    Grand Master: SRT8 version of the Grand Cherokee is the most potent Jeep yet

    [​IMG]

    If Daimler Chrysler decided to make, oh, say riding lawn mowers, we’re sure an engineer there would find a way to stuff a Hemi in. Then DCX’s Street and Racing Technology division would follow that up with an even more over-the-top SRT version.

    Crazy as that sounds, we would probably like it.

    That’s because we really like the latest SRT-massaged product. While other manufacturers—BMW, Mercedes, Porsche and Land Rover—produce high-performance sport/utes, turning a Jeep into a 400-plus-hp screamer would have seemed, just a few years ago, as improbable as a V8-powered grass cutter.

    The Grand Cherokee SRT8 is the quickest, most powerful Jeep ever. It is also the first Jeep to wear the SRT badge. With a 0-to-60 mph time of less than five seconds, the SRT8 is quicker than the Porsche Cayenne Turbo (5.16 seconds) and BMW’s X5 4.8is (6.8 seconds). That 60-mph sprint is even more impressive considering the Grand Cherokee weighs 4788 pounds.

    Four-piston Brembo calipers cover 14.2-inch front rotors and 13.8-inch rears to bring things to a halt from 60 mph in 125 feet. Top speed is 155 mph.

    The big Hemi starts life as a 5.7-liter powerplant that gets breathed on considerably, with a bigger bore, higher-compression cylinder heads, larger intake and exhaust manifolds, and larger camshaft profiles. A forged crankshaft, high-strength connecting rods, floating-pin pistons and a modified lubrication system round out the Hemi’s go-faster profile.

    The 6.1-liter engine provides thrust and makes 420 hp and 420 lb-ft of torque. Maximum horse*power comes on at 6000 revs, just 200 rpm below redline, while peak torque comes on at 4800 rpm. Power is routed through a beefed-up five-speed automatic transmission. AutoStick is standard.

    Because this is a Jeep, SRT engineers worked on the vehicle’s full-time four-wheel-drive system to handle its massive torque. They created a transfer case with a single-speed electronically controlled clutch to direct power to all wheels. An electronic stability program monitors wheel speed and throttle position to decide where to mete out the torque.

    Under normal driving conditions 10 percent of the torque is sent to the front wheels. If conditions warrant, 100 percent can be routed to the wheels with traction.

    Stepping hard on the throttle on dry pavement produces a minor tire chirp—at most—and then you’re gone, pinned into the SRT8’s firm leather contour*ed seats. Taking into consideration the vehicle’s heft, acceleration is stunning.

    If the pavement is uneven, there is some tram-lining due to the huge 20-inch, five-spoke alumi*num wheels fitted with Goodyear W-rated all-season run-flat tires—255/45 in front and 285/40 in back.

    Despite the low-profile tires and lowered suspension (the SRT8 rides one inch lower than a standard Grand Cherokee),the firm ride is not as harsh as could be anticipated; steering is direct with minimal body roll. The truck’s wide, lowered stance and big rubber urges you to attack corners like you’re in a sports car. But never forget that you’re not.

    Exterior modifications to this Grand Cherokee include a lowered front fascia to reduce lift and provide airflow to cool the engine. A rear fascia with a center cutout is for the dual four-inch chrome exhaust tips. Interior refinements include the wraparound SRT seats and minor trim pieces.

    As the Grand Cherokee SRT8 is not trail-rated—Jeep-speak for being a heavy-duty off-roader—the truck should not be on the shortlist for your next Rubicon excursion. But who cares? As a daily driver, the SRT8’s entertainment factor is extremely high. Averaging about 13 mpg in our stint, though, we recommend you don’t venture where the gas stations are too far apart.

    I've been trying to get my hands on one for a test drive, but no luck. The DCX bigwigs are hogging the good pool vehicles. :wtc:

    Fuck the haters. Pretty cool idea IMO. 4.9 0-60 is decent for a goddamn 4,800 lb beast.

    Yes, fatties need not apply (the seats are heavily bolstered and not Fattie Rated).

    Are they making a Grand right now with a Hemi that's capable of towing anything?
