Smartcar ?

A friend just got a Smart car diesel, (got it for half a song), because it has a glow-plug problem, apparently 1 is bad, and asked me about it as I have a Mercedes diesel.
Anyone here have any knowledge of these things they could pass on ?

Engine is under the rear floor cover....I'd open 'er up and look for obvious signs of where the glow plugs are mounted. There will be three of them. I bet that its not a big deal to replace them.

I wish we could have those here, but alas our failed emissions laws claim a 1 liter diesel is dirtier than a 6 liter gas v8.

Some how I bet the situation is not that simple.

I imagine that the reason we cannot get them is that they have not been submitted for certification.

What kills me is these smokey two cycle weed trimmers etc are legal and probably pollute five times as much as a smart car or such.

No smoke should not be visible from a modern 50 to 1 oil mix 2 stroke unless someone is increasing the mix. ( I remember the days when 16 to 1 was the norm. )

Many of the trimmers and such are going to all position 4 strokes.

The smoke (which should not be visible as 97 SL320 said) is not the problem, it's the unburned hydrocarbons. All-position oil lubed 4-strokes are not the ideal answer. Stihl and Shindaiwa have the answer with their 4-stroke engines that run on mixed fuel. These are true "all position" engines.

There are some federalized CDI Smarts in the US, look around they pop up on Craigslist from time to time. I know a local guy who has had like 10 of them.

Jerry,
We own an '06 smart CDI. Great little car.

The glow plugs are available and can be replaced. This place sells them Glow plugs: shop.flyingtiger.ca

If I were you, I would head over to Club smart car and ask your question there. There is a ton of info on that site about those cars and a number of knowledgeable owners and mechanics.

Your friend should make sure problem IS the glow plug and not something else. Surely previous owner wouldn't have offloaded car just because it needs a glowplug?

True, however they have / had issues with sticking / carboned valves early on. Not sure if that has need solved. They do sell a carbon removal solvent that is supposed to be like GM TEC ( Top End Cleaner ).

Briggs & Stratton and Honda have all position engines that run on straight gas, the crankcase is filled with regular engine oil. The concept is that the oil is a fog and the bearings are needle like a 2 stroke from what I recall.

I've always wondered about those. Especially the safety factor on them in an accident. I did a google and the first thing I found was a video of a smart car vs. mercedes crashing into each other...Video: Smart car jarringly stupid on safety, crash tests show | OregonLive.com

What those tests show, is that a big heavy car will come off better in a head on collision with a small car. That would have been something we could have guessed. Many years ago, the large corporation I worked for insisted we only rent full size cars when travelling (for safety reasons).

The smart actually comes off quite well in real world collisions. They essentially have an integral racing car type cage that protects the passengers. I know of a couple of cases here in Ontario where the car performed well in a crash. In one , driver had to swerve to avoid a collision, ran up on some concrete barriers that flipped the car - it rolled about 3 times and ended up on the now deflated wheels. Car was a complete write off, but driver was able to open door and get out!

These are mainly city cars and are unlikely to be involved in high speed head-ons with large cars. I think that is how the manufacturers responded to those tests. Many other tests have been done previously including those that MB have to do for all their cars before being approved in Germany.

We are happy with our car. It does close to 60mpg (US) on diesel. I don't think the newer gas smarts are attarctive in that they only do about 42mpg and use premium gas. Not very good for a compromise car. But nevertheless owners love them.

The video at that page wouldn't load for me, probably just my browser, but I looked at the IIHS offset 40 mph crash video on YouTube.

I don't see any particular problem. Smart or not, Mercedes can't repeal the laws of physics and there you have a tiny car colliding with a much larger/heavier one. Frankly the bigger car didn't exactly emerge unscathed either, it had more damage than I might have expected.

If you hit a Yaris with a Camry you'll probably get the same result.

Actually, it's really 2 Mercedes crashing into each other. The Smart car is amazingly strong despite its size, and the Mercedes engineering shows if you look under the interior panels.

It's still safer than a motorcycle, and lots of people, including me, ride those.

Anybody know what it takes to get a diesel Smart into the U.S. and how the performance stacks up against the gas version?

Also, speaking of motorcycles and Smarts, they can be combined. Observe:

SMART with 192HP Kawasaki ZX10R Engine - YouTube

smart turbo with hayabusa engine - YouTube

Whew! Back from the land of crash test videos.

Smart Four Two is definitely impressive in it's ability to protect the driver - considering the smaller mass of the car.

I still wouldn't want to tempt the laws of physics on the highway but I'd drive one to the supermarket.

What kind of mileage do the diesels versions get?
