Editing GM High Feature engine (section)

==Fourth generation==
Starting with the 2016 Cadillac models, a new generation of High Feature V6s were developed.<ref>{{cite web|url=http://media.cadillac.com/media/us/en/cadillac/news.detail.html/content/Pages/news/us/en/2015/mar/0320-cadillac/0320-cadillac-36l.html|access-date=5 April 2015|title=All-New, Advanced 3.6L V-6 to Drive Cadillac CT6|date=20 March 2015}}</ref> These new engines have redesigned block architectures with bore centers increased from {{convert|103|mm|in|abbr=on|sigfig=4}} on prior HFV6 engines to {{convert|106|mm|in|abbr=on|sigfig=4}} and a redesigned cooling system to target the hottest areas while also facilitating faster warm-up. They also incorporate engine start-stop technology, cylinder-deactivation, 2-stage oil pumps, and updated variable valve timing featuring intermediate park technology for late-intake valve closure. Both engines debuted in the 2016 [[Cadillac CT6]].<ref>{{cite web|title=Cadillac Next-Gen V-6 Engines Led by 3.0L Twin Turbo|url=http://media.gm.com/media/us/en/gm/news.detail.html/content/Pages/news/us/en/2015/mar/0320-cadillac/0320-cadillac-twin-turbo.html|website=GM Media USA|date=20 March 2015|publisher=GM|access-date=20 March 2015}}</ref>

=== 3.6 L ===
==== LGX ====
Along with the increased bore spacing, the new 3.6 L DI V6 has larger bores than before, growing from {{convert|94|mm|in|abbr=on|sigfig=4}} to {{convert|95|mm|in|abbr=on|sigfig=4}} with the same {{convert|85.8|mm|in|abbr=on|sigfig=4}} stroke as the 3.0L LGW, for a displacement of {{convert|3649|cc|L|1|order=flip|abbr=on}}. Intake and exhaust valves are also increased in size along with other changes to the cylinder head.<ref>{{cite web|title=All-New, Advanced 3.6L V-6 to Drive Cadillac CT6|url=http://media.cadillac.com/media/us/en/cadillac/news.detail.html/content/Pages/news/us/en/2015/mar/0320-cadillac/0320-cadillac-36l.html|website=Cadillac Media USA|date=20 March 2015|publisher=Cadillac Media USA|access-date=20 March 2015}}</ref> The only part shared with the prior generation is the hydraulic lash adjusters in the valvetrain.<ref name="eward">{{cite web | url=https://www.wardsauto.com/technology/gm-powertrain-shows-love-6-pack | title=GM Powertrain Shows Love for 6-Pack | date=9 November 2015 }}</ref> The LGX was benchmarked against the 3.7L [[Nissan VQ engine#VQ37VHR|VQ37VHR]] of the 2015 Infiniti Q40.<ref name="eward"/> Compression ratio is 11.5:1 and maximum engine speed is 7200 RPM.

Compared to GM's LFX/LFY 3.6 L engine, the LGX features active fuel management, [[Noise, vibration, and harshness|NVH]] enhancements and slightly more torque.<ref>{{cite web |last1=Albrecht |first1=Tom |title=Buyers Don’t Seem To Care That New Buick Enclave Uses Last-Gen Engine |url=https://gmauthority.com/blog/2018/09/buyers-dont-care-that-new-buick-enclave-uses-last-gen-engine/ |access-date=27 March 2024}}</ref>
