What happened to the work on this concept engine? Was the project scrapped by GM? 750HP? holy...
The Northstar was always slated to be killed off around '10 once the DTS went out of production. Honestly they're a problem-prone engine between the head sealing issues and oil leaks. At this point they've been around almost 20 years, and the R&D has to be about 25 years old. A lot has changed since then and my guess is GM did not feel it could be competitive to other luxury makes high end V8s. Perhaps there were limits in the design that would prevent now common additions such as DI, electronic lift control (think VTEC or VANOS and the like), and super/turbo charging (the blown XLR- and STS-V's were limited production, hand built engines and had to be very costly).what where the newer problems with the newer northstars that made them scrap them ?
can't be anyworst the the HG issue with the erly 90s threw 2005 can it ?
Eh, that's debatable to me as an engineer. Anything done to address the inherent issues of the Northstar would just be a bandage, and GM sorely needs to continue to move away from the "bandage" logic of fixing things and pursue robust designs.And the Northstar has an exhaust note that makes anyone's ears tune in as the vehicle drives by- There are issues with the Northstar and always have been, but nothing that could not be improved/fixed.
