2016 - 10:58 AM) Oh yeah 94 octane fuel :/
@  dmoonen : (24 August 2016 - 10:50 AM) Im getting like 17-18mpg right now with the R32. My whole fuel mileage thing just runs off pure smiles per mile now.
@  Mike T : (24 August 2016 - 05:59 AM) Not bad. I would point out that the best I've achieved in the old-tech B 200 is a bit better than that! The Mazda has direct injection. So watch for valve gunk buildup.
@  smartzuum : (23 August 2016 - 11:53 PM) Best tank so far is 5.85 L/100 km in the CX-5.... and seem to be averaging around 6.1 overall..... incredible.... just got back from 2500 km road trip - through the rockies!
@  smart65 : (19 August 2016 - 06:55 AM) Ours has auto though.
@  smart65 : (19 August 2016 - 06:54 AM) Good choice. We've had a similar model since July 2012. No regrets!
@  smartzuum : (18 August 2016 - 09:09 PM) no led lights or navigation screens.... oops....
@  smartzuum : (18 August 2016 - 09:08 PM) 2.0 litre, 155 hp, and thank goodness, no LED lights of van screens on the base model... cruise, stereo, info display, AC.... all I need! It's a wonder you can get something like this still.
@  smartzuum : (18 August 2016 - 09:06 PM) 65 cubic feet cargo room behind the front row with second row flat, a must for me now.....
@  smartzuum : (18 August 2016 - 09:05 PM) Gone is the Volvo V50 T5 FWD automatic.... I got $4500 trade, which with the tax savings got me $5040 of my $5500 total out of pocket on purchase and tax and repairs... not bad for a years driving.... the mazda has a 5 year UNLIMITED kms warranty on the powertrain.... and 3 years unlimited kms bumper to bumper.... unreal. Looks like it can do 6.0 on the highway, just anecdotally from the trip meter in the vehicle, but we'll see soon enough.
@  smartzuum : (18 August 2016 - 09:02 PM) Tuesday night, I spent about 5 hours on the net doing a bit more looking into new vehicles... and long story short, decided by 2 am Wednesday that I was likely to get a new Mazda CX-5 in FWD with a 6 speed manual.... Went into the dealer at 4 Wednesday and was done the deal by 6... picked up the dark grey base model at 1 pm today, and so far, I'm pretty impressed. Therefore, the k has become an m....

@  Mike T : (14 August 2016 - 07:49 AM) Unscrew the SAM from the front edge of the dash - T-10. Then it's easier to pull the whole thing down and get at the top side where all the connectors are. They're all labelled, molded into the SAM casing. N11-3 with the brown plug.
@  moi : (14 August 2016 - 07:43 AM) PS...I gotta read up on how one discerns which 'connector' is the right one...I imagine there is something already on the forum to show how to identify each connector.
@  moi : (14 August 2016 - 07:40 AM) You guys are much appreciated by this pure amateur.
@  moi : (14 August 2016 - 07:39 AM) I wish someone knowledgeable lived closer to Owen Sound..
@  moi : (14 August 2016 - 07:38 AM) It's interesting that when I started to remove the cardboard cover that hides the SAM the actual unit was already unclipped and dangling...the dealer I got it from must have been monkeying about in there. The thing cranks rapidly but won't start and there is no fuel pump sound.
@  Mike T : (13 August 2016 - 10:07 AM) Yes I should have! oops
@  cadillacman : (13 August 2016 - 09:54 AM) I think Mike should have said N11-3
@  Mike T : (13 August 2016 - 09:54 AM) For clarity, what I called "connector" below in the first post is actually the whole plug or plug head (brown plastic) but elsewhere it means the single electrical contact within the plug.
@  Mike T : (13 August 2016 - 09:29 AM) With respect to replacing the plug head, the plastic bit will be enough but if the corrosion or heat damage on the female connector is too bad you can replace that single connector.
@  Mike T : (13 August 2016 - 09:28 AM) Take out the N-11-2 connector and look for melting. If there is melting, if you are lucky replacing the plug head (repair kit available from Mercedes) will revive the SAM. And that plus both headlight circuits require an external relay to protect the SAM. There are threads in the operations and maintenance forum about this.
@  moi : (13 August 2016 - 09:10 AM) PS....so...how does one clean those "plugs"? Spray? Sandpaper? Mini wire brush? Shotgun?? Just kidding on hat one....maybe.
@  moi : (13 August 2016 - 09:08 AM) Mike T. Thanks very much for the comeback. My little Smart Passion will crank over vigorously but NO sound of the fuel pump running. Methinks it is time for me and "Sam" to have a visit....
@  smartzuum : (12 August 2016 - 09:26 PM) Last chance on canada1 at $6500 before I roll it over 100km soon.... :) If you are quick, you can do the honour!
@  Mike T : (12 August 2016 - 07:32 PM) plugs. Little captive connectors.

