LT1 Differences Across Various GM Models
Original question is here.
Kracka asked:
I am curious about simple, but possibly interesting question. The LT1 is now used in multiple models, the Corvette and Camaro. Are the actual engines identical in design and specs as they're built before getting prepared for installation (i.e. before manifolds, etc. are bolted on)? If they do differ, what differentiates the Corvette-specific LT1 from the others? While we are on the topic of the LT1, what was the reasoning behind the decision to bring back (or recycle, depending on how you want to look at it) the LT1 and LT4 engine designations. Thank you for your time and consideration!

Different Oil Needed for Street vs Track
Original question is here.
descartesfool asked:
What is the effect of changing from Dexos compliant 5W30 to Mobil1 15W50 for the track and back for road use? Some cars which are used on track a lot such as Porsches and GT-Rs recommend Mobil 1 0W40 for all uses, with no changes required when driving on track. Would this oil be fine for track and street use in the C7? What are the negative effects of leaving the 15W50 after track days and driving on the road, and at what temperatures is it an issue, hot or cold?

PDR Pre-Record Button
Original thread is here.
slickstick asked:
While the PDR is cool for the track, it would be nice if it had a street mode as well. It could be set to record constantly, and add a recording 'hotkey' to the infotainment home screen. If anything noteworthy happens on the streets, pushing the record button would instantly enter record mode, and with a configurable pre-record (ex: 30-60 seconds) would capture what happened prior to the button push.
Can this feature we added via software update? It seems very simple and straightforward to provide owners.

Drivetrain Efficiencies
Original thread is here.
vader86 asked:
I am certain that since automakers continually chase efficiency, that certainly modern drivetrains are a little better now than they were even in the 80s or 90s. My question is whether the powertrain efficiencies have been improved over C5-C7 to reduce frictional and inertial losses and by how much quantitatively?

Can "Performance Shift Active" Explained
Original question is here.
AllFlash asked:
Under certain conditions, accelerating ones Corvette will trigger 'Performance Shift Active' on Corvettes and a number of changes are observed, least of which is a delayed changing of gears in the A8 while acceleration or deceleration is present. Can you explain exactly what changes the car experiences, whether it be engine, transmission or suspension while 'Performance Shift Activated'...is active?
