The Mercedes Benz F 700 was unveiled at the 2007 Frankfurt Motor Show, but was exhibited again at the Tokyo Motor Show a few weeks later. It’s what Mercedes Benz thinks a luxury long distance touring saloon of the future ideally should be, so we should expect it to point to the direction of the next generation S-Class.
Probably the first Mercedes Benz sedan with an A pillar window (hatchbacks like the A-Class already have an A pillar window if I’m not mistaken), the F 700 is certainly looks odd from the outside, with it’s strange curved side window profile, and its oversized front grille with vertical LED strip front headlamps. Mercedes Benz calls this design language “Aqua Dynamic”, which emulates the soft flowing forms of a fish.
But the interior looks fairly orthodox as far as luxury cruiser interiors go, designed to seat a driver and 3 passengers very comfortably. The front passenger seat can be put into relaxation mode – not for the front passenger of course as the seat has to be vacant for it to do this – but for the rear right passenger. The rear passenger seat situated behind the front passenger seat can even be turned around to face the rear of the car – Mercedes rather uncreatively calls this feature the REVERSE seat. He can have face to face conversations with the other rear passenger this way.
Despite the F 700 name, it does not indicate a 7 litre engine under the hood, or even the equivalent of a 7 litre engine. Instead, the engine used to power this concept is the Mercedes Benz DIESOTTO engine concept. This four cyclinder engine puts out the equivalent of a 3.5 litre normally aspirated V6 petrol or a 3.0 litre V6 turbodiesel in Mercedes terms. The name DIESOTTO seems to indicate something related to diesel, but the engine consumes petrol. This is just a guess but the word DIESOTTO is probably some combination of Diesel cycle combustion and Otto cycle combustion.
The DIESOTTO engine has 1.8 litres of displacement but puts out 238 horsepower with smoothness worthy of a luxury tourer thanks to a two-stage turbocharging system. Take-off is also assisted by a hybrid module, which uses a 15kW (20 horsepower) motor – this gives a total output of 258 horsepower and a maximum torque of about 400Nm. The F 700 can reach 100km/h in 7.5 seconds, up to a limited top speed of 200km/h. Fuel consumption is rated at 5.3 litres per 100km, and CO2 emissions is rated at 127g/km.
The engine works like a normal Otto cycle engine on starting and at full load, using spark ignition and the usual works. But at low and medium engine speeds, or generally partial load conditions the DIESOTTO engine uses something similiar to a Diesel cycle – controlled auto ignition or homogeneous combustion. I’ve previously blogged about homogeneous combustion here, so read up if you want to know more on that.
The F 700 at 5.18 meters is shorter than the current S-Class long wheel base, but it’s wheelbase is 3.45 meters, longer than the production model S-class by 28.5cm. Other technologies include PRE-SCAN suspension, which uses two laser sensors in the front headlamp units as “eyes”. These feed the car suspension system information on roadway conditions. This information helps the suspension hydraulic systems precisely calculate fluid flows and pressures for each single wheel, ensuring maximum comfort.

so its self ignited patrol engine in combination, fuel efficient and the leanest combustion, id say its a dynamic engine capable to suit variable type of combustion,
its an didication that these age of automotive really need at lest direct injection 4 stroker in their engine in the interest of tackling energy crisis,
i guess towards 2009 makers are moving towards that, some germans have it and japs did now,
Brand aside….I prefer the Nissan Intima to this. This just don’t look nice!
Paul, if you watch the video of How the F700 runs over the BUMP, you will get SURPRISE. Why? the car does Bumping UP or Down like cruising in the AIR!
LOL!
Sorry I meant It doesn’t BUMPING UP or DOWN! Got TYPO!
the Bose car suspension is also something like that. have you seen the Bose suspension videos?
Wow, that’s really amazing. Any Bose suspension that fits Persona?
This car looks real fancy. just have a look at the doors. Imagine you’re arriving to a celeb party with this. The door will open backwards and it does not stop opening until 90 deg angle.
Real classy!
Wow.. So hebat the engine technology… In Malaysia this car road tax will be cheap! Anyway the bose is famous for building audio system, the suspension is not like ordinary suspension… They use electromagnetic (Bose linear
electromagnetic motor) to control the damping valve inside the absorber, is something like Audi TT new suspension system…

this is one hell long machine… side parking needs two parking spaces… or three?
ferreris , american ford to name a few, readily will go direct injected for 2009,
still not to mention the reasonably priced car or peoples car, but its not possible,
so far fsi ,a-vtech seemed in its speciality, but…………
in the next year not too far, it might in vast market,
so maker should think ahead,,
Looks like the S-class put thru a furnace and it’s melting down. Hehe.
this is ugly
our future car will look like this??
ugly as hell….. a hint of MB future design?
the bose suspensions are really awesome,must be very expensive…this car will look nice in modern vampire movies..hehehe..

i-vtech I for honda direct injected,
a-vtech (port injected,,?)
——————
anyway i really hope local car maker is readily into this, -seriously insist-
Great insides, ugly exterior
The Benz’s next gen DNA. Maybe it will end as Maybach?
Woah, very nice looking car there, kinda reminds me of the Citroen C-Metisse. They should have chopped the butt right after the rear wheels though, now it’s sticking out obscenely.
its way too long like titanic when u round it. but its really cool. lil bit unique.
it looks more like a future CLS than a future S, as the CLS has already been on the road for a couple of years
There is a mass production car that uses direct injection!
Mazda have been selling their 2.4L turbo with direction injection for nearly 2 years now.
Come on, direct injection is not that far away from reality and you can forget about American dinosaur cars ever gonna improve.
not to mention this merc tech is a bit beyond,
and at our present there are cars out there is direct injected,
the situation is where there will the time port injection will be phasing out and be replaced with direct injector even in smaller displacement or cheaper car, generally in vast market,
and i bet towards 2009 theres is a signifacan change in automotive industry toward emission and efficency, without sacrificing the power needed,
I like to see that as well, as long as it saves fuel. I’m happy
