Cadillac XTS Virtual Dyno -ing was this afternoon’s XTS fun.<\/p>\n

I have been experimenting with the Virtual Dyno software<\/a> from Brad Barnhill.\u00a0 Since I had the Cadillac XTS out for a weekend test drive, courtesy of Crest Cadillac<\/a> of Plano, I did some instrumented tests on it.<\/p>\n

First, the XTS was hot after our morning out, and it is hot here in Texas.\u00a0 The 3.6L V6 was running intake temps up in the 150Fs.\u00a0\u00a0 On my supercharged Cadillac STS-V I would call that an intercooler cooling challenge, but on the normally aspirated 3.6L it is a normal sort of temperature.<\/p>\n

The XTS is advertised at 304 hp at the crank, so we were hoping to see around 240 whp, or hp at the wheels.\u00a0 Automatics are often characterized as having 20% drive train losses.<\/p>\n

The Cadillac XTS pulled through the heat and put down 233 whp in the max run.\u00a0 That either means the XTS has drivetrain losses of 23%, or it was hot today.\u00a0 We know I live at 600 feet above sea level and its hot here, so it is close enough to the expected 240 whp to say that the XTS is putting the rated power down.<\/p>\n

Since the XTS is new, Brad doesn’t have a file for it yet.\u00a0 I created an XML file for Virtual Dyno to use with the XTS:<\/p>\n

Cadillac XTS Virtual Dyno Summary<\/h2>\n

The 3.6L DOHC, VVT V6 in the Cadillac XTS is performing as expecting, and putting down the rated power.\u00a0\u00a0 It revs right up to 6,800+ rpm before shifting at wide open throttle, and is not pulling any punches with the transmission in sport mode.<\/p>\n","protected":false},"excerpt":{"rendered":"
