Under the hood, you would have found GM’s 4.6-liter Northstar V8 unit, modified to produce roughly 400 horsepower, instead of its usual 300 hp. Cadillac did this without using any turbocharging or supercharging, which is fine, although the four-speed 4T80 automatic gearbox wasn’t exactly in-tune with the extra power.
Allen reportedly also considered other cars instead of the DeVille, like the Oldsmobile Aurora or the Lexus IS 300, but in the end, he settled on Cadillac’s two-tone beast, which ended up getting custom pistons and a 12.0 to 1 compression ratio, resulting in that extra 98 horsepower.
Other highlights included the carbon fiber rocker sills, quad-pipes at the rear, a narrowed rear fascia to accommodate US-only license plates, and a slightly wider brushed-aluminum grille.
The result was a better-looking car, simply put. Compared to a regular DeVille DTSi, this TAD variant looks more planted, more expensive and overall, more dynamic. It’s by no means a “driver’s car”, as Doug DeMuro recently found out, but it’s definitely better to drive than any lesser DeVille.
DeMuro concluded his review by saying just how special he considered this car to be and went as far as to confess that he’d like to purchase one, seen as how they’re extremely rare/exclusive.
We get why he’d want one. A rare car is a cool car, by most people’s definition. On top of that, the DeVille is mighty comfortable to cruise around in, so it should be relaxing to drive too.
