2008 Shelby gt500 mustang vs. 2008 challenger srt8 grade 6 science electricity unit test

The Shelby GT500 Mustang rides on 18 x 9.5-inch machined aluminum wheels with SVT center caps. It features P255/45Z18 front tires and P285/40ZR18 rear tires. Braking is achieved with the help of Brembo 14-inch vented discs fitted with four-piston aluminum calipers in the front and 11.8-inch diameter vented discs fitted with two-piston calipers in the back.

While the 2008 Challenger SRT8 is only available with an automatic transmission, the Shelby GT500 is only available with a Tremec TR6060 6-speed manual transmission. Let’s be honest. Most performance vehicles are equipped with a standard transmission. Is this a weak point for the Challenger SRT8? You be the judge. Powertrain

According to a road test in the July 2006 issue of Car and Driver magazine, the boys from Ann Arbor clocked their Shelby GT500 at 0-60 mph in 4.5 seconds with the quarter-mile at 12.9 seconds. Although the Challenger SRT8 is quick, it does appear as though the Shelby GT500 is the faster of the two.

Pricing and Efficiency: Closely Matched But The Mustang Gets Better MileageI’ve said it before and I’ll say it again; nothing in life is free. If you want a car that can outperform the competition, be prepared to pay the price. Fortunately, buyers looking for the better deal will find the 2008 Shelby GT500 and 2008 Dodge Challenger SRT8 similarly priced.

Ford’s destination fee for this pony car is $745. Shelby GT500 owners can expect to get 14 mpg city/20 mpg highway with an EPA estimated fuel cost of $3,009 based on 15,000 miles a year. The EPA says it costs $5.35 to drive the 2008 Dodge Challenger SRT8 25 miles, while the cost to drive the Shelby GT500 25 miles is $5.02.

The 2008 Challenger SRT8 has an MSPR of $40,095 and a destination charge of $675. As for gas mileage, owners can expect to get 13 mpg city/18 mpg highway. The EPA estimates an annual gasoline cost of $3,212 for the Challenger, which is based on 15,000 miles a year. There is a $2,100 gas-guzzler tax associated with a Challenger SRT8 purchase. The Shelby GT500 comes with $1,300 gas-guzzler tax.

Interior: Challenger Offers More Standard FeaturesIn the early days, performance vehicles didn’t need spectacular interiors. Their job was to provide exceptional performance. Things have changed. In a world where automotive manufacturers will do almost anything to move inventory, interior features are as important as the number of horses under the hood. There’s nothing wrong with that. As such, both the Challenger SRT8 and the Shelby GT500 Mustang are both well equipped.

For instance, the 2008 Shelby GT500 Mustang features leather sport bucket seats with Snake logos embossed in the seatbacks and comes with full power accessories. It also includes a leather-wrapped steering wheel and a Shaker 500 AM/FM stereo with six-disc CD/MP3 capable player and eight speakers. Don’t forget its unique shift knob with leather shift boot and parking brake handle. An ambient lighting option is also available for those looking to change the color of their Shelby interior at night.

For an additional price buyers can move up to the GT500 Premium Interior Trim Package which includes wrapped and stitched instrument panel brow and center condole with upgraded door armrest, electrochromic rearview mirror, and aluminum pedal covers. Other optional features include Sirius satellite radio and a 1000 watt audio system with AM/FM stereo, in-dash six-disc CD/MP3 player, and 10 speakers.

The Challenger SRT8, on the other hand, comes standard with heated leather front-sport seats, full power accessories, cruise control, an auto-dimming rearview mirror, heated side mirrors, and a 60/40-split-folding rear seat. As for audio, buyers get a 13-speaker Kicker High Performance audio system which features a 322-watt amplifier and 200-watt subwoofer, and SIRIUS Satellite Radio. A MyGIG infotainment system with navigation, as well as a sunroof, is available for an additional cost.

Overall, the Challenger offers up more standard interior features than the Mustang does. This should come as no surprise to the many Mustang owners who have told me the Ford Mustang’s interior needs to be reworked. If Ford were to include the GT500 Premium Interior Trim Package as standard equipment, the two would be more closely matched. The Mustang does offer a more powerful sound system with the 500-watt Shaker 500 setup. Unfortunately, heated seats are an additional cost, while heated-side mirrors are not an option at all. The 2008 Shelby GT500 does not come with a sunroof option. Shelby buyers can purchase a convertible GT500 instead. INTERIOR FEATURES AND STANDARD EQUIPMENT 2008 Dodge Challenger SRT8

The Final Word: Performance Car or Performance PR?When all is said and done, it’s easy to see there are obvious differences between the 2008 Challenger SRT8 and the Shelby GT500. Yes, the Challenger SRT8 is a performance vehicle, but why did Dodge decide to only offer it up with an automatic transmission? Being able to determine your own shift points is important when driving a performance car. Die-hard performance enthusiasts will most likely see this as an apparent weakness.

Another observation is that of power and performance times. With a 6.1L SRT HEMI V8 engine, one would think the Challenger would be a beast of a machine. It’s fast, I’ll give Dodge that, but as recent road tests confirm, the SRT8 Challenger is a slightly slower ride than the Shelby GT500. It’s a close match up, less than a second off the lead of the GT500 in the 0-60 and 1/4 mile time trials. But the Shelby still wins out in the end. A Motor Trend comparison test further proved that the Shelby GT500 is quicker than the Challenger.

In its current form, the Challenger comes off as a performance car designed for wealthy commuters and daily drivers; not a performance car designed for performance drivers. With a few minor tweaks here and there, the car is a solid performer.
