  1. Drew Says:

    Kudos to the kids and Ford. Do we know how they addressed the issue of freezing temperatures?

  2. George Ricci Says:

    I suspect a version of the new twin turbo dual overhead cam engine in the CT6 will be used in the Corvette C8. Probability with different bore/stoke, rpm range, and power output.

  3. Don B. Says:

    Cadillac just blew up all the theories and rumors that nobody was developing a new engine.

  4. Lambo2015 Says:

    I thought the autonomous cameras detected heat images which would have detected this person even in pure darkness. Guess they will need to add that ability.

    The water conservation idea is great as long as you live in areas that do not see below freezing temps. I guess they could add a concentrated antifreeze to the reservoir via another container.

    The Cadillac engine looks good but service repairs shops might not think so.

  5. Kit Gerhart Says:

    #1 I’ve heard over the years, that it is not good to use straight water in windshield washers, even where it doesn’t get cold, because of algae growth. I’d think they might want to add methanol to the rain water for that reason, even in warm climate areas, and they would clearly need antifreeze of some type in cold areas.

  6. Norm T Says:

    Is Buick getting a subscription service? I loved to subscribe to the most reliable, mass produced brand!

  7. Chuck Grenci Says:

    Yes, the Uber autonomous vehicle, with advanced Lidar and other sensors, should have reacted better (than it did). Whether it could or would have prevented the death we’ll never know. And yes, the pedestrian was at fault.

    While the save-water solution would work, I don’t think it would be price feasible to install on vehicles. And while the water saved seems substantial, it is really only a drop in a bucket (sorry for the silly reference).

    The new Cadillac V-8′s look quite impressive; whether the V-Sport with 550 hp or the CT6 Sport with 500 hp, it is a nice bump in power. The new 10-speed is also going to be coupled with the new engines.

  8. Kit Gerhart Says:

    I think Cadillac should have saved the money spent on the new engine, and used Corvette/Camaro V-8′s in the C6, but the new engine should be impressive. I hope the new engine is better thought out, overall, than the Northstar. I’ve read and heard that a lot of Cadillacs from a few years ago have gone to junk yards early, because of major problems with the Northstar engines.

  9. motorman Says:

    i wonder if that new caddy engine could end up in the new mid engine corvette

  10. Lambo2015 Says:

    Cant wait to hear the est MPG of the new Cadillac engine. I assume they changed to turbo over the supercharger and reduced the engine size from the 6.2L to the 4.2L to improve fuel effeciency.
    Either way glad to hear that development of the V8 is not dead and continues to improve at GM.

  11. BobD Says:

    Kudos to the kids for the rain-reuse concept, but feel this was more of Ford trying to make a PR “feel good” move. As others have said, there will be freezing issues and straight water does not work very well on oily/bug splattered windshield. Also, I question the 20 liter/year usage number. I probably only go through 1/2 gallon per year of wiper fluid.

  12. Frederick Schmidt Says:

    Hooray for a new V8!! Cadillac is the US brand invested in both types of vehicles. Their new engine show V8′s still have a place in our cars. The contrast between Lincoln and Cadillac directions is huge. Cadillac shows direction and vitality, Lincoln shows the opposite. Lincoln has always seemed to be lacking. I used to a Ford fan and owned many of their cars starting with a 1966 comet caliente. Now I would only look if I wanted a pick up or a pony car. I hope Ford wakes up becomes a company with excitement.

  13. BobD Says:

    The Cadillac engine looks like a packaging marvel. But I have to wonder about the heat management of the twin turbos and catalytic converters located in the “hot-V”. How do you keep two cherry-red turbos from melting everything around them. Must have more sophisticated thermal blankets than the space shuttle. Bold move for GM.

