Cadillac created the V-Series Concept in 2004, with the release of the 2004 Cadillac CTS-V.\u00a0 V stands for Velocity.\u00a0 V-Series Cadillacs are luxury vehicles, as are all Cadillacs.\u00a0 But they are also Gentleman Racers.\u00a0 The V-Series features more than adequate\u00a0 power plants, high performance track-tuned suspensions, high performance braking systems, additional engine and transmission cooling, and generally heavy-duty, series gear for enthusiasts who want to have serious fun with their Cadillac.<\/p>\n
The Cadillac STS-V was produced from 2006 through 2009.\u00a0 It featured the Sigma platform, Sachs tuned suspension, 4-piston Brembo Brakes front and rear, a 469 hp Supercharged (MP122) 4.4L DOHC VVT V8, and all the luxury features and accommodations available on the Cadillac STS.<\/p>\n
Performance:<\/strong> the performance of the STS-V should be similar across the various production years, because the weight and power did not vary.\u00a0 0-60 mph time was measured in around 4.8-5.1 sec depending on the magazine and the day.\u00a0 Quartermile time is 13.1-13.3 sec at around 106 mph.\u00a0\u00a0 Skidpad performance was measured as high as 0.90g and as low as 0.83g.\u00a0 Knowing the hardware I feel that 0.87g – 0.90g is probably representative.\u00a0 Top speed is electronically limited to 155 mph.<\/p>\n The STS-V uses a Magnusson MP122 supercharger, putting out 12 psi.\u00a0\u00a0 So for argument sake, knowing that atmospheric pressure at sea level is 14.7 psi, and knowing that a supercharger adds approximately 4% power per psi, we can calculate that the supercharger adds 48% power.\u00a0 Max efficiency is 7%\/psi, but 4%\/psi with real-world efficiencies and pumping losses. So the base 4.4L DOHC VVT V8 unblown might make 316 hp.\u00a0 And we can recognize that the tuning that this hand-built gem of an engine received at the Tech Center allows the lower-displacement 4.4L Northstar without the supercharger would make similar power to the normally aspirated 4.6L DOHC VVT Northstar, which makes 320 hp.<\/p>\n One example of the detail work on the STS-V is that the exhaust ports and head of the engine are extrude honed.\u00a0 This is a process that forces an abrasive material through the heads.\u00a0 Typically used in racing applications, this increases horsepower by increasing the airflow through the engine.<\/p>\n The STS-V’s 469 horses arrive at 6400 rpm, but at least 395 of the 439 peak pound-feet of torque are available between 2200 and 6000 rpm.\u00a0 The idle quality of the STS-V is even more stable than the already exemplary STS, due to the increased rolling inertia of the Supercharger.<\/p>\n All Superchargers generate heat; it is a by-product of compression.\u00a0 The STS-V uses an air to liquid intercooler to help reduce the heat of the incoming air charge, with a separate cooling system for the intercooler.<\/p>\n Pricing:<\/strong><\/p>\n Kbb.com is a great resource for used vehicle pricing.\u00a0 Currently they suggest the following STS-V pricing for a used example with 30K miles:<\/p>\n 2006: $24-26K Private Sale; $29K Retail<\/p>\n 2007: $28k-30K Private Sale; $33K Retail<\/p>\n 2008: $30-32K Private Sale; $36k Retail<\/p>\n 2009: $43-46K Private Sale; $50k Retail<\/p>\n Newer models will continue to be under Warranty.\u00a0 Also, in 2008 the STS-V gained a Heads-Up-Display (HUD), which is a desirable feature.\u00a0 I hope to continue to monitor STS-V pricing, and pick up a 2008 Model once they are available around $25K for a very good example with under 30K miles.<\/p>\n","protected":false},"excerpt":{"rendered":" Cadillac created the V-Series Concept in 2004, with the release of the 2004 Cadillac CTS-V.\u00a0 V stands for Velocity.\u00a0 V-Series Cadillacs are luxury vehicles, as are all Cadillacs.\u00a0 But they are also Gentleman Racers.\u00a0 The V-Series features more than adequate\u00a0 … Continue reading
