Roadster 2.0



  • edited November 2017
    Multiple Tesla’s were faster than the Bolt. It was a track record for production class. Tesla’s compete in production GT. Any experienced racer would know lap times are more about driver skill than the vehicle. Refuel TT is not a valid data set.

    TT Don't wast your time on dortor. He's a short and a lier, not a very good one too.

    And now we are ignoring data if if doesn’t forward our position

    200 kWh battery will not sweat that kind of power output. If there is a transmission (2-speed, etc) that will keep the motors at optimal RPM and prevent excessive heat. A 250+ mph Roadster has probably been vetted for high-speed operation. This is a purpose built car, not a family sedan. Stop assuming the worst.

    @dortor, the fact that they were running all night from the guy who drove the Drag Times guy is encouraging. But that wasn’t max power at high speeds for long times.

    It sure appears there is a paddle shifter on the steering colum implying more than just R & D. ;-)

    Here is to hoping they have some extra battery cooling tech so that you can take it to the track.

    A single lap around Laguna Seca would be depressing. Though, that said, a Formula 4 with slicks is going to eat your Porsche for lunch, at that track.

    I agree anything with slicks will eat a street car - I've driven on slicks at Laguna it's an awesome thing....I've raced/won and know what a real race car can do - I also know what most of the $250,000 sports cars can do (driven most of them) and they certainly don't neuter themselves after a few minutes at max performance.

    I just think a $250,000 sports car should be able to run laguna or any other track for a 25 minute Hooked on Driving HPDE session without going into limp mode...that is currently not the case for any car Tesla produces.

    The full EV radical being developed by Cameron and others is wicked fast and a serious race car - however they aren't managing battery thermals and don't have an 8 year unlimited mile warranty on the battery - they consider the battery a consumable like tires and are going for unrestricted performance ;-)

    There is actually _NO_ problem letting an LiON battery heat up during long high demand discharge cycles, you do however accelerate the batteries degradation and it very quickly loses capacity for the next charge cycle - but it will fully discharge at high rates and high temps - no problem....but you're not going to have it last very long.

    If you don't care about longevity you can run a LiON battery to virtually any temp. you want it will be fine for that charge've just lowered the max capacity for the next charge cycle.

    carlk don't be clueless! You would not expect the icenosaur to "lie" down and die after a hard smack down, would you? You have to expect some fight back. It must have hurt badly.

    inconel Didn't you see that I've been ignoring that perennial Tesla basher. The basher who first came to the X froum when the car was unveiled, and then to the 3 and now the Roadster forum. What good Roadsters folks have done to deserve this?

    The new roadster will probably weigh over 4000 pounds so it wont handle as well as lighter cars but will have more power in the straight sections of the track. I have never seen a current roadster on a track so I dont know if they die out after running at maximum speed or if the range is severly reduced.
    If range it shortened it would require having to trailer the csr to the track since you would be out of juice and not be able to recharge to drive home. A lot of people just want to be able to drive to the track and not have to have a truck and trailer to bring the car there. But if you can afford 250K for a track toy then money is probably no object. Also when the first rosdster came out a guy brought one to a car show. Initial accelation was fast but from 60 to 100 was slow according to someone who took it for a ride. Would a GT3 or McLaren be faster from 100 to 175 than a Roadster?

    The low COG will help a lot. People may not aware of it but even the Model S managed to have a slightly lower COG than the track ready 911 GT3. Its weight and those pretty weak tires hurt the cornering ability but the Roadster would have none of that. 4000 lb is not that bad it's about the same as some supercars, for example Lamborghini Aventador. From the video I also saw it's wearing beefy Pilot Sports CUP II tires. It indeed means serious business.

    One thing the Roadster has that no ICE cars could match is the torque steering mentioned in Elon's presentation. Some supercars have it but you can never match the quick response of individually controlled electric motors with brake or mechanical differential. I know there are some hybrids made partially for that reason but still you can't beat a full fledged electric car with that. I have a high confidence the Roadster will not disappoint in the handling department too.

    range don't care about - my GT3 gets like 8 mpg at the track - but I run it for 25-30 minutes solid - and when I was racing 90 minute enduros with one 5 min. pit stop

    the current Roadster does neuter itself after 1-2 laps - it's better than the Model S - but still not good enough to run flat out for 20 minutes - which would be about 8-9 laps @ laguna seca…

    and despite carlk's assertions I"m not bashing the roadster - I'm simply suggesting that a 1/4 million $$$ super char should be able to be driven hard for more than 2-3 minutes (current EV's don't last very long before reducing power) - I'm simply laying out an expectation that since we all know it won't meet it - relegates it to street only - and will NOT embarrass other high end supercars at the track if it can only do 1 or 2 laps.

    handling should be spectacular…

    GT3 and McLarens are certainly faster after 100 mph in acceleration - even P100D's start to lose badly once you're over 100 mph - fortunately that's not a requirement for most people and driving over 100 mph is a rare occurrence

    I'm simply stating my hope (and desire to purchase) a roadster, but not if it's only a drag racers - it needs some stamina

    Range be dammed in this application -and that NOT a requirement/expectation.

    will this car be able to complete 5 laps at a decent race track at full power without neutering itself, 10 laps? 15 laps?

    Most street sports cars aren't driven for more than 30 minutes in these applications because brakes, tires, cooling have their limits even in ICE cars, also most drivers can't maintain mental discipline for that long (it's stressful driving fast at your car's limits).

    race cars in enduro go longer, but they are street cars, and there is a driver change after 45 minutes. I don't expect _ANY_ street car to do an enduro of 90 minutes of maximum performance driving..and very few street sports cars would hold up to that sort of usage.

    But I routinely attend track days (have for 7-8 years) where we field 100-120 cars for a track day and they all can run full blast for 20-25 minute HPDE sessions - come in cool down and do it again for 4-6 sessions at a typical track day.

    Will the roadster be able to run with comparable 1/4 million $$$ supercars on track? Seems a reasonable requirement - and one or two laps doesn't count.

    clarification - when I do enduros I DO NOT use a street car - a full race prep'd race car is what is required for that - with full safety gear - again I don't expect Roadster 2.0 to match a purpose built race car

    but I'm looking forward to buying one if I can use it on the street or the track like any of it's ICE sport car cousins.

    I was very disappointed when the very first ICE sports cars were introduced in the early 1920s (if my memory serves me well, I am getting old...). Those gasoline cars should not have been called "sports" as I could not take them to jumping competition that I had been doing with my horses.
  • edited November -1
    I was really looking forward to buying that "sports" car if I could use it on the jumping tracks like any of the horses that car was advertised to replace because it was better.

    Lol...There is nothing sporty about running laps unless you're doing it in running shoes.
  • edited November 2017
    I hope they can make tires than can hold up at 250mph.

    Bugatti Veyron tyres are 17K!

    @calrk, disagree.

    I learned a lot at Laguna Seca.