I thoought that this might be an interesting discussion to kick off here.How big would a portable 120/240v generator have to be to supply enough continuous energy run an electric car? I'm visualizing one mounted on a small trailer and plugged into the battery's charge circuit. Somewhat similar to a diesel-electric locomotive, where the internal combustion engine generates electricity to run the electric motors which propel the vehicle. It would increase the range of the car, but the fuel economy wouldn't likely be very spectacular. Whatever became of the fuel cell? That would be a natural, if it were developed to the level the original hype promised. Feel free to add your thoughts on this subject.

Consider that a high-efficiency electric motor running of lithium-ion batteries (think: Tesla) operates at perhaps 88% efficiency. A modern, four-stroke internal-combustion engine in a car operates at roughly 18% efficiency. In other words, you would have to supply roughly five times the input energy potential to a combustion engine just to get the electric drive train to run.

Overall efficiency will be far lower than if the ICE powered the car directly (ICE loss plus electric loss).....and the ICE used will probably pollute far more than a road legal car engine would, so it's a double hit against air quality and global efficiency. Far better to buy a new Volt if this is the way you want to go.

The efficiency of an ICE dedicated to a generator would likely be higher than that for one powering the car directly. It would be run at an optimum rpm to maximize efficiency. But there is no question that there are losses. The Jaguar C-X75 uses this principle, but uses gas turbines instead of an ICE to drive the generators that charge the batteries. Such a car can run on batteries when emissions are a problem, but extend range by running the generators when on the open road.

Wouldn't the on-sale-now Chevy Volt be the standard bearer in the plug-in hybrid segment, beating the Karma to market by a full six months? The Tesla Roadster and Model S are fully-electric vehicles. But calling the Karma more refined than the Model S is a stretch, since the Karma just began deliveries, and uses a Chevy Cobalt SS engine to charge an A123 Systems battery pack that is considered inferior to those made by Tesla. The electric motors are off-the-shelf units as well, unlike the custom Tesla units.

Sorry the model S is a giant leap forward from the roadster, take my comments with a grain of salt for I have never driven either one. I was however under the impression that the volt only charged by plug and that the conventional internal combustion engine propelled the car after the batteries were depleted but did not recharge the batteries.

Nice car! To be exact though it is more like a luxury Volt than a Tesla - The Tesla is is a Plug-In EV - Fiskar has an onboard motor/generator for extended range. It will be interesting to see which manufacturer woes the buyers. The cars look very similar. Wikipedia notes that Fisker was fired as the designer of the Tesla S for 'substandard work'. Tesla tried to sue him because he incorporated the best of the Tesla S design into the Kharma. Odd to think of Tesla as the establish vendor and Fisker as the upstart! It seems that the smaller more agile companies are bringing better designs to market faster and with less investments than the big three. Will Tesla be the new GM? Interesting times ahead.

Because the trailer is not visible to driver due to its small size perhaps?

As an aside, Toyota announced that they will build the new all-electric RAV here in Ontario. It apparently uses the Tesla power train and will have a range of about 160km (without trailer!)It would be great if the EVs were supplied with a portable generator that could provide enough charge if batteries run out. If it could give you another say 20km, it would save a tow-truck fee!

The article linked above mentions this:

The micro trailer incorporates intelligent "BackTracker" steering which automatically maintains trailer-to-vehicle alignment during backing to avoid jack-knifing.

Reversing a short trailer is particularly difficult, even for those with experience.
