Just ten years ago, cars like the 2002 Toyota Prius traded performance for unbelievably-high gas mileage, bringing the concept of eco-friendly gasoline electric hybrid cars to the masses.
Recently however, automakers like BMW have used full hybrid technology to give high performance luxury cars like the 5-Series a gas mileage boost without compromising on performance.
But with an expected gas mileage of around 31 mpg combined -- and some reports citing it as low as 26 mpg at best -- is the ActiveHybrid 5 really a green car, or is it time that we realized that Hybrid drivetrains aren’t necessarily always green?
Yes, It Really Is A Hybrid
While 36 mpg might sound low when compared to the gas mileage of cars like the 2012 Toyota Prius and 2012 Honda Insight, both the Prius and the Insight make some significant sacrifices in performance at the altar of fuel efficiency.
Take acceleration. Both the 2012 Toyota Prius and 2012 Honda Insight take around 10 seconds to hit 60 mph. The ActiveHybrid 5 does it in 5.7.
But while the BMW ActiveHybrid 5 is both faster and less fuel efficient than either of the two kings of gas mileage, it is also a real hybrid.
Let us explain. Unlike previous generation 5-series hybrids -- whose mild-hybrid drivetrains could not provide electric only operation -- the BMW ActiveHybrid 5 can travel on electric only power at speeds of up to 37 mph. For city driving, BMW claims electric-only mode will carry you as far as 2.5 miles, provided you keep an average speed of 22mph.
A Different Market
On paper, the BMW ActiveHybrid 5’s gas mileage looks mediocre, especially when there are so many compact and sub-compact non-hybrid cars on the market that can get a gas mileage of more than 40 mpg.
But the ActiveHybrid 5 isn’t meant as a car for eco-minded consumers who want the greenest possible car available.
Instead, the ActiveHybrid 5 is BMW’s latest entry into the luxury hybrid market, currently dominated by cars like the 2012 Infiniti M35h and the 2012 Lexus GS 450h. At a stretch, BMW buyers might even look at the 2012 Lincoln MKZ Hybrid.
Just like you wouldn't compare apples with oranges, you can't compare the BMW AcitveHybrid 5 to subcompact high gas mileage cars or eco-minded hybrids: instead, you have to compare it to similar cars.
Have Your Cake, Eat It Too?
From the perspective of a long-standing BMW driver, the ActiveHybrid 5 offers the best of both worlds -- a car that they know will give great performance and quality while simultaneously saving them money at the gas station.
More importantly, it helps introduce buyers who traditionally wouldn’t entertain buying a car like the 2012 Toyota Prius to the concept of owning a hybrid car.
While it may not get anywhere near the gas mileage of a car like the 2012 Toyota Prius, the 2012 BMW ActiveHybrid 5 will help get luxury car buyers out of high-performance, low gas mileage cars into something that is familiar, but also greener.
There’s more. With the BMW i3 electric and BMW i8 plug-in hybrid due to launch in a few years’ time, the ActiveHybrid 5 could be the stepping stone for many luxury car buyers towards an even more environmentally-friendly car.
But Is It A Green Car?
On paper, the BMW ActiveHybrid 5 doesn’t look all that green, but compare it to other similarly-sized, similarly-priced luxury cars, and it becomes apparent that it is a lot greener than some of its competitors.
Ultimately, an improvement in gas mileage of even a few miles per gallon is a good thing, especially when it introduces car drivers to a technology that could lead to even greener cars.
For that reason alone, we think it is fair to call the BMW ActiveHybrid 5 a green car when comparing it with other luxury segment cars. Beyond that however, it starts to lose its green credentials.

BMW 528 27 mpg
BMW 535 25 mpg
BMW 550 18 mpg
What is a 550 and why is its mpg so bad. Which model BMW should the ActiveHybrid 5 be compared to.
Comparing the ActiveHybrid 5 to the existing 528, there would seem to be little, if any, improvement in mpg.
And I agree with CDspeed. compared to what? It's not meant to compete with a Prius. Not for me, but even incremental progress is still progress.
Future-more, let's not judge them on absolute mpg, but in terms of improvement. Also, let's use the 335 non-hybrid as the base and optimistically use 31 mpg for the bmw hybrid. Here is what we have
non-hybrid hybrid improvement
Honda Civic 32 44 38%
Ford Fusion 25 39 56%
BMW 335 25 31 24%
So at best, there is a 24% improvement for BMW which is far worse than for the other vehicles. Add to that the absolute consideration of 31 mpg, and we have an un-green car.
So, are we supposed to be surprised that a car with a much bigger engine and more HP gets worse mileage? A comparison that would be more valid IMHO would be a comparison between this 335i and the one 3-4 years ago.
Not particularly green, but better than in the past, I guess...?
I compared the BMW hybrid to BMW ICE car and it only improved by 24% which is not very impressive.
The Civic was compared to itself, 38% gain
The Fusion was compared to itself, 56% gain.
It is comparing like to like.
If you were not so hyper sensitive about BMW being something "special" you might have been able to see what I was saying.
In 2010 you could get a 34 mpg hybrid Camry rather than a 26 mpg ICE Camry. This represents a 31% improvement due to the hybrid.
However, this is a lousy hybrid. How do I know that, the proof is in the 2012 Camry.
The hybrid 2012 Camry gets 41 mpg rather than the 28 mpg of the ICE Camry. That is 46% better on top of the 7% that the ICE improved compared to 2010 (totaling 58% improvement from 2010 ICE to 2012 hybrid)
We will see the same thing from BMW in a couple of years. We will know the ActiveHybrid5 is poor when BMW delivers something much better in a couple of years. But no need to wait, ActiveHybrid5 is not very green.
