[LucioFire]

Il pèrimo scambio non lo farei...il secondo è il migliore...moto più macchina pressochè equivalente!

Il penultimo non vale perchè la porsche è cabrio

Taking a look at some of America's most iconic manmade machines over the past century or so reveals much about our national psyche. The World War II Iowa class battleship was among the most powerful ever built, with 212,000 shaft horsepower, nine 16-inch guns, and a displacement of 58,000 tons by the time it went out of service. The big Grumman F6F Hellcat was one of the deadliest naval fighters of all time. The Saturn V rocket is the tallest, heaviest, and most powerful rocket ever made, producing more than 1 million pounds of thrust.

Big power isn't just limited to our war and space machines. Our cars are powerful too, as evidenced by the two iconic musclecars gracing this article. The recently refreshed 2014 Chevrolet Camaro ZL1 is the most powerful Camaro ever made, with 580 hp on tap. The 2015 Dodge Challenger SRT Hellcat, also new this year, is among the most powerful mass-production vehicles ever made, with 707 screaming ponies under the hood. With Ford and its 662-hp Shelby Mustang currently out of the production, the Camaro ZL1 and Challenger Hellcat and their combined 1287 horsepower represent the two toughest musclecars around. One has to be better than the other, though, and as was the case back in the musclecar's heyday, the winner of this comparo must show itself to be dominant at the test track, fast in a straight line, be the best boulevard cruiser, and ooze street presence. With that in mind, we saddled up and took these two steroid-injected ponycars to some of SoCal's most iconic Americana hot spots to figure out which is best.

Comparing the 707-hp Challenger Hellcat to the 580-hp Camaro ZL1 isn't exactly a one-sided affair. Both musclecars are powered by supercharged 6.2-liter V-8s, with the Camaro's LSA featuring a 1.9-liter Roots type blower, while the Challenger's Hemi Hellcat has a 2.4-liter Lysholm blower on top. Though the Camaro only produces an SAE-certified 580 hp and 556 lb-ft of torque compared to the Challenger's 707 hp and 650 lb-ft of torque (at the crank; see our the related Challenger/Camaro blog for wheel hp, it makes up the difference with a curb weight about 400 pounds less than the Challenger's. Besides, the Camaro beat the 662-hp 2013 Ford Shelby GT500 in its last go-around. The Challenger sports the optional eight-speed automatic (a six-speed manual is standard) and the Camaro has the standard six-speed manual. Both cars feature electronically adjustable suspensions and a variety of performance driving modes.

The first stop for our pearlescent Sublime Green Challenger Hellcat and our Silver Ice Metallic Camaro ZL1 was our test track, where we were eager to see what kind of numbers the two cars would throw down. The Camaro ZL1 was the poster child for consistency with a 3.9-second 0-60-mph run, blasting through the quarter mile in 12.2 seconds at 116.6 mph. That's fast any way you look at it, and yet the Dodge makes the Chevy feel oh so slow. Not surprisingly with more than 700 horsepower on tap and narrow 275-width Pirelli P Zero rear tires, the Challenger proved difficult to launch even with launch control enabled. The drag-race-ready Challenger's best 0-60 mph run was with a second-gear start, resulting in a 3.7-second time, and an impressive quarter-mile performance of 11.7 seconds at a stupid-fast 125.4 mph. That trap speed doesn't embarrass Camaro ZL1 owners alone, but both Nissan GT-R Nismo and Porsche 911 Turbo S owners, too.

The figure eight did much to reveal the different intended functions of the Camaro and the Challenger. The Camaro is well-balanced; you can tell its engineers were just as interested in making a track-capable car as they were a street-racer. The ZL1 is well-suited for handling work, with quick, accurate steering that weights up nicely, and a well-controlled ride, thanks to GM's trick magnetic shocks. The ZL1 lapped the figure eight in 24.0 seconds at a 0.85 g average, and pulled 0.99 g average on the skidpad. Lapping the Camaro quickly is an exercise in point and shoot, as the Chevy for the most part just sticks and goes without the driver having to do much work at all.

