The Cadillac Sixteen is an expensive luxury concept available only in Test Drive Unlimited, but only if you download the DLC.
The average price for this car is $770,000.
The Cadillac Sixteen is a D-class luxury car that only appears in one color - jet black. It is powered by a 13600 cc 1000 bhp. V16 engine with a RWD drivetrain with a redline of 6500 rpm. The Sixteen has an impressive amount of power, however the handling is slightly below average, which, of course, is caused by the Sixteen's large size. It reaches 0-60 Mph/0-100 KPH in 5 seconds, and has a top speed of 186 MPH/300 KPH.
- Oddly, the Sixteens audio files seems to be copied off of the Edonis' files, possessing the same horn and engine sounds.
