2014 E250 RWD at 6,900 miles, 11 months old

I just love the car the way it runs with fuel mileage consumption going at over 50 MPG on highway. I think this car runs just as smooth as my ex-car 2012 E350 Bluetec, if not better. I miss nothing about V6. I had no problems at all so far. Transmission is much smoother now that it is broken in. It just glides.
I thought you e250 owners might like to hear a story like it.

2015 E250 BT 4M
E250BT performance

Yes, I echo your comments comparing the E250BT to E350BT.

I find that E250BT is faster off the line, with its negligible turbo lag compared to the E350BT. With my 4Matic version, the E250BT handles better, the steering has more feel and both the transmission and the ride are improved.

On wet roads (inc. snow and ice), the 4Matic advantages are very evident. The engine's high torque output is effectively balanced between front and rear axles, with none of the RWD slippage that I had with my previous E350BT.

As you mentioned, fuel economy is even better with the E250BT.

The two turbos only smoothe out the power curve, its actually a 1/2-full second slower 0-60. Not a problem though, it feels faster than it needs to be. And thats very interesting, the 250 has 4matic huh? Wow. I kind of like making the back tires step out, but thats very interesting. I find both cars to be perfect ownership material and wonderful value.

OM651 vs OM642 is really a matter of taste.

Fuel economy is better, start stop helps. People have reported 50 and up, quite astounding. I maxed out 41 HWY sofar... Sure in 10 years electric cars will get 500mpg range and hybrids will get 100 mpgE but for the next decade, diesels are the most rounded car.

In our moist Northwest climate, 4Matic works so well on wet roads. RWD E250BT is not even offered in Canada. With 4Matic, there's no more rear wheel spin like I used to get in my E350BT. So the E250BT's launch is faster up to about 40 mph, then the E350BT would catch up and pass it. I found the E350BT's turbo lag rather irritating in city driving - never a problem though on the highway, where the V6 is the more powerful passer.

When comparing F/E figures, actual fill data is the only accurate method. The on board computer of the E350BT was very optimistic, by 13% for my previous car. The OBC for my E250BT is more accurate.

It remains to be seen how long it will take for electric car batteries to progress, for both range and storage capacity. The best one so far, the Tesla S with the 85 KWh option, is only good for about 400 km (240 miles) under IDEAL conditions (65F+ ambient temp, level highways, no strong headwinds). The E250BT has the equivalent of over 800 KWh in its fuel tank, which can be filled in under 5 minutes !

The other EC problems are the long re-charging times, sparse infra-structure for 'quick' re-charge and the diminished range as the batteries age. For example, BMW only warrants the i3 battery for 70% of its claimed range. Subtract another 25% of claimed range for typical winter driving temperatures and you get a car that is only good for about 50% of its published range, or about 70 km (42 miles) !!! The BMW i3 without the range extender engine (Rex option)) has a very limited range in real world conditions.

I went from a e350bt to a tesla. Most ppl forget that you have a full tank every morning. So the range only matters the days you drove over 200 miles a day in winter or 250 in summer. The motor is silent. My BT not so much, esp under 40 mph. The torque is instant unlike the BT. It is a way different car. I drove 3k mi a month so the BT was a great car for that which I had 600 miles range but the tesla is 100 times better in every aspect. Costs a arm and a leg too. But it's really like nothing else. Go test drive one and you will see.

I remember how many times you said your e350bt had "gobs of power" before the e250bt. The tesla has that times 10 since it's instant and at all speeds

Yes, having read various reviews, I do not question that the Tesla S has 'gobs of power', but it comes @ a purchase price that (in Canada, at least) is twice that of a loaded E250BT 4M. For long distance touring through remote areas, the limited range Tesla is problematic.

The Tesla's reliability is also in doubt, according to www.truedelta.com. But, it certainly is a great looking car !
