Porsche Crest The Score is: Porsche 1 - Mercedes 0



We are experiencing single digit temps in the Shenandoah Valley. Yesterday afternoon, the wife's Mercedes (diesel) wouldn't start (She was at work and obviously, didn't have it plugged in). She got home with a co-worker, got the keys to the 944, which had sat for almost two weeks, and it fired up immediately.

Needless to say, she drove the 944 today. I'll probably have to wait until Sunday (expected to be in the high 30's) to go get the Benz. Otherwise, I'll be dragging a generator out there to power the block heater so it'll start. Can't complain - the Benz has over 250K on it.

Cheers

-42 F around -41 C a few days ago.

ISUZU Rodeo = 0

You are comparing apples to oranges? Diesels are always troublesome when it is that cold.

I have 3 Mercedes gassers. All 3 always start. One of them is 23 years old.

And diesels will never overheat - not on the hottest summer day, stuck in traffic, with the AC on.

I think its a fair comparison.....

If you are going to sell a vehicle gas or diesel or electric it better be able to handle the temperatures it has to operate in....

I don't see the volkswagen TDI's putting disclaimer stickers on them to not drive them when its below 0.

Actually, this was the first time the Benz would not start - We usually only plug it in at night when it gets below 15 degrees - The wife love's the fact that she gets warm air instantly. I was just surprised that it didn't start in the afternoon.

I don't plug in my diesel pickup (Cummins Turbo Diesel) unless it gets 5 degrees or below. It always starts (265 K miles), but smokes big time if not plugged in when it's that cold.

We both love the diesel's - and she really likes the 944.

It's killing her co-workers that she now has two cars at work - Benz and Porsche. She often has a co-worker ask if we'll sell either car to them.

Of course you can drive them when it is below 0 F. The trick is starting them. Without a block heater or fuel additives, it can be dicey with any diesel no matter who manufactures it.

Diesels require much more power to turn over than a gasoline enginesby virtue of their much higher compression ratio (somewhere around 20:1 as opposed to somewhere around 10:1). That is the reason my diesel Suburban has two 1000 cold cranking amp batteries (6.2L w/ 22.5:1 compression ratio). If the batteries power output drops much below 12V, the starter will fry itself. Since batteries are chemical reactions which slow down as the temperature drops, it's wise to make sure your batteries are in top shape at this time of year. We hit 26F this morning here in central Florida, the 'Burban started fine, just shook like crazy for the first 30 sec's or so.

I love driving the 944 in cold weather, as long as there is not snow on the ground. The cold air feels like another 10 hp. When the temperature is below freezing, my n/a has balls.

Saturday, it was a balmy 36 degrees. The Benz started immediately. My wife then drove it home.

Today, it was 9 degrees, expecting a high of 15. She drove the Porsche today. The Benz is comfortably plugged in.

HEY SCOTTMANDUE - I grew up in Monterey Bay, living on the peninsula itself - got transplanted to the other coast courtesy of the US Gov't ofter an extended vacation overseas. Was in Monterey when "Monterey Pop" was filmed. Saw the original Raiders play in '63 (Would have lost money last night if I was a betting man). The Shenandoah Valley usually is mid-30 to low-40 for January highs. This is as cold as I want it. Those guys who live in the north where it really gets cold have a completely different way of living - They have to prep the vehicles for the weather. Even the diesel fuel is "winterized". We don't get winterized diesel here - sometimes we add a fuel conditioner to prevent gelling. Obviously, I hadn't done that.
