Jumping into the real meat of these cars; the Series 4 and Series 5 sport a Hurst Supercharger which is essentially a Vortech unit.  The spent exhaust exits through a Magnaflow stainless steel cat-back exhaust and a K&N intake feeds fresh air into the supercharger.  These 2 power upgrades combine for over 570 horsepower and 525 lb-ft of torque.  This represents a 150 bump in HP and 100 bump in torque over the stock Hemi powered 2010 Dodge SRT8.

Moving to the exterior the car rocks sweet 20 inch forged rims with painted inserts.  These rims are wrapped in super sticky BF Goodrich KDW tires.   Out back a Hurst Airspeed spoiler adds to the appeal of the car.  Any self respecting modified car has to be lowered and the 2010 Hurst Hemi Challenger Series 4 rocks a full Eibach adjustable coil-over suspension with sway bars.  There are also 2 limited edition colors to choose from; black with gold racing stripes and silver with black and red racing stripes.  Special badges and graphics round out the exterior mods.

On the inside you get a limited Hurst Hard-Drive pistol shifter that comes anodized red.  Katzkin has created black leather interior with cool red stitching and Hurst logos.  There are special floor mats and dash badges that have the limited number info on them.

The cost of the Series 4 upgrade that includes all mentioned above and more comes in at $29,000 and that’s after you buy a new Dodge Challenger!  But you can bet that these cars will one day be collector’s items.

The new 2009 Cadillac CTS-V comes with a supercharged V-8 engine from the new Corvette; pumping out 556 horsepower! And although the car weighs over 4000 pounds, it somehow recorded the fastest lap time at the Nurburgring for a sedan on stock tires. This may not mean much until you think about the competition. The BMW M5 retails for $85k, the Mercedes E63 AMG sell for around $80k; both of these also have over 500 horsepower and yet for $20k more they are slower than the Caddy. This goes to show that while most American Automakers are going down in flames, Cadillac has saved the best for last.

Of course Grandpa will be perfectly happy with the refined interior which includes expensive Recaro racing seats, and the uniquely Cadillac exterior. But it’s the stoplight confrontations that will ultimately get grandpa to fill his Depends.
