The 2008 Jeep Grand Cherokee gets a revamped look for the 2008 year model. In the grand tradition of new fitted engines in every vehicle's performance parts, the 2008 Jeep grand Cherokee delivers an efficient high-mannered engine performance which is on par with its style cues.

Details about the new Jeep Grand Cherokee and its Jeep parts will be shown off at the upcoming 2007 New York Auto Show. The new Grand Cherokee will be displayed in showrooms later this year.

The Jeep Grand Cherokee’s engine bay releases 291 horsepower and 322 pound-feet of maximum torque on a 4.7-liter V8. That’s a big leap from its previous powerplant that carries 235 horsepower and 305 pound-feet of torque. But similar to its predecessor, the new 4.7-liter V8 flex-fuel capable and can run on E85 or gasoline.

Owners of the 2008 Jeep Grand Cherokee can opt for five engine choices that would suit their driving styles. They are a 3.7-liter V6 that is standard on Grand Cherokee Laredo, a 3.0-liter common-rail diesel V6 that is optional on Grand Cherokee Limited and Overland, a 4.7-liter v8 that is standard on Grand Cherokee limited and standard on Overland and a 6.1-liter hemi V8 that is standard on Jeep Grand Cherokee SRT8. Specifications on all engines are an upscale on the Jeep Grand Cherokee’s modified engines. The new V8 gets twin spark plugs per cylinder and a higher compression ratio all of which bolsters its horsepower by 24 percent. Pretty impressive.

The interior design includes modern and functional styles that depict safety, comfort and convenience. The cabin is tinged with soft-trim touches and metallic trimmings which feature a two-tone instrument panel, updated clusters and a new standard tilt/telescoping steering column. The Jeep introduced three new safety and security technologies. For adventurous SUV users, the high-end technological touches consist of Hill Descent Control, Hill Start Assist and Trailer Sway Control.

On Jeep Grand Cherokee 4x4 models, the Hill Descent Control is definitely a standard. It offers downhill assistance at a controlled rate of speed. With Hill Start Assist, the control aids the driver make the transition from brake to full throttle on uphill grades. Trailer Sway Control is an additional option (for which owners of the Jeep can make rather haste choices) that enables trailer sway reduction.

Other features of the Jeep Grand Cherokee also include an optional Sirius Backseat TV, myGIG Multimedia Infotainment System, high-intensity discharge headlamps, a rearview camera, a backup warning system, an MP3 player input jack, memory seats and 18-inch chrome wheels.

Also, the outside styling of the Jeep Grand Cherokee has been updated. The grille has been stretched and integrates more circular headlights. The foglamps have been lowered and there is a new two-piece front fascia. The lower piece of the front fascia can be removed for off-road handling.

General Motors has unveiled a pair of new diesel engines for the Opel Astra. The new Opel Astra edition is modified to aptness providing varied enhancements to the vehicle’s auto body parts. It is now available to order with two innovative 1.7-liter diesel engines.

The latest generation common-rail turbo-diesel engines are compact and with their high-peak output prowess boosts ideal economy and low emission standards. When it comes to the diesel engines, they are mated with a six-speed manual transmission and maintenance free diesel particulate filter.

The 1.7-liter CDTI ECOTEC unit with 81 kW/110 hp produces 140 g of CO2 per kilometer and the 92 kW/125 hp version 146 g/km. Here’s the new generation of clean diesel engines:

•Six-speed transmission as standard
•Astra diesel engine range now includes six variants

Both the new 1.7 CDTI units in the third-generation Astra include common-rail direct injection, four valve technologies with swirl control and cooled exhaust gas recirculation with electropneumatic bypass flap control. The result: a highly refined direct response and superlative fuel economy. The compact turbocharged engines have a 79 mm bore and 86 mm stroke which provides a displacement of 1686 cubic centimeters. The cylinder head is created from light alloy and engine block from gray cast iron. Its 16 valves are triggered directly by two overhead camshafts by way of flat-base tappets; maximum injection pressure tops at 1800 bar. A turbocharger with variable vane technology ensures instant response times.

