Tesla Announces Dual Motors, 'Autopilot' For the Model S 283

SchrodingerZ writes: Nine days after Elon Musk hinted about a new project, Tesla Motors has unveiled the P85D Sedan. This is Tesla's latest car design, capable of feats not yet seen in electric vehicles. The four door luxury car is able to go from zero to 60 miles per hour in a mere 3.2 seconds, an acceleration similar to the McLaren F1 super car. While the exterior remains the same build as the standard Model S, the interior will have a second motor in the front of the car to complement the rear motor. The D models will also have a slightly greater range of 275 miles on a single charge, 10 miles more than the 85 and P85 cars. Safety features have also been enhanced, adding "adaptive cruise control and the ability to read speed limit signs, stop itself if a crash is imminent, stay in its lane, and even park itself in a street spot or in your garage." Musk explains at the inaugural event, "this car is nuts. It's like taking off from a carrier deck. It's just bananas." The "D" version is available for the 60kWh, 80kWh, and P85 cars, and are expected to start shipping in December of this year.

    So, 0 to 60 miles in 3.2 seconds... a range of 275 miles... So, it has less than 15 seconds of autonomy.

    Let's hope it doesn't take much longer than that to recharge.

    This is how electric will win. Performance.
    When I was in High-school I raced RC cars for fun, and I remembered by gear head friends giving me crap about working on "Toy cars" until I challenged one of them to a drag race, against his real, full sized muscle car, and won hands down. The torque from an electric motor is just monstrous. So much so, that I suspect if they continue to build electric sports cars, the gforce alone will become a safety issue. My drag car would pull 100amps off the starting line and could melt battery cables, and the thing only weighed 2lbs. It'd be doing the scale equivalent of over 1000mph when I got to the end of the track. Yes, yes, I know at full scale wind resistance is different and such, but still. I had a hunk of carbon fiber doing 100mph in a few feet for Christs sake.

    The sorts of people that hate electric because it's a "hippie thing" will embrace it because the fact of the matter is that, in the end, it just performs better. Can't have hippies beating your Cudda with a Prius.

    • There is an electric race car that puts out something like 830 HP and 2950 ft. lbs. of torque. I can't even imagine what that kind of power feels like behind the wheel. Electric cars are exciting to gearheads like me who enjoy performance driving. I can't wait until they become more affordable.

Electric cars are exciting to gearheads like me who enjoy performance driving. I can't wait until they become more affordable.

        The well-known electric racing circuit is the Formula E [wikipedia.org] which uses pure electric race cars. Now, they only last about 10 minutes before drivers have to pit and switch cars, but that just adds a bit more excitement to the mix (how fast you can egress and get in now becomes important, just like how long you spend at pit spots in regular auto racing).

        Though, the other thing is just how quiet it is - yeah, I know modern race cars are actually getting a lot quieter to improve mileage (sound energy is wasted energy) and lengthen times between pit stops for refuelling.

        Heck, a lot are starting to experiment with hybrid technology for the same reason - pit stops cost time, and if you can go just as fast but use less fuel, then you have a big advantage by skipping a 30-second pit stop (plus having to actually drive through pit row - there's a 60mph speed limit that's strictly enforced. There's a special button on the wheel for this where it limits the max speed to that).

        Heck, Formula E has people driving in interesting ways - is it better to be slower and prolong your battery, or go quick and get a sufficient lead for the swap?

        And given the low end torque, skill becomes important because wheels that' slip, while impressive, are wasted energy that could be better spent moving.

      Let me add to your reasoning. This is the same argument as for the television in the late 1940s, or the VCR in my own lifetime.

      I remember many years ago walking out of a specialty store that sold VCR equipment. The prices were way high, and before I left I commented to the sales person that VCRs were a rich man's game. At that point, it was a true statement.

      The 5% who can afford these electric cars will fund the initial manufacturing. Infrastructure will grow. Costs will come down. Given the power electricity has, and the relative safety of supplying outlets and other infrastructure, even more people will see the advantages, be able to afford it and buy it, and so on, increasingly, until it is being massed produced at ordinary consumer prices. The US, for one, is slowly but surely going to change in the transportation area.

      I'm still waiting on range and charging time to make it worth my investment. With a range of 200 miles per full charge, this car would meet my daily needs 85% of the time. I'd still need something for road trips.

      The ironic thing is that even in rural Texas [1], even the coal rollers think that Teslas are extremely useful and hope that eventually the company would make a one ton pickup truck. It would make life nice for a number of reasons:

      1: A lot of ranch vehicles tend to go a long distance, but get parked near the same spot at night, so an electric charger is useful.

      2: Trucks need torque at 0RPM. Electric motors deliver here in spades.

