I drove a 5 speed diesel Hyundai Atos in France.  Fuel economy was over 50
mpg equivalent.

GDI engine is about twice as thirsty as a 40 year old diesel.


But the old Rabbit diesel had about 40HP (when new) or so?


Somewhere around 40-50 I think.
Cruze has bearings sized for 153hp. And it gets 50mpg at a steady 55mph, 
in a car considerably wider and 50% heavier than a first gen Rabbit. I 
think a 4sp Rabbit got about 50 highway, on fuel with a higher energy 
content. 1.6L Diesel Cruze (137hp) will do 70+mpg if you drive 55.

A 1.4L Cruze runs about .25-.28 gallons per hour, or closer to .35 GPH 
if the A/C is running.

The service rep at the dealership said there is a separate battery in the
Bluetec models that handles this feature ("Ecostart"), so the main battery
is unaffected.  Not sure how all this extra work affects (degrades) the

Re: [MBZ] “Special” Battery?

2022-09-26 Thread Randy Bennell via Mercedes
We had a rental car a couple of years ago that had the auto stop and 
start feature. It was a Chevy Malibu if my memory serves to be correct.


It was actually very seamless. I didn't realize it was doing it for a 
time. Stop at a light and the motor would shut off. Lift your foot off 
the brake and it would start and be running ready to go before I had my 
foot back on the gas pedal.


I see no point to it and assume it would put a lot of strain on various 
components but I was amazed at how smooth it was. Of course, we are 
talking about a new vehicle with hardly any miles on it. Who knows what 
it would be like as it got older?

For something like the Prius (?) this technology makes some sense.  The 
starter/motor is
large, and direct drive.  (No gears.)  Very little to wear, in other words, and 
with a truly
massive battery behind it.

Re: [MBZ] “Special” Battery?

2022-09-26 Thread mitch--- via Mercedes
When the 2016 Chevy Cruze obtained start-stop technology, it came with a 
beefed-up starter and a large AGM battery, along with smart charging and 
a current sensor in the battery cable so the car knows amp-hours in vs 
amp-hours out.  Certain temperature parameters must be met, climate 
control must not be in MAX/AC or DEF settings, and battery state of 
charge must be high in order for it to stop the engine. And if you're 
waiting for a train with your foot on the brake, it restarts in 2 
minutes.


I just checked with GM Parts Outlet, the battery is #1 on the battery 
parts diagram, but they don't give a corresponding part number or price. 
I assume it's $200-300.

goodness.

As for a special battery because they do this, I’m calling BS. I have
often wondered if it’s harder on the battery and starter in cars with
this feature, or if the starter is somehow re-engineered because of
the much higher duty cycle.

Re: [MBZ] “Special” Battery?

2022-09-26 Thread Allan Streib via Mercedes
Not that I've ever heard.

Wife's car has that stop/start and it has a standard-looking 12v lead/acid 
battery.

I hate it too. I always disable it when I'm driving. Can't see how the pennies 
in gas it might save offsets all the extra wear on the starter.

Re: [MBZ] “Special” Battery?

2022-09-26 Thread dan penoff.com via Mercedes
I know nothing of these setups, other than to say that I had a BMW 3 series as 
a rental this past weekend that had that infernal “shut off the engine at every 
stop” feature which I was able to disable, thank goodness.

As for a special battery because they do this, I’m calling BS. I have often 
wondered if it’s harder on the battery and starter in cars with this feature, 
or if the starter is somehow re-engineered because of the much higher duty 
cycle.
