Watch a Hennessey Tahoe OutDrag a Widebody Hellcat by Sebastien Bell August 15, 2018 Share Comments If Richard Rawlings has taught us anything, it’s that the Hellcat is powerful enough to be considered a handful. Even still, it’s not so much of a handful that an 805 hp Tahoe can’t handle it. The other lesson we might take from Rawlings’ impromptu crash test is that all-wheel-drive makes acceleration easier. So it should hardly be a surprise that with two extra driven wheels and 98 more horsepower, the Tahoe beats the Hellcat to the line. And yet, looking at the full-size SUV, you can’t help but be amazed at how quick it is.