      3: Welders and other tools are needed. Having a heavy duty inverter and the ability to use the battery bank for powering an air compressor would come quite handy.

      4: Electric motors need a lot less upkeep than a diesel engine. No pee cans, no DPFs, no EGR valves, air filters, oil filters, just very minimal maintenance required.

      5: They use no fuel when stopped/idling, other than to keep the vehicle electronics going and the climate control system.

      6: They are quiet.

      7: An electric motor can sit indefinitely without worry about fuel turning to sludge (in the case of gasoline) or getting algae in it (like diesel.)

      8: No exhaust.

      Electric cars are like solar. Both sides, be it the hippies or the banjo country types understand how useful the technology is or can be.

    • Ditto here. I've raced both electric and nitro RC cars for about 27 years, and I choose electric hands-down.

      That's not to say that each has pros and cons. Nitro cars tend to have impressive top speeds, and since they can make pit-stops to refuel, races can last as long as half an hour (I've seen some that last as much as an hour). Electrics have short range, and almost all races I've been in tend to last 5-10 minutes. I've never been in a race where pit-stops are made for battery changes, but I've seen

      • When I did the endurance stuff, I replaced my differential with a one-way diff. That way I could coast. It really depended on the track, but I had so much damned torqe I'd basically power out of the turn and then coast into the next. If it was a very long oval, this was less useful... but the idea was fresh when I tried it and people couldn't believe how few battery changes I'd have to make.

      Yeah, but does it have... soul. :D

      Seriously, I like the mechanical sound of a nice inline 6 or a V8 under the hood. I love the control of a manual transmission and clutch and how it engages the driver and makes him/her an essential part of the vehicle. Yes, dual-clutch autos are faster and electric cars are even faster but something is lost in the process and it's a shame. But, most people don't care about such things so electrics will be perfect for the masses just not for us "enthusiasts". Now get off m

      Bingo.

      I would modify your statement a bit though - because different people want different things out of cars. I know Prius and Leaf owners that are already sold on electric vehicles. Those vehicles are insufferable yawn-inducers, so I'll never be interested... but plenty of people already are.

      However, the Teslas (so far) are clearly drivers cars made for discerning buyers by real enthusiasts. I've taken a model S on a test drive and it was really magnificent.

  • Wouldn't say I'm an early adopter. I got mine in March. Still love it as much today as I did last week. Still an awesome car.

    Did I wish I waited a year? Well, maybe just a little. But I'm sure a year from now the Model S will have even more features.

    Perhaps the autopilot can be retrofitted into the currently on-the-road Model S. After all, the other upgrade over the last year have been available at a mild markup.

    As for the dual motors, pretty much the same thing.

    This really should have been included in the summary:

    Each of the three versions of the Model S will come as a D model. The price of the 60kWh battery model will go from $71,070 to $75,070 for the dual motor system. The 85 kWh car goes from $81,070 to $85,070, and the P85 jumps from $105,570 to $120,170.

    No indication in this article if you can get the adaptive cruise control and other fun high-tech add-ons that come with the "D" (dual motor) version without paying for the D upgrade.

      The answer is yes:

      Tesla's electric Model S has proven a very technically advanced car, except in regards to driver assistance systems. All that changes now, as Tesla Motors CEO Elon Musk announced at an event in Los Angeles that every car manufactured over the last two weeks comes with new sensor hardware to enable what he calls Autopilot capabilities.

      The event on Thursday night also included an announcement about the D option, an all-wheel-drive Model S with motors at the front and rear wheels.

      The Autopilot hardware includes forward-looking radar and camera, combined with all-around long-range ultrasonic sensors. A software update being sent out to cars as an over-the-air update will enable driver assistance features such as adaptive cruise control, lane-keeping assist and automated parking.

    And because it is an electric car, we get 73% of the purchase price back here (Netherlands), because of tax related stuff. So this car effectively costs a quarter of the listed price. Not bad.
    • That's crazy. I would have expected a cap on how much of a rebate you can get.

    • First, it's not a return, and second, how do you arrive at 73%?

      You pay no BPM. This is a tax on cars, which used to be 20-30% of the before-tax purchase price, now it's calculated based on a car's CO2 emissions, you pay something like â70 per gram of CO2. For typical cars, this still adds up to 20-30% of the purchase price.

      The Model 3 (nee model E) will only only be cheap if Tesla can get cheap batteries to power it. Tesla's plan for getting cheap batteries is to produce them at huge scale in their GigaFactory (tm). Therefore, don't hold your breath for cheap Teslas until after the GigaFactory (tm) is complete and functioning.

    60 mph is 26.8224 meters per second. At 3.2 seconds, that's 8.382 mps2 / gravity (9.8 mps2) = 0.85G. I'll bet it's even higher off the line.
