Given that over forty per cent of all cars sold in Europe are diesel-powered, any brand that wants to be successful in the market must have diesel options in its range. Following the presentation of its new 3.0-liter V6 turbo diesel on the Chrysler 300's European clone, the Lancia Thema, the Fiat Group is now introducing the oil-burner to the Jeep Grand Cherokee range for Europe and other diesel markets around the world. The new V6 diesel engine is built by VM Motori and has been developed together with Fiat Powertrain, which is a subsidiary of the Fiat Group. The 3.0-liter unit features Fiat's MultiJet II system which enables up to eight injections per cycle, with the possibility of managing the two main injections in a single modular profile (IRS – Injection Rate Shaping). It is also fitted with a single Garrett VGT 2056 turbocharger with variable turbine geometry.
In the Grand Cherokee, the 3.0-liter V6 diesel is offered in two guises, the most powerful of which produces 241HP at 4,000 rpm and 550 Nm (406 lb-ft) of peak torque at 1,800-2,800 rpm, with the company claiming a 10 percent gain in power and eight percent more torque than the engine it replaces.
Despite the improved performance, Jeep said fuel economy for the 241HP version returns 8.3 lt/100km (equal to 28.4 mpg US) on the combined European cycle, an improvement of 17 percent over the prior diesel engine. CO2 emissions (are also reduced by 17 percent, now at 218 g/km.
Jeep will also offer a lower-output version of the 3.0-liter V6 turbo diesel rated at 190HP at 4,000 rpm and 440 Nm (324 lb-ft) of peak torque available from 1,600 to 2,800 rpm. The low-output version of the turbo diesel engine will be standard on Laredo models and optional on the Limited
The new 3.0-liter turbo diesel variants of the Grand Cherokee will receive their world premiere at the Geneva Motor Show next week and be available in Europe by the end of the first half of 2011.