  14. Kit Gerhart Says:

    I’ve read in Corvette forums about a possible, or likely 4 valve, DOHC turbo for the mid engine Corvette. I suspect this Cadillac engine would be it. If it does turn out to be Cadillac-specific, it would be the first brand-specific GM engine in a long time, probably since the Northstar. The Northstar was used in non-Cadillacs later in life, in Buick Lucerne, a Bonneville version, and maybe others, but was generally considered a Cadillac engine.

  15. BobK Says:

    I don’t see the quick conclusion to say the pedestrian was at fault. What I see from the video is a vehicle being driven(?) by a driver not paying any attention what so ever to the road. When someone hits a deer we don’t say it was the deer’s fault. We say it was the driver’s fault.

    I suspect in our headlong rush to get autonomous vehicles on the road, it is always going to be the fault of someone or thing other than the car.

  16. Kit Gerhart Says:

    I hope the former Viper plant museum ends up being open to the public. It would be worth a drive up there, from Indiana, where I spend summers. I’ve liked a lot of Chrysler concepts cars over the years, and it would be interesting to see them “in person.”

  17. Lisk Says:

    The Cadillac engine is cool but aside from a few diesels I’m not sure if any gasoline cars have a hot-V turbo system? Is the intercooler in the intake valley as well? If so can the liquid keep up? It’s impressive and I’m sure a variation will show up in the Corvette. That’s my guess as to why the turbos are packaged the way they are.

    The Corvette is most likely the only reason for this engine. MB, Audi, BMW, and Lexus are slowly phasing out V8′s and this engine will be lucky to go in maybe 6-8,000 CT6 annually?
    Corvette is the real reason for the engine.

    This wouldn’t be the first time; the LS-engine in the Corvette spawned many truck engine variation and the big daddy, the Viper, spawned the V10 that filled the wheel houses of a lot of Ram pickups.

    So far the Volt power train hasn’t had that kind of impact :)

  18. motorman Says:

    the number of caddys using this engine would not pay for the development costs so there has to be more uses for the engine

  19. Kit Gerhart Says:

    I didn’t realize it until checking, but the Lexus LS now uses a turbo V6, rather than a V8. You can get a turbo V8 in the big German sedans, but maybe not much longer.

  20. Lambo2015 Says:

    #13 I have to agree that keeping this engine cool is going to be a chore. Especially if its packaged into a mid-engine corvette. Every wiring connection and plastic piece is going to be a brittle as glass. To make matters worse converters typically get hotter after you shut the engine off when there is no airflow. Packaged close to two turbos and surrounded by engine seems like a heat management nightmare.

  21. Roger Blose Says:

    The Cadillac engine is so packed with exterior plumbing that to fix a leaking valve cover gasket would be a disaster. And all of that heat on top of the motor and engine compartment will be yet another GM engineering problem. Hood re-paints anyone?

  22. Lambo2015 Says:

    Another crazy thing about that cadillac engine is if you pause the pics provided they routed the dipstick tube in front of the drive accessories.

  23. G.A.Branigan Says:

    If caddie detuned that new v8 a bit,it would make a great engine option in the 1500 series of pickups. 550hp,over 600ft.lbs. of twist.Say,425hp,550 ft lbs of torque through the new 10 spd.

    @ Sean: Any ideas of the rpm range on the new caddie engine? Where it makes peak hp,and peak trq?

  24. Steve W Says:

    Sean, when the Uber accident was first announced you said you needed to wait for an investigation but you felt anti AV people would jump on this. I am not anti AV but posted immediately that it could only be either faulty radar or a monitor/ driver error. I’m glad you mentioned today it was Uber’s mistake. I’m surprised that you really couldn’t see the obvious and used this as an editorial platform to put down people against AV’s.Frankly if AV’s do gain momentum in sales manufacturers will only be shooting themselves in the foot as the AV buyer will tend to look at their vehicle as an appliance and not replace them until the wheels fall off!

  25. Chuck Grenci Says:

    Here’s the spec’s on the new Caddy 4.2:

  26. Frederick Schmidt Says:

    23 good points. The auto makers would rather we never own only lease cars. Get people to budget so much per month and pay that for as long as they drive or be driven. I own and keep my cars, the last was 16 years with a 2000 Lexus Rx. But I think less and less people will do that as they tend not to value the pride of ownership and take care of and keep nice a vehicle. Once the shine is gone or the lease is done, time to move to the next shiny new car. Difference between my age group 68 and younger people. The younger people are their target market.

  27. Frederick Schmidt Says:

    meant 24 Steve not 23

  28. motorman Says:

    GM likes push rods in the trucks because they are a lot cheaper to build than a twin turbo dual overhead cam engine. ford may sell more trucks than chevy but they are not making the profit GM is on their trucks as their stock prices show

  29. G.A.Branigan Says:

    @ Motorman:

    I think sooner rather than later,GM is going to have to offer a boosted engine besides a diesel,in the 1500 series lineup.Jmho…

    @ Chuck G: Excellent link,thank you.It answered all my questions.

  30. Ukendoit Says:

    I agree with Sean’s assessment, that while the pedestrian was clearly at fault, jaywalking in the only dark section of the street without even looking up, the vehicle should have detected her. Isn’t Volvo’s own crash avoidance system from years ago supposed to stop before hitting a pedestrian? (Except for salesmen who have people run into them with vehicles that don’t have the sensors.) Did the Uber system disable the Volvo system?
    If you pause the video and advance it slowly until you can actually see the pedestrian, then hit play, I think I would have hit her too in that quick moment!

  31. Todd T Says:

    #25 The ship has sailed on the majority of consumers in the US seeing cars as an appliance. But, just like appliances, people like new ones. So, manufactures have little to fear, how many refrigerators, washers/dryers, and dishwashers are replaced before the one they have is worn out?

    The autonomous tech failed in the Uber car, there is simply no other way to say it. The situation of this accident is a prime example of a situation where the promise of autonomous tech was supposed to be BETTER than a human driver. And clearly the human driver “back up” failed too, as his eyes were NOT on the road. This accident is a litigator’s wet dream.

  32. Todd T Says:

    Above post was supposed to be #24

  33. Lambo2015 Says:

    What I’m really surprised is most bikes have reflectors and not even a reflector can be seen prior to the whole image of the pedestrian and the bike appear in the headlights.

  34. Kit Gerhart Says:

    Maybe the autonomous system should have “seen” the pedestrian and bike before the human driver, even an attentive driver. I think my 2017 Prius would do something, either brake or beep in a situation like that.

    29 In the latest CR tests, the F150 with the 2.7 turbo and 10-speed auto worked well, getting 19 mpg overall, compared to 16 mpg for the Silverado with a 5.3 and 6-speed. Also, the Ford was a little quicker in most acceleration tests, the notable exception being 45-65 mph, where the Chevy took 3.7 seconds, to the Ford’s 4.5 seconds. That looks like turbo lag, or the Ford’s transmission is slow to kick down. I’m pretty sure they “just floor it” for that test, with the transmission in whatever gear it would be in at a steady speed of 45.

    The bottom line is that, overall, by the numbers, the Ford 2.7 turbo performs better than the Chevy 5.3 V8. Still, if I were buying a truck for actual work, intending to keep it a long time, I’d rather take my chances with the much simpler engine in the Chevy. Also, maybe the Chevy would match the Ford in acceleration and mpg, just by using the 10-speed instead of 6-speed, without the turbochargers and extra camshafts.

  35. rick Says:

    kids & ford recycling rain water whats done in temps below freezing? what about legionnaires disease?

  36. Kit Gerhart Says:

    35 Add methanol

  37. Frederick Schmidt Says:

    The students and their idea show me that will have new idea and follow through people for the future. Small ideas like this lead to features on car like intermittent wipers,central locking system and collision air bags. We need more engineers and scientists with smarts minds. They deserve much praise.

  38. Bob Wilson Says:

    Contributing causes:
    1) pedestrian crossing in dark stretch of road wearing Ninja black top and blue jeans. Her white tennis shoes were first spotted.
    2) bicycle needs reflective tape around the tubes to improve spotting at night and active, LED lights after dark.
    3) XC90 driving on low beams faster than the headlights illuminated (i.e., over driving the lights.) IIHS list the headlights as “Marginal.”
    4) Tempe street lights make islands of light instead of extending further around the area.
    5) Pedestrian and driver were inattentive.

    We still need to see the final NTSB report since it will also include the sensors and algorithms. Musk has already said LIDAR is a dead end and I agree. But it is likely these are not IR sensitive cameras but they might have other problems dealing with hot exhaust and radiators.

  39. Kit Gerhart Says:

    38 Good analysis, IMHO. Still, as an habitual jaywalker, I find the victim mostly responsible for what happened. When I jaywalk, I make it a point that drivers will not have to do anything to avoid hitting me. When I am driving, I hope for the same from pedestrians.

  40. Kit Gerhart Says:

    After all if this discussion, I assume that the Volvo’s headlights were on low beam, not “parking lights ” if the lights were not on, that would change things completely, re. the woman’s seeing the approaching vehicle.

  41. BobD Says:

    Does the Cadillac have a dry sump? Why would it take 10 quarts of oil?

  42. Len Simpson Says:

    Since leaf was mentioned again today—–battery—648# of expensive dead weight w/a limited life makes no sense at all. I’m waiting for the 48v version w/run as needed small eng/gen. uses gas, not charging stations—-KISS KISS KISS !

  43. Kit Gerhart Says:

    48 volt “mild hybrids” are becoming widespread, with a number of car companies. The main source of propulsion is the regular ICE.

  44. Lambo2015 Says:

    Hybrids make the most sense right now until a wide spread charging infrastructure is in place and quick charging is available. It resolves the range anxiety and provides some of the benefits of an EV. Yeah it sucks to have the complexity of two systems for propulsion and the packaging and weight disadvantages of both but I just dont see EV’s being embraced until Evs can compete with ICE cars for range, charging, and price. Today they do not. Few people can afford an EV for just local driving with no plans to ever take it more than 100 miles from home. And thats what you would be buying with an EV today.

  45. Kit Gerhart Says:

    In spite of the complexity, many, or most hybrids are very reliable. Also, Toyota and Ford, and maybe some other hybrids are very simple, mechanically, with no friction elements.

    Plug-in hybrids, like Prius Prime and Volt can be a good option for those with fairly short commutes, and a place to plug in at home.

  46. Ctech Says:

    The new Cadillac engine is very similar in design to BMW’s 4.4L twin turbo V8. The BMW twin-turbo V8 had a number of teething problems upon introduction. Some of these engines had premature valve seal failures (heat hardened them and oil leaked into the combustion chambers causing excessive oil comsuption), oil line failures, coolant line failures (BMW fitted a separate cooling system for the intercoolers with its own pump), among other issues. Hopefully Cadillac has learned from BMW and has corrected these potential pitfalls. Otherwise warranty costs are going to be exorbitant. I leave it up to you to Google BMW V8 twin turbo problems.

  47. Terry Quinn Says:

    I copied the video of the Uber accident, and put it in my software to get some timings. From the first frame where you could see any part of the victim’s feet, was 1.4 seconds before impact. Watching the video just staring at the screen, I could clearly see the lady and stop the video by hitting a space bar on my computer at about 0.7 of a second after the first view of the foot came up, That would be reaction time. That leaves another 0.7 of a second to hit the brakes and/or swerve left. Furthermore, I believe that you could probably see out of the car better if you were sitting in the car than what the video shows. Overall, I don’t buy the comment by the Tempe Police Chief that this accident was unavoidable. I think that an alert human could have missed her.
