Re: 2010-2013 "Luxury" package and "Premium" package differences...?
The 2012 Cadillac CTS is a five-passenger midsize luxury sedan that is available in four trim levels: 3.0 base, 3.0 Luxury, 3.6 Performance and 3.6 Premium. The high-performance CTS-V is reviewed separately, as are the CTS Coupe and Sport Wagon.
The 3.0 base comes standard with 17-inch alloy wheels, automatic headlights, heated mirrors, keyless entry, cruise control, dual-zone automatic climate control, an eight-way power driver seat, leatherette premium vinyl upholstery, a tilt-and-telescoping steering wheel, an auto-dimming rearview mirror, OnStar, Bluetooth and an eight-speaker Bose sound system with a CD player and satellite radio. The 3.0 Luxury adds remote ignition, additional sound insulation, automatic wipers, a rearview camera, driver memory functions, heated eight-way power front seats (with two-way lumbar adjustment), leather upholstery, a wood-trimmed steering wheel, interior accent lighting, and a six-CD changer.
The optional 18-inch All-Season Tire Performance package adds 18-inch wheels, a sport-tuned suspension (dubbed FE2), xenon headlights and foglights. The CTS Touring package is similar but also adds a sport grille and special interior trim.
The 3.6 Performance trim adds to the 3.0 base equipment a more powerful engine, the All-Season Tire Performance package, remote ignition, heated eight-way power front seats, driver memory functions and a 10-speaker Bose surround-sound audio system with a CD player, digital music storage and an iPod/USB audio interface. The Luxury Level Two package adds the rest of the 3.0 Luxury's extra equipment, plus rear parking sensors, heated and ventilated front seats, a split-folding rear seat, a power-adjustable steering wheel, keyless ignition/entry and a cabin deodorizer.
The 3.6 Premium includes all the above equipment, but adds a panoramic sunroof (optional on all other trims), a heated steering wheel, a navigation system (optional on all but the base model) with a pop-up touchscreen interface, and real-time traffic and weather.
As its name suggests, the 19-inch Summer Tire Performance package adds 19-inch wheels, summer tires, an even sportier suspension (FE3), a limited-slip differential, upgraded brakes and shift paddles. A CTS Touring package for the 3.6 is also offered but in this case also includes Recaro front seats.
