From my avatar, it's pretty obvious that i'm a BMW fan. I've been closely following the F10 from when the first prototypes were captured in photos (December '07) up to the very latest media review. Without having ever driven or even seen the car in person, i know quite a lot about it.
If i were to take the BMW passion out of me, and temporarily move it aside, and look at the F10 objectively, i would say the following things:
1. The car looks absolutely beautiful. From the proportions, to the surfacing, right through to the details contained in the tailights, the car's design has a timeless, pure and clear impression on the beholder. I know, just like in the E39 generation, people will look back on this design with great respect and admiration.
2. The car's engineering is class-leading. From the HUD, to the integral active steering, all the way through to the Efficient Dynamics technologies, every aspect of this car has been well thought through. You can tell that the engineers have strived for asolute perfection in every aspect of the vehicle.
3. The car's dynamics are class-leading. The technologies in place, such as the new multi-link front suspension, dynamic drive, the powerful drivetrain; endow the car with the best performance, handling, steering and ride balance in its class. The reviews will attest to this
4. The way in which the vehicle developed and constructed is very intelligent. One of the things i recalled during the E60 release in '03 was that they never mentioned anything about the commonalities and synergies shared with the E65 7er. This time, BMW has made the link with the F01 and F07 very clear. The benefits to the customer is that the technology available in the F10 has been refined and perfected in the F01 and F07. Most importantly, the sheer scale of commonality between the F01, F07, F10 and i would presume the F11, F12 and F13, means that BMW's Large Models Product Line would be very profitable.
Overall, i would say that the F10 is a home-run for BMW. It would simply be the best car in the segment if not the best car in the real-world.
As for the E-Klasse? Well, i would not be dissapointed if i ever owned this car. Having driven the E500 last month, i would say the following:
1. The styling is perfectly in-line with the Mercedes values. I don't find the design particularly exciting, and the interior looks as if it came from the 80s, but overall, this Merc perfectly conveys the themes of solidity, safety and quality. The car feels as if its been built like a bank vault- and thats what Mercedes has always been about.
2. The engineering greatly exemplifies the MB ethos of engineering excellence. It might not have the same level of gadgets as the BMW, but the when driving the car and using its controls, it feels as if the Mercedes also has been very well thouroughly engineered. Its amazing, the car feels so solid, as if its been made from the single billet of steel.
3. The ride and handling is close to perfection. You really need to experience the ride in this thing- it is just so smooth, almost as if you're on a plane. The steering as well, is very communicative with perfect weighting.
Overall, i was very impressed with the E-Klasse. I would have deemed it to be the best car in the segment, but i knew that BMW would come back with a better answer with the 5er.
