Tesla did a 7:23 in a heavily modified testing vehicle that has big extra air intakes for cooling, racing slicks, a massive rear diffuser, bigger spoiler, and is believed to have 3 engines.

For comparison, a front-wheel-drive stock Renault Megane RS does 7:40. Mercedes did 7:25 in a stock 4-door coupe last year, the AMG GT 63S. The stock supercars are down below the 7:00 mark mostly.

In the non-stock category, the record is 5:19 by one of Porsche's modified LMP1 cars.

If you look up how a stall speed converter works, you'll see that an automatic transmission delivers torque at a non-zero engine RPM even if the wheels are at zero RPM. The lowest you will go on the Duramax is around 1000 RPM, where you get 600 Nm torque.
