2013 Dodge Challenger R/T hits the Redline

Dodge has added a bit of spice to its Hemi-powered Challenger for 2013, offering up this new Redline package that makes its official debut at the Chicago Auto Show. The R/T Redline builds on the Rallye Redline kit that was created for the V6 Challenger, and we like how these subtle changes add to the muscle coupe's already classic styling.
In addition to the black chrome 20-inch wheels with red accents, the R/T Redline adds subtle graphics along the beltline. Inside, cars equipped with the six-speed manual transmission get a performance tuned exhaust that allows the engine to send a full 375 horsepower and 410 pound-feet of torque to the rear wheels. (Redline Challengers with the five-speed automatic produce 372 hp and 400 lb-ft.)
The Redline package retails for $1,995 and can be had on both Challenger R/T and R/T Plus models. Scroll down for the full press blast.

2020 Ford Police Interceptor Utility dominates Michigan State Police testing

The Michigan State Police has released its preliminary findings from testing the 2019 crop of police vehicles, and the results are a bit surprising. The consistent top performer of the bunch was the 2020 Ford Police Interceptor Utility, better known to civilians as the Ford Explorer. Specifically, the top performer was the model with the new turbocharged 3.0-liter V6. The Michigan State Police conducts acceleration, top speed, braking and lap time tests of all the available police vehicles. The 3.0-liter Police Interceptor Utility was the fastest to 60 mph at 5.77 seconds, had the highest top speed of 150 mph, and the best average lap time of 1:36.47. The lap time was particularly impressive as it was just over half a second faster than the next quickest car, the all-wheel-drive V8 Charger.

The all-wheel-drive V8 Charger was only 0.1 seconds behind the Explorer to 60 mph with a time of 5.87 seconds, and the rear-drive version was third quickest at 6.15 seconds. Both V8 Chargers were only 1 mph off of the Explorer's top speed, and the V6 example was third fastest at 141 mph. We already mentioned the all-wheel-drive V8 Charger was half a second off the Explorer's lap time, and the rear-drive variant was just over 1 second behind, giving it the third fastest average time. Dodge also took home braking bragging rights. The V6 Charger won out with a distance of 126.9 feet, followed by the rear-drive V8 Charger with 128 feet, and the V6 Durango Pursuit stopping at 128.8 feet. Now of course where there are winners, there are also losers. The slowest accelerating police car was the Ford Police Responder Hybrid Sedan, better known as the Fusion Hybrid, with a time of 9.24 seconds. At 8.59 seconds was the V6 Dodge Durango, and the V8 Chevy Tahoe with four-wheel-drive was third slowest at 7.98 seconds. Lowest top speed was 106 mph with the Ford F-150 Police Responder with the 3.5-liter turbocharged V6, followed by the V6 and V8 Durangos with 117- and 118-mph top speeds respectively. In braking, the Chevy Tahoes performed the worst with the rear-drive version stopping at 145.7 feet and the four-wheel-drive version stopping at 142.5 feet. The F-150 followed with 141.9 feet. When it came to lap times, the Fusion Hybrid lapped the slowest with a time of 1:46.31. The V6 Durango was about a second faster with a time of 1:45.45.

Dodge Demon's A/C helps its supercharged Hemi make more power

Staying cool is one important key to performance. Simply, more air means more power, and cool, dense air is better than hot air. While forced induction might help make copious amounts of horsepower, turbos and superchargers produce heat. Intercoolers help, but the new Dodge Demon and its supercharged Hemi need a bit of an extra boost. In Drag Mode, the Demon's engine commandeers the car's air conditioning system to help chill things out. The Demon will have the first production application of a liquid-to-air charge air cooler chiller system. Literally, the car's air conditioning system is used to cool the air going into the engine, dropping temps by up to 45 degrees Fahrenheit. Dodge claims the system helps achieve "temperatures previously unattainable by pressure-charged street-legal production vehicles." As cool as this may sound, the technology isn't new. Ford had a prototype system in the early 2000s called SuperCooler, though that system never made it to production. While the Demon's system doesn't have a super cool name like the one from Ford, the pair essentially work in the same way. In theory, it should have the same effect as a bottle of nitrous. According to Autoweek, Ford's system bumped up the output of the F-150 Lightning by about 50 horsepower. Turns out that air conditioning isn't always a huge power suck. Related Video:
