C7 test fleet completed 1,000,000 miles of real world testing last week....
Attended the quality seminar conducted by Steve Grilli. He is in charge of the quality program at the Bowling Green plant. Couple of things from the notes I made out from that seminar:
* Test fleet is about 202 cars * They sub-contract the testing of cars * 1,000,000 mile testing was completed last week (about 5,000 per car if my math in my head is correct) * Blue car that was wrecked in AZ (the one on it's side on the rocks) has been repaired (body panels and frame) and put back into service (testing). Apparently, if I got it right, it went into a 6' drop off on the edge of the road, skidded on it side for about 50' before coming onto the rocks where it was photographed for the internet. Driver got out and walked away. * The cyber grey C7 t-boned by a Lincoln Town car in MI is waiting for body parts (fender, door, quarter panel) and will be going back into testing service. Lincoln driver didn't see the C7 and was destroyed in the front end. The C7 driver got out and walked away. No frame damage. * Production has started and they are at about 20 cars per day. Their goal at full production is "18.5 jobs per hour" which equals 135 cars per day. |
All those cars and all of those miles and still no sightings in Georgia :( lol

Thanks to the OP for the update and the details on the accidents/repairs. :thumbs: Some issues won't show up until individual units actually have fairly high miles put on under normal driving conditions and these oddities won't show up except under the right environmental conditions but usually they can be addressed through calibration updates. But this standard testing should result in early production that is far closer to perfect than those older new vehicles we all remember with fond nostalgia through our rose colored glasses that filter out unpleasant memories of the problems that were so common in early production vehicles. |

Now that is impressive! Did it occur on wet streets? |
A 5K mile test will not reveal anything but the most obvious problems. Many engineering issues are not mileage dependent but time dependent. A car can sit in storage for 5 years and when it is taken out a number of problems will surface due to oxidation of metal contacts as well as deterioration of petrochemical plastic parts. Long term testing requires time.

I wonder if all cars were treated the same. Such as one car being mostly highway driven while another car sticking mainly to city driving. Or even one car being the "beater" car while another never see's redline. GM can only do so much to see what kind of unseen issues pop up. Isn't this million mile testing somewhat new? First time I heard GM doing it was with the cruze. Nonetheless, I like the GM has done this but every car maker has recalls and TSB's. Its only a matter of time before we find out the "hopefully few" quirks the C7 has.

I'm sure GM bypassed their standard new car testing and rushed the C7 to market. The myriad problems that they are going to experience should start very soon now. If they wanted to effectively test the car, they should have had a fleet of 100 cars complete 100k miles each over a three year period.
S. So, three years of captured test fleet experience instead of three months? Interesting idea. I suspect those buyers who wait until the second or third year of production to buy new consider the buyers of the first model year production to be the testers. Laborsmith |

Now a days they do so much computer simulation and bench testing, they don't need as many miles on the road. The road miles just verify what the computers are saying from real world experience.
Of course, there is nothing like real world driving. But if you want to know why cars have been getting more and more reliable over the years, a lot of it has to do with computer simulations. |

Accelerated deterioration tests would be made on plastic, "rubber", metal parts on an individual basis. Also there would be some tests on a jig to simulate many miles of driving on rough roads to test the suspension and friction points in the assembly. This is not the only testing, it is part of the testing. It would also help them with the early at delivery kind of problems that J.D. Powers surveys. |
135 cars a day, thats ridiculous. Wonder why base price is 51k if they sell all of these, Corvettes will be everywhere in a year. Just like usual. These will be a dime a dozen next year at this time.

Is this a serious statement that you believe to be viable?

I read it in response to other guy three times...I had a tough time determining. Coupled with the other guy I quoted, I am thinkin...man, its a full moon on the forum, the crazy is comin out!
