Ford Police Interceptors dominate Michigan State Police testing

Once again, Ford Motor Company builds the fastest police vehicles. The Blue Oval touted the news in an official release following Michigan State Police and Los Angeles County Sheriff's Department testing. Ford did very well. Except for one acceleration metric – zero to 10 miles per hour – the Blue Oval's Taurus and Explorer-based cop cars were the quickest, with particular praise coming for the EcoBoost-powered models, which bested Chevrolet and Dodge's V8-powered variants. Dearborn's products also posted the fastest average times around MSP's vehicle dynamics course. But it wasn't all positive for Ford. The only four-cylinder in the contest, the 2.0-liter, EcoBoost Ford SSP Sedan, had both the lowest top speed, 120 mph, and the slowest acceleration figures. It was also the slowest in track testing. Ford's products also failed to match the braking and top speeds of its rivals from Detroit and Auburn Hills – the rear-drive Charger Pursuit posted the best braking stats of the entire test, while the V8-powered Chevrolet Caprice hit the highest top speed, at 155 mph. Ford did score a top speed award, among SUVs, but at 132 mph, the naturally aspirated Police Interceptor Utility had to share its award with the equally fast, rear-drive Chevrolet Tahoe. The LA County Sheriff's timing isn't publicly available, but according to Ford, the EcoBoost-powered police cars put on a similarly impressive show for cops on the West Coast. We've assembled a spreadsheet on Google Docs that offers an easy to browse comparison of the different stats assembled by the Michigan State Police, and divided the vehicles between standard V6-powered sedans, high-performance sedans (EcoBoost and V8 models), and SUVs.

2016 Dodge Viper ACR First Drive [w/video]

The Dodge Viper is not a comfortable car. Livable, yes. The interior is covered in fine materials. But you still climb over a hot door sill to enter the tiny cabin. And the frequency range of the engine's noises seem specifically designed to cause headaches. What happens, then, if you remove all pretense of civility from a Viper and add equipment solely aimed at improving lap times? You would have the 2016 Dodge Viper ACR. In terms of achieving its purpose, this car is a absolute success. In many ways it's also the most honest Viper of the current generation. Prices start at $121,990 (including $2,100 gas-guzzler tax and $1,995 destination), or $32,900 more than the least expensive Viper. In ACR trim, the Viper loses the under-carpet padding, 9 of 12 speakers plus amplifier, carpet and trim from the cargo area, and sound deadening in front of the rear wheel wells. The parts of the interior still covered add healthy amounts of Alcantara or optional carbon fiber. That weight loss is compensated by the addition of go-fast bits like the giant rear wing (or the larger "x-wing" on the Extreme Aero Package), 10-way adjustable Bilstein Motorsports shocks, Brembo carbon-ceramic brakes, a rear diffuser, and a front splitter. Total claimed curb weight is 3,392 pounds in Aero trim (standard ACR trim is 18 pounds lighter), which is within a few stone of the rest of the Viper lineup. The diffuser strakes and leading edge of the splitter are removable, made to be replaced after rubbing on track tarmac and make street driving slightly more practical. Not that you'd want to drive the ACR on the street, with the lack of noise insulation and spring rates twice as stiff as the Viper TA, but it is street-legal. Dodge claims the DOT-approved Kumho Ecsta V720 tires on the ACR allow faster lap times than some race compound tires. Our test was limited to on-track shenanigans at Virginia International Raceway. Which is fitting because we wouldn't have anything good to say about driving the car on the street. The ACR is, essentially, a race car sold in the showroom, although with the Viper's 1 of 1 customization program, your custom build can include as many creature comforts as you like. Lined up in pit lane at VIR, the Viper ACRs for our evaluation blur the air with heat shimmer. All of the test cars have air conditioning, but that shuts off at full throttle with a six-second reset.

Dodge Durango SRT vs. Jeep Grand Cherokee SRT | Which should you buy?

Choice is a good thing. And when it comes to high-performance sport utility vehicles, there are more choices today than ever before to tantalize buyers into showrooms. And why not? Americans love SUVs, and, while there's a stronger push to go green now than ever before in the history of internal combustion, there's still a large contingent of buyers who firmly believe in choosing the biggest, baddest, most powerful powerplant. For those buyers, the Dodge Durango SRT and Jeep Grand Cherokee SRT are two of the most potent options. But which one should you buy? They both deliver 475 horsepower and 470 pound-feet of torque to all four wheels through an eight-speed automatic transmission. They both do 0-60 in around 4.4 seconds, and both boast top speed numbers that will handily land you in jail if written on a speeding ticket. Choosing between the two, then, is a bit more nuanced than which is faster. That said, the Jeep is probably a bit quicker at the track than the Dodge. We'd wager than the Grand Cherokee SRT's 5,104-pound curb weight (versus 5,510 for the Durango SRT) and 114.8-inch wheelbase (versus 119.8) will pay small dividends in acceleration, cornering, and braking performance. So, if that's the only category by which you believe these SRT-fettled SUVs should be judged, choose the Jeep. View 17 Photos But let's get real here for a moment. As much fun as it is to wrangle a brutish ute 'round a racetrack – and trust us when we tell you it's a blast – the number of hi-po SUV owners who will ever show up at Bondurant in an SRT-badged 4x4 is probably in the single digits. So, when evaluating which of the two Hemi-powered vehicles is right for you, ultimate lap times are probably of little concern. If you're choosing between these two overpowered players, practicality is probably just as important as performance. And in that category, the Durango SRT comes out on top. For starters, the Dodge is a three-row SUV with six seats, whereas the Jeep is a two-row, five-passenger platform. Fold down the rear bench and there's 84.5 cubic feet of cargo area in the Durango, versus 68.7 in the Grand Cherokee. And if you tow, the Durango SRT's 8,600-pound max rating handily bests that of the Grand Cherokee SRT's 7,200-pound capacity. Ask yourself what's most important: performance or practicality. And then consider the price. The Dodge is nearly $4,000 less expensive than the Jeep.
