1981 Mercedes Auto 2000
http://www.whnet.com/4x4/81auto2000.html
1981 "Auto 2000" research car - Towards an economical, low-emission future. V8 petrol engine with cylinder shut-off and bi-turbo diesel engine. Pointing the way forward for aerodynamics. Despite its complicated wording, the project title nevertheless succeeded in firing the imagination: "Demonstration of automotive engineering research results in the form of integrated overall concepts for passenger car test models." This was how the Federal Ministry for Research and Technology worded the call it made to German car manufacturers in 1980 to devise proposals for the passenger cars of the future. The primary objective was a reduction in fuel consumption: the target limit was 9.5 litres per 100 kilometres for cars with a curb weight of between 1250 and 1700 kilograms and 11 litres per 100 kilometres for curb weights up to 2150 kilograms. The cars also had to be able to accommodate at least four persons and carry a payload of over 400 kilograms, all without compromising in any way in performance, comfort or range. Clear improvements were also expected in terms of service life, ease of repair, safety and environmental compatibility compared to series-production cars of that time. Manufacturers had until spring 1981 to prepare road-worthy prototypes of their visions for the future, which would then be unveiled to the public in September of the same year. The Federal Ministry for Research funded this ambitious project to the tune of around 110 million Deutschmarks, a figure which was then matched by the German automotive industry. Economy, preservation of resources, reduction of emissions - all challenges to mainly test the skills of drive system researchers. Mercedes-Benz soon had two new engine concepts ready to try out in the new "Auto 2000" research car. Despite being built around quite different technologies, the two powerplants still had one thing in common: their rated output of 110 kW/150 hp, which was deemed to be adequate at the time in view of the lightweight, streamlined body with its Cd value of just 0.28. The petrol engine designed for the research car was derived from a standard V8 powerplant with a displacement of 3.8 liters. What made the modified engine so special was its fuel consumption, which was significantly lower at partial throttle. The key to achieving this was an automatic cylinder shut-off system that temporarily shut down four of the eight combustion chambers whenever the extra power was surplus to requirements. The fact is that four cylinders operating at full load consume less fuel than twice as many cylinders operating at partial load, resulting in the fuel consumption figure for the Euromix driving cycle (urban, 90 km/h and 120 km/h) being reduced to just 9.3 liters per 100 kilometers. The bi-turbo diesel engine shown was a V6, also rated at 110 kW / 150 hp, and burnt only 7.5 liters per 100 kilometers driving at 120 km/h. It used a light-alloy V6 engine block with 3.3 liter displacement and two turbo chargers arranged in a two-stage configuration (Register-Turbo-Aufladung). As a third powerplant option, Daimler-Benz also installed a twinshaft gas turbine in the Auto 2000 - using all-ceramic rotors for the first time - which underwent thorough testing at temperatures of about 1250°C and speeds of up to 60,000 rpm. Also, integral seats for the driver and front passenger, with all the belt anchor mounts integrated on the seat itself, were tested in "Auto 2000", along with integral child restraint systems in the rear and pedestrian-friendly bumpers. The Research Car featured electronic driver information systems, a computer- controlled indicator system, and a driving program selector permitting control of engine and automatic transmission. A modified version of the "Anti-Block Braking System" (ABS) had been designed to prevent the drive wheels from spinning during acceleration on surfaces with poor traction. The Mercedes-Benz Auto 2000, presented in 1981, was created while Werner Breitschwerdt was head of Research & Development. Source: Daimler AG |

I've got a 1987 MB sales brochure in which this car is pictured. The section talked about how MB is innovating in fuel efficient and alternative fuel projects.
Interesting to note that this car shares many design elements with future models. I see a bit of 124 and 140 in there...also the precursor to the 15-hole wheel. Gas turbine, huh? Instead of smoking out tailgaters, you could just punch it and melt their bumper!

It reminds me of the 6000 SUX from Robocop.

Shutting of half the cylinders and running of four, reminds me that cadillac
had that engine that ran on four, six or eight cylinders. Don`t know what became of it. this thing looks like a hodge podge of different designs put together. the rear glass reminds me of the baracuda that had that long back glass. the front looks like the w124, and some how I can see the Citron in there also. The hood tipping sideways, the International Harvester trucks in the 50`s did that also. Charlie

It was another one of GM's monumental failures that even GM wanted to forget.

current honda V6s do the shutting down of 3 cylinders, as does a recent Hemi (not sure if they still do)
that car looks like a w124 limo hatchback |

[QUOTE=charmalu;2153471]Shutting of half the cylinders and running of four, reminds me that cadillac

[QUOTE] It was a disaster, primarily because the technology was too new for a reliable version to be built at an acceptable price point. Today you could probably build such a thing (and I guess some people are).

Its a four door hatchback...Looks like they took parts from the Mercedes Benz R129 front, a chrysler New york midsection, and a for mazda RX7 back end section, and put it together and bam, an ugly beast...

It certainly has some interesting looks..... I'd drive it. Imagine how people would stare! Especially with the turbine for a powerplant!

So what's the 0-60 time for the turbine engine...

Jay Leno is working on a turbine/jet car right now.....I believe as his mechanic put it: "it gets to 80 real quick".
