Pop The Hood: 2014 Jaguar F-Type V8 S



If you listen closely to the anger-induced howl of the 2014 Jaguar F-Type V8 S, it can be hard to tell whether the car is better suited for tearing up racetracks or stalking through the jungle in search of prey. Thatís thanks to an innovative 5.0L supercharged engine up front, so letís find out exactly what Jaguar did to create this crackling beast.

The 2014 F-Type pumps a whopping 495 horsepower and 460 lb.-ft. of torque out of the engine. Perhaps most impressive is that in the F-Type V8 S, full torque is available from 2,500-5,500rpm. All told, itís enough to reach 0-60mph in just 4.2 seconds. Jaguar achieved that by keeping the weight low (3,671 lbs. in the V8 S) and the technology high.

The all-alloy engine, codenamed the AJ133, has been developed since 2001 and used in other cars like the Jaguar XF-R. For the all-new F-Type, features like an Intelligent Start-Stop System with a twin solenoid starter and high-compression direct injection have been added to increase efficiency.

Cylinder heads are also made of aluminum to decrease weight, and they work in sync with a Dual Independent Variable Cam Timing (DIVCT) system. The DIVCT is actuated by the torque being generated, so within milliseconds it can deliver the perfect amount of engine oil into the camshafts based on movement of the intake and exhaust valves. Not a drop more or less than necessary, which would explain the invigorating throttle response in the 2014 F-Type.

Quickness is great, but power still reigns supreme. For that, the 2014 Jaguar F-Type V8 S turns to a Roots-type Twin Vortex Supercharger mounted inside the V8. A water-cooled intercooler works to lower the air temperature, increasing both power and efficiency as the twin four-lobe rotors pump air into the 5.0L engine at incredible speed. If that power is a little too accessible, the 2014 F-Type is equipped with electronic limited slip differential, applying power and braking to the rear wheels as needed.

Perhaps our favorite feature on the 2014 Jaguar F-Type V8 S, however, is the new active exhaust system. Cruise along leisurely and the engine will produce a pleasant hum. Push the engine past 3,000rpm, however, and the electronic bypass valves open up for free-flowing exhaust that sounds downright primal. The prestige you get from owning a Jaguar is all fine and dandy, but itís that incredible sound Ė and the technology behind it Ė that make the 2014 Jaguar F-Type V8 S truly lustworthy.
