Lamborghini isn't presenting anything at the Detroit Auto Show because it doesn't even have a stand. But that doesn't mean that the Sant' Agata company had nothing to say. CEO Stephan Winkelmann and head of R&D Maurizio Reggiani spoke briefly about the Murciélago successor at a Sunday evening event outside of Cobo Hall, putting together a few more pieces of the Lamborghini 834 – otherwise known as the car many assume will be called the Aventador. Winkelmann said he wants it to be "the trendsetter of the next decade." The main points:
  • Cues: the 834 will have all the traditional modern Lamborghini cues, meaning all-wheel drive, scissor doors and prominent air intakes. Winkelmann said it would be revolutionary but recognizable, and that its inspiration has come from the military (not unlike the military-aircraft inspired Reventon)
  • Chassis: "Stiffness and lightness are the words to remember," said Winkelmann, and the company has planted its flag on the battleground known as "power-to-weight." The body-in-white is 229 kilograms, torsional stiffness is 35,000 Newton-Meters/degree and it has been homologated worldwide already. The entire monocoque cell is carbon fiber – the tub is a Lamborghini-developed process patented by the company as RTM (Resin Transfer Molded) Lambo, a slightly different process than standard RTM, the A- and B-Pillars and rocker panels are braided carbon fiber, and the roof is prepreg carbon fiber. The RTM Lambo process has been developed in conjunction with its work with Boeing and the University of Washington.
  • Engine: The new 6.5-liter V12 has 18 percent more power but emits 20 percent less CO2 – 398 g/km – than the 6.5-liter V12 in the now-discontinued Murciélago. It develops 700 horsepower at 8,450 rpm and 509 pound-feet at 5,500 rpm; although displacement is the same, the bore and stroke have been changed to provide better acceleration and smoother, more elastic power delivery in stop-and-go traffic.
  • Transmission: The 834 uses a seven-speed, single-clutch transmission developed and patented by Lamborghini as ISR (Independent Shifting Rod) and built by Graziano. A single clutch was chosen because it is 20 kilograms lighter than a dual clutch and, said Reggiani, "You have to have the drop in torque so you feel like you're shifting, to give the emotion." There will be five shift modes: Auto, Auto Strada ('strada' being for comfort), Strada, Sport and Corsa. The gearbox's syncros can disengage one gear as they're engaging the next, so shift times in Corsa will be 50 milliseconds (Formula 1 is about 40 ms), 150 ms in Sport, and 300 ms in Auto Strada.
  • Suspension: According to Lamborghini, the 834 will mark the first time a pushrod suspension with horizontal dampers appears on a production car. The setup will keep the wheel in perfect alignment throughout the range of suspension travel.
  • Brakes: There will be 400 mm carbon discs up front, 380 mm in back, and it will have an electronic parking brake.
  • Interior: There will, of course, be improved roominess all around, the driving position is now dead ahead and not skewed to the right, and the dash cluster is a single, large TFT screen.
  • Safety: The 834 will have passive pedestrian protection, four front airbags and two side airbags
One final note: Communications director Raffaello Porro confirmed that the company is still debating making both the Sesto Elemento and the Estoque. The Estoque is the natural way for the brand to grow (not an SUV), but if the Sesto Elemento is made it won't be homologated. A decision on the Sesto Elemento is expected in the first quarter of this year, while a decision on a third model will be made in the next 12 months.

      Awesome looking car with some very promising numbers.

      Expectations for this car are extremely high and with Audi at the helm, I think they will do better than just succeed. Can't wait for the road tests!

      What a shame, it doesn't mention what kind of radio it is going to have?
        • 4 Years Ago
        You have to learn to read. Can't you see that it has a 6.5l radio system?

      This transmission confuses me.
        • 4 Years Ago
        How so? There is a conventional dry clutch, there are 7 forward speeds.
        The 'big' advantage is that sequential gears do not have to be operated by the same selector fork, and therefore you can temporally overlap things that you could not before.

        I think Ferrari did exactly something like this 3-5 years ago, just not with all their gears. 1-3 was one pair, 2-4 was another, but 5-6 was retained (since they are very close together there was little time advantage to having an overlapping shift process)
        In Ferrari's case [up-shifting], 2nd gear starts to engage before 1st is fully released, the 2nd gear carbon synchronizer is up to maximum temperature (and coefficient of friction) and therefore can decelerate the clutch as quickly as possible, saving the maximum amount of time.

        Now you don't always have to operate this way, you can have the transmission operate purely sequentially: open clutch, release gear, select new gear, close clutch (see the mode where shifts take 300 milliseconds)

        Lamborghini is probably using: R-2, 1-3, 4-6, 5-7 as their design.

        What about the regular manual transmission? It makes me so sad to see companies dropping regular 6-speeds.

      I am literally salivating over the monitor. It's not every day San't Agata releases a new car. However, they have to work on the names. Diablo was the epitome of coolness. Murcielago has a certain Batman connotation to is. Aventador might be thought of as *he who farts* in Spanish.
      • 4 Years Ago
      I thought F1 cars shifted in something more like 15 or 16 miliseconds. I guess Steve Matchet was wrong. (I'm not quite sure if I spelled his name correctly.)
      • 4 Years Ago
      I can't wait to see this car racing in the FIA GT1 Series. It already looks pretty aggressive so I can't even imagine what it will look like in full race prep.
        • 4 Years Ago
        It will be a GT1?
        • 4 Years Ago
        Yes, It will replacement the current Murcielago LP670 R-SV.

      "first time a pushrod suspension with horizontal dampers appears on a production car."

      um i could be mistaken but production Ford GT did this in 2005
        • 4 Years Ago
        The Ford GT did not use inboard dampers and Lamborghini probably means not a limited production vehicle, because the Porsche Carrera GT had inboard dampers.

      I still laugh at "passive pedestrian protection" One of these days, we are going to need "Passive Aggressive Pedestrian Protection"
      • 4 Years Ago
      Why don't they just show it already?
      • 4 Years Ago
      WTH autoblog guys? You guys never took Engrish classes?

      "(not unlike the military-aircraft inspired Reventon)" -

      take the double negatives out and leave it as "LIKE THE military-aircraft inspired Reventon"

        • 4 Years Ago
        Sorry, but there is nothing wrong with saying "not unlike". It's perfectly acceptable grammar.
      • 4 Years Ago
      They are using homologated (the first time) in a way I am not familiar with. There's no way a vehicle can be "homologated worldwide" before a single copy is sold and delivered to the public.

      As to the rest of it, it sounds like a technological tour de force. But it also doesn't sound like a Lamborghini in spirit. I guess I shouldn't be too surprised that the company would change direction when they are under German ownership instead of the traditional Italian.