While the Camaro behaves like a sports car, the Challenger pretends to be nothing else than a straight-line dragster, and when you toss a corner its way it can be a handful. As associate editor Scott Evans put it, the Hellcat handles "just like a Challenger. Understeer into the corner, oversteer out." The quickest way around the figure eight ultimately was the old tried and true racing mantra of "slow in, fast out" as you lap the boat-like car. The result is still pretty impressive, even if it doesn't feel it, with a 24.7-second figure-eight time with a 0.85 average g, and a 0.94 lateral g average skidpad performance. The Hellcat may not inspire confidence in the corners, but it'll do the most glorious drifts you can possibly imagine as it shreds through its rear tires.

In sintesi la Camaro ha una dinamica di guida migliore,il gattaccio è ottimo per fare gli spari e i traversi:mrgreen:

Troppo anni 70 e troppo tamarra quindi bellissima per me!

Se poi andiamo a vedere il prezzo paragonoato all'alfa non c'è storia

Andrebbe presa solo per il "non avere nessun senso di esistere".

Magari gli americano non le sapranno far curvare ma le auto le sanno fare eccome Che delizia l'urlo del compressore

Buyers of the 707 horsepower Dodge Challenger SRT Hellcat likely have little care for their fuel mileage, but it is far above the single-digit range the 426 Hemi was known for (and above some other supercars): owners can get 22 mpg on the highway, according to Chrysler/EPA testing, if they use the eight-speed automatic.

The Chevrolet Camaro ZL1, which has a supercharged 6.2 liter V8 is rated at a much lower 12 city, 18 highway with its automatic (16/19 with the manual). It is rated at 580 horsepower, and starts at $55,505.

The 2015 Challenger Hellcat, with a supercharged Hemi V8, lists at just under $60,000. It can run 10.8-second quarter miles (NHRA certified), making it the second fastest muscle car every measured, after the Charger Hellcat; Chevrolet rates the fastest ZL1 at 12.0 seconds (the automatic coupe). The 7-liter Z28 (505 hp) quarter mile time is close at 12.04 seconds; the Z28 costs $75,000.

By comparison, Chrysler noted that the (Volkswagen) Lamborghini Aventador Roadster, at $425,845, generates 700 horsepower but goes just 18 miles on a gallon. The $287,820 Aston Marton Vanquish, with 576 horsepower, is also at 18 mpg, while the Mercedes SLS AMG GT, at $221,580, pushes out 583 horsepower and is rated at 19 mpg.

The Chrysler-developed Hellcat engine boasts a forged steel crankshaft with induction hardened bearing surfaces that can withstand 110-bar firing pressures. The heads are heat-treated and optimized for thermal conductivity. The twin-screw 2,380-cc/rev supercharger has integral charge coolers and an electronic bypass to keep boost pressure to 11.6 psi or less. Air temperatures are kept below 140° F by twin air/coolant heat exchangers, integrated into the supercharger housing, which allow airflow of 30,000 liters/minute. The setup was designed to assure constant power through 20 laps of a 3.1 mile road course at an ambient temperature of 100°F.

The handle the torque, Hellcat cars with automatics have one additional pinion gear in each of the 1st and 3rd gear sets, and five more clutch-pack disks – two in clutch E and one each in clutches A, C and D.

With the six-speed manual transmission, economy drops to 21 mpg. This transmission has an internal cooling pump and external oil cooler, with a 258 mm clutch.

Dodge did not release city or combined mileage, and the EPA has not yet posted Hellcat figures on its Web site. The standard Dodge Challenger SRT8 (485 hp) achieves 15 city, 25 highway with the automatic and 14 city, 23 highway with the manual.

The Dodge Viper is rated at 12 mpg city, 21 highway.

Beh, consuma meno della MiTo EVO™ in autostrada (circa 8,5 km/l ai 130 di cruise).
