Introduction

The STS-V premiered with a 0-60 mph (97 km/h) acceleration time of 4.6 seconds and a 12.9 second quarter mile time.[1] It was introduced at the 2005 Detroit Auto Show, and was available for sale in late 2005.

Specifications

The STS-V uses a supercharged 4.4 L version of the Northstar V8, producing 469 hp (350 kW) and 439 lb⋅ft (595 N⋅m). This engine is mated to a driver-adjustable automatic transmission with two shifting modes, larger brakes by Brembo, larger 10 spoke alloy wheels (18"x8.5" front, 19"x9.5" rear), Pirelli run-flat tires, a faster steering ratio, and a stiffer suspension than the standard STS. The engine block and cylinder heads are aluminum, the camshafts are cast iron, and the crankshaft is forged steel. Suspension is fully independent and there are four settings for the traction control system and stability control. Also, different from the standard STS, the STS-V has a cooler for the rear differential oil located on the underside of the car behind the 3rd member.

Appearance

The STS-V's primary visual difference from the standard STS was a wire mesh grille and a 'power-dome' hood as well as six lug wheels normally seen only on trucks and pickups.

In addition to the grille, the front differences include the bumper, the fog light and turning signal cluster, and the hood which is slightly domed to fit over the supercharger.

In the rear, the bumper is different from the standard STS and includes a wire mesh insert at the bottom which is made of the same mesh material used in the front grille. The rear spoiler is taller and wider, and encompasses the third brake light.

For the interior, the STS-V also has upgraded leather and suede trim contracted from the German company Dräxlmaier, whose prior credit includes the Maybach 57 and 62. Interior color choices were Ebony and Gray, both of which are offered on the standard STS as well, and a two-tone Ebony/Tango Red scheme which was unique to the STS-V.

Features

Standard features in 2006 & 2007 included;

Heated seats, express up & down windows, voice command of HVAC, windows, locks, audio, and NAV system. Blind spot warning system (flashing built into mirrors), automatic high & low beam system, backup proximity sensors, proximity digital key system, heated steering wheel, additional digital instrumentation (including boost, oil pressure, etc.) via the selectable vehicle module. Only a sunroof, head-up-display (HUD), and RainSense wipers were optional.

In 2008 and 2009 the model was lightly refreshed, including in the standard configuration a head-up display (HUD). This was available on all STS's starting in '05 but it was very expensive, thus why it is so rare to find outside of the '08/'09 V models. The refreshed version also offered standard RainSense (automatic) wipers which was an option on non-V STS vehicles. This matters only peculiarly, as Cadillac didn't offer RainSense wipers on any STS model in 2010 or in its last year of production, 2011.
