2010 Cadillac STS: What's New, Specs & Features
Last updated August 4, 2026

The biggest change for the 2010 Cadillac STS is the loss of the STS-V trim. The remaining sedan is largely a carryover, with existing option packages reorganized as named trim levels and alloy wheels made standard.
About the 2010 Cadillac STS
1st and only STS generation (2005-2011), late-cycle year and third model year after the 2008 exterior and technology update
Cadillac positioned the STS as a midsize luxury performance sedan that balanced precise handling with a quiet, comfortable cabin. It sat between the smaller, more sport-focused CTS and the larger, softer-riding DTS. Its rear-drive-based layout, AWD configurations, strong V6 and V8 engines, roomy five-passenger interior, leather seating, and parking technology distinguished it from traditional front-wheel-drive luxury sedans.
Cadillac positioned the 2010 STS as a luxury performance sedan with a quiet cabin and composed road manners. Across the V6 and V8 lineup, notable features include leather upholstery, eight-way power front seats, Bose audio, dual-zone automatic climate control, keyless starting, and rear parking assistance.
