Jeep to showcase new Grand Cherokee production-intent sport concept with 3.0L Multijet II diesel at Geneva Motor Show

This year at the 82nd Geneva Motor Show, Jeep will showcase the European première of a Jeep Grand Cherokee production-intent sports concept powered by the new 3.0-liter V-6 turbo-diesel engine with Multijet II technology. (Earlier post.)

The engine produces maximum power of 177 kW (241 hp) at 4,000 rpm and torque of 550 N·m (406 lb-ft) at 1,800-2,800 rpm and it is paired to the five-speed automatic transmission with Electronic Range Select (ERS). The 3.0-liter CRD powertrain is also offered in a low-output version, with 140 kW (190 hp) of power at 4,000 rpm and 440 Nm (324 lb-ft) of torque across 1,600-2,800 rpm.

The 3.0L diesel features new-generation, 1,800-bar injectors and Multijet II technology developed and patented by Fiat Powertrain. With the new MultiJet II technology, which makes use of a special balanced solenoid valve, the new injector is capable of making up to 8 injection per cycle with the possibility of managing the two main injections in a single modular profile (IRS – Injection Rate Shaping) thus guaranteeing a reduction in consumption and polluting emissions of approximately 2% compared to a traditional injector and ensuring a drastic reduction in noise levels.

At the unveiling of the 3.0-liter turbo diesel engine at the Geneva show in 2011, Jeep said that the fuel consumption was 8.3 L/100km (28 mpg US) on the combined cycle, an improvement of 17% over the prior diesel engine. CO2 emissions (combined cycle) are also reduced by 17%, now at 218 g/km.

The new production-intent sports concept is equipped with the Quadra-Trac II 4x4 system with two-speed transfer case and Brake Traction Control System (BTCS) on both the front and rear axle to ensure benchmark off-road capability. Quadra-Trac II's two-speed transfer case uses the inputs coming from a variety of sensors in order to determine tire slip at the earliest possible time and take corrective actions.

The system uses Throttle Anticipate to sense quick movement in the throttle from a stop and maximizes traction before slippage occurs. When tire slippage is detected, 100% of the available torque is instantly routed to the axle with the most traction. Off-road capabilities are accomplished through the assistance of standard Hill Descent Control, for maximum downhill control, and Hill Start Assist, granting a smooth launch on a grade.

The new Jeep Grand Cherokee production-intent sports concept offers an array of advanced safety and security features. In addition to the standard safety equipment including Electronic Stability Control (ESC) with Electronic Rollover Mitigation (ERM), ABS with off-road calibration, Brake Traction Control System (BTCS) and 7 airbags (front seat, sidebags, side-curtain front and rear, seat-mounted), the sports concept adds Adaptive Cruise Control, Forward Collision Warning and Blind Spot Detection with Rear Cross-path detection.

  • Adaptive Cruise Control: the system decreases the vehicle’s pre-set cruise-control speed when closing in on another vehicle in the same lane, or when another vehicle pulls into the same lane. The system will accelerate to the pre-set speed when the vehicle in front speeds up or moves into another lane.

  • Forward Collision Warning: using forward-facing radar sensors, this system detects when the vehicle may be approaching another vehicle too rapidly and alerts the driver so the driver can determine what action must be taken in order to prevent the vehicle from a collision.

  • Blind Spot Detection: the system uses dual ultra-wideband radar sensors to aid the driver when changing lanes, or if being passed by or passing unseen vehicles. The system notifies the driver of vehicle(s) in their blind spot via illuminated icons on the sideview mirror and with a driver-selected audible chime.

  • Rear Cross-path detection: in parking lot situations, this system warns drivers backing out of parking spaces of traffic moving toward their vehicle. It activates any time the vehicle is in Reverse. The driver is notified of vehicle(s) crossing behind the vehicle via illuminated icons on the sideview mirror and with a driver-selected audible chime.



If I was to spend the money to get a Grand Cherokee, the only version I would want would be equipped with a 400+ horsepower Hemi V-8.


A V-12 twin turbo would burn more fuel?



Burn as much fuel as possible - a true American lifestyle!



So, help me out here... The article discusses the benefits of this new system, including 28 MPG for a decent sized SUV and somehow all you could think of is "Burn as much fuel as possible - a true American lifestyle!"

What???? Did all you see was Jeep Grand Cherokee and stop reading, only two spew that??

I think those comments were in response to ejj's comment about getting a HEMI engine instead.

A little sad to see the engine coupled with an old five-speed gearbox to ruin the fuel economy again. The new 8-speed automatic transmission from BMW has lower fuel consumption than its manual counterpart. That's what we need!


why isnt' the fuel consumption of the detuned diesel engine is not listed?
