In GTA San Andreas, the Emperor, based on an 1990-1993 Infiniti Q45, represents a then contemporary large four-door sedan, with a lean design and somewhat rounded profile.
In GTA IV and GTA V, the Emperor, given an Albany badge, is based on a '78 or '79 Cadillac Deville or Fleetwood, judging by the front bumper, with a flattened front end and no hood ornament. The greenhouse is closer to a 1980-1984 Deville/1980-1986 Fleetwood; the rear could also be from these cars since their trunks have more subtle creases (the Emperor has extremely subtle creases on the trunk). It features a "beater" version of the Emperor, with junky paint finishes, worn interiors, an occasionally missing quarter panel, damaged headlight, broken left indicator and old wheels and tires.
Acceleration and speed of GTA San Andreas' Emperor are somewhat disappointing, as are handling and braking. The engine sounds as though it is a large V6 or V8, but is apparently incapable of delivering substantial power to the bulky, rear-drive vehicle. Using the E-brake around corners almost guarantees fishtailing, making this car almost useless when driving at high speeds. It is, however, a sturdy vehicle with low chances of roll overs, and does a fairly good job of absorbing damage.
GTA IV's Emperor is powered by a low-output V8, coupled to a 5 speed gearbox in RWD configuration. Due to its weight and low-power engine, the Emperor is quite slow off the line, and its top speed of 140 km/h (87 mph) leaves much to be desired (while the beater Emperor can only reach 125 km/h (77 mph)). Its soft suspension often results in its rear swinging out of control and subtle fishtailing. Braking is very poor, and strangely, for a vehicle that's designed to be reminiscent of late 1970s/early 1980s cars, ABS is available, although not standard. Crash deformation is below average, and build quality is surprisingly low: as the Emperor cannot sustain much damage before failing or catching fire.