Opel/GM’s engineering team achieved the level of cleanliness (pertaining to the green them hoopla in the automotive industry) by improving exhaust gas recirculation system with a cooling function as addition. Electropneumatically operated bypass flaps, controlled by the engine management system, guarantee that the exhaust gas reaches a temperature proper for combustion on its way back into the cylinder.

With these new 1.7 CDTI engine sin tow, the Opel Astra runs impressively than ever before.

Nissan has delved into the production of its new QASHQAI 2.0-liter dCi engine at Nissan’s Sunerland factory. Nissan approximately studied its QASHQAI sales to be fitted with this diesel engine rating over to 25%. The engine’s co-developed with Nissan’s alliance-partner Renault which delivers high-peak performance much credit to its powerful characteristics and easy road handling. And yes, it’s got that sustainable mobility as well as also eco-friendly.

Nissan’s engineering team have particularly adapted the tune and engine mapping for the QASHQAI as it is the first ever application to this 2.0-liter dCi engine on a model with all-wheel drive transmission. Sure enough, the engine is a popular one among customers since the 2.0-liter dCi (engine codes M1D) revs up 110kW at 4,000 rpm and 320 Nm of torque at 2,000 rpm. It returns an economical figure of 42.8 mpg and CO2 emissions of 174 g/km when equipped with manual transmission and in 2WD configuration. Also, a six-speed automatic transmission is also available.

The engine also provides state-of-the-art technologies such as standard DPF and twin balancer camshafts, twin counter rotating balancer shafts and chain-driven camshafts. It has also a common-rail injection fuel parts that churns 1600 bar of pressure. Piezoelectric technology abounded by Bosch gives off an accurate control allowing a five squirt injection cycle: two pre-squirts, one main squirt and two post-squirts.

Here’s the gist:
The pre-squirts enhance engine acoustics by lessening the diesel clatter while the post-squirts maintain the main injection combustion to burn off filth. It does bring down pollutant emissions before exhaust gases have even left the combustion chamber.

The 2.0 dCi is fitted with a diesel particulate filter (DPF) with a periodic regeneration system. When the particulates that has been amassed from the engine emissions reach a specified level, the engine guns a process that’s called as the thermal regeneration (performs a second post-injection to overheat the exhaust gas).

Exhaust gas recirculation (EGR) produces a controlled temperature rise in the combustion chamber to minimize pollutant emission levels which improves the engine’s overall performance.

Nissan’s expectations become true to form since customers harbor its innovative equipments such as the QASHQAI engine and other Nissan parts providing a true alternative to the conventional compact car. Customers are looking forward to receiving the first deliveries of the 2.0-litre diesel equipped QASHQAI â€" 15% of all QASHQAI orders already received are for this version. Nissan will roll out 700 QASHQAIs at the end of April.

Volkswagen proves once again that small-capacity engines offer a true alternative to its huge and heavier engine counterparts. The automaker has used the annual International Motor Symposium here to introduce a new turbocharged 1.4-liter direct-injection four-cylinder TSI gasoline engine.

The compact unit churns out a claimed 122 horsepower along with 148 pound-feet of maximum torque at an ultra low 1,500 rpm. It surpasses its revved up capacities of VW's normally aspirated 1.6-liter direct-injection four-cylinder engine to the tune of 7 hp and 33 lb-ft.

The new engine is based on Volkswagen's impressive Twincharger power plant embedded to the Golf and Touran with a bore and stroke of 76.5 mm and 75.6 mm. It's definitely unlike the existing 140-hp and 170-hp Twincharger engines which it metes out with the supercharger, depending solely on a turbocharger to engorge its reserves.

Also exhibited in Vienna is Volkswagen's new seven-speed double-shift gearbox (DSG). The new unit, code-named DQ200 and perceive for torque loads of up to 148 lb-ft, differs from Volkswagen's existing six-speed unit, the DG250, by integrating a dry sump engineered by German specialist LUK. This arrangement does away with the need for expensive servicing.

Volkswagen's new turbocharged 1.4-liter engine and seven-speed double-clutch gearbox are claimed to provide the Golf with combined average fuel consumption that is the equivalent of 40 U.S. mpg in combination.

The engine unit's scheduled to hit into next year's all-new Polo and to go into the Golf and Touran later this year.
