Speed Limiter

Thu May 15, 2014 11:02 pm

I think a speed limiter addition to the car would be great. I have Speed Limiter and Cruise Control on my Merc. I hardly use the Cruise Control, but the Speed Limiter keeps me legal so I use it a lot.
I haven't got my i3 yet, but I suspect that estimating my speed by ear will be harder in it so Speed Limiting will be even more vital.
I can't understand why it isn't already available!
Noteworthy cars I've owned previously: Lancia Aprilia ... 20kWh i3 Rex.

I've never driven a car with a speed limiter, only ones with speed warnings. If like a speed warning, the speed limiter has only one setting that requires a trip thro the settings hierarchy to change it, I should have thought that cruise control would be a better way of staying legal because all the cruise controls I've ever used could be reset to a new speed with one touch, allowing them to be changed easily as the speed limit changes. By contrast a single setting speed control, unless easily reset on the move, is only really useful for the highest speed limit which will be encountered. Using cruise to stay legal has a couple of other advantages, it's easily overridden to go faster if safety requires (eg to shorten what might be protracted overtaking where there is no escape route) and a constant speed will usually be more efficient.

The other option would be to configure the max speed for Eco Pro to whatever you normally use on your speed limiter. If I've understood the manual correctly, from a safety viewpoint, this has the advantage that it can be overidden instantly if necessary by flooring the accelerator just as you would for kickdown on an auto.

We have a Citroen Picasso that has both limiter and cruise control. It works exactly this way - you can set a speed from the steering wheel but over ride it by mashing the throttle. Around town, a limiter is a much better device than a cruise control. On the highway, the cruise is better.

The standard BMW control for the limiter option is as easy to use as the cruise control. Single button to activate and then same controls to set the speed as with cruise. Again "mash" the throttle to override at any time and same button to resume. If I remember from the test drive those same buttons are there.

There is also a max speed limit warning option with a boing. So I think BMW has Mercedes covered. ;-)

Better would be to link the limit speed to the speed limit camera detected speed as an option? (Rumour is that EU was going to mandate that for safety reasons in built up areas)

Surprised you don't use cruise control. Similarly, people are usually surprised when I tell them that I use cruise control 99% of the time. It is, without fail, the single best thing that can be done to increase gas mileage--all of the little fluctuations we would do otherwise add up to wasted fuel. My current car (2007 VW Passat 4-door 1.9 TDI) is rated for around 45 mpg. This morning's drive to work I had 61 mpg (~15 miles 70mph highway speed, ~15 miles 30-40mph speeds). You betcha I had cruise set on 30mph.
Avg ~72 mile/charge over ~9k miles

Cruise control and ECO-pro are the absolute bees.

535d 8-) nearly matches the VW.

The i3 does have a speed limiter. Well, kind of ;) ... Just engage EcoPro mode and the car will automatically be limited to 110 km/h (+/- 68 mi/h).

You can even change this value; go to main Menu, then EcoPro sub-menu. Among other things, you can tell the car what is the authorized top speed when EcoPro is engaged.

My previous two 5-series had both cc and limiter. As the i3 has a adaptive cc, I don't need the limiter as it limits itself.
I used the limiter at the 5 series a lot in heavy traffic.

I have this feature on my Renaultsport Clio and it is the BEST feature for town driving. Living in London,UK the speed limit is 20mph across most of the city and the place is covered in speed cameras.

Having the car set to 20mph max with a limiter gives you more time to focus on crazy bicycles and pedestrians. Cruise control is just dangerous in town. The key difference being if you need your foot on the accelerator to go with a limiter so you still have control over your speed.

I'd probably drive straight over to the Camden i centre and by an i3 today if they had that feature.
