According to AutoWeek news, General Motors Australian brand Holden will be producing a new V12 that’s going to fit in the Cadillac flagship.

AutoWeek’s cover story reveals that the Holden Division is developing hardware for a new supersedan which the V12 will be embedded in. The roadster will be based upon the design from the 2003 Cadillac Sixteen concept car. The vehicle is christened as the Cadillac twelve which would compete against other car competitions ranging from the Mercedes-Benz S Class to the Audi R8 although it is also set to receive the XLS name.

Obviously, the production of such a major V12 engine will catapult GM’s return as The Standard of the World. The characteristically suave rear-wheel-drive edition is supposed to be situated at the top of the range with a string of high-end features that’s never before offered on a Cadillac. It’s a true innovative rendition of the 2003 concept which also consists of the newest in crash avoidance apparel and safety technology, all embedded in its new Cadillac parts.

The V12-powered flagship fundamentally matches two of the company’s 60-degree 3.6-liter V6 engines on a common crankshaft. It is a V engine joined by 12 cylinders. The V12 will include direct injection, cylinder deactivation and a tech-heavy automatic gearbox which has that assurance of high-performance power and fuel economy.

Bob Lutz, a longtime proponent of a luxury grand touring sedan for Cadillac and also GM’s global product vice president verifies development of the V12. He reportedly considers the model important to expanding the brand’s heritage as well as providing it with a more worldwide stance that’s capable of weaving through the key world automotive markets. Well, we just have to wait for an announcement on whether Lutz can convince GM’s bigwigs to put the Cadillac into production.

The V12 engine allows driving refinement in a luxury car, in a racing car; the rotating parts can be made much lighter and thus more responsive, since there is no need to use counterweights on the crankshaft.

In a large, heavy-duty engine, the V12 can run slower than smaller engines thus prolonging engine life. And there’s nothing more fitting for this engine than to take on Cadillac’s powertrain parts. The new Cadillac is uncertainly due to be revealed in 2009.

BMW has leaked information about the release of the new M3 engine that’s fitted in the BMW’s M3 Series. It seems like the compact sports car’s powertrain parts of the new engine will be quite a tour de force.

The new engine will be a V8 that’s for sure. Its significant particulars adhere to its performance coupe stakes. Sources have claimed that the BMW M5 is equipped with a V10; a meager six-cylinder powerplant is no longer adequate enough for the M3. So BMW’s engineering team hastily but meticulously snipped off one engine bank from the V10 and voila! A new and blazing V8 powerplant is born.

The M3 V8 engine is one powerful unit. The engine bay is equipped with four liters running on 420 horses with a 295 pound-feet maximum torque at 3,900 rpm. Also, 85 percent of torque is available from just 2,000 rpm which will probably be enough to thrust the M3 to 60 mph neck-snapping acceleration speed in just a couple of six seconds.

Though BMW has not yet explained the preliminary number specifications yet, they have unveiled the technical cues of the engine. It is made of alloy composite that carries only a total of 445 pound. Its features included are the variable camshaft control, upgraded MSS60 engine control unit for optimum coordination of all engine functions, double VANOS valve lift system (perfects the cylinder charge cycle), eight individual throttle butterflies for each cylinder (a technology commonly used in motorsport), Brake Energy Regeneration with alternator control (which ensures intelligent engine current management), innovative exhaust system optimizing cylinder charge, flow-optimized air intake and an outstanding Ion flow technology.

BMW is known for its powerful engines and this new V8 M3 engine will be added to its list of high-geared engine powerplants. The M3 is the perfect choice for fitting it with its brilliant M engine. With its spacious interior, sculpted surface and combination of power and sophistication, BMW pushes the boundaries of sports driving pleasure, offering the ultimate motoring thrill.

Beneath the 2008 Hummer H3’s gritty expression comes a 5.3-liter V-8 engine. Hummer engineers have propped in a Chevy Silverado V-8 and calling the resulting monster the H3 Alpha. Its powertrain parts constitute 259 ponies with an aluminum block. Maximum torque rating revs up to 317 pound-feet mated with a four-speed automatic gearbox allowing the H3 Alpha to haul up to 6,000 pounds and a four-wheel drive.

This is the second in a series of Alpha models churning off the H2 and H1. The H3’s not actually designed for a large V-8 but GM reconstructed the H3’s front end to accept its 5.3-lite V-8. The front end is also fitted with a new steering rack which according to Hummer “delivers a better steering feel and off-road capability”. The H3 Alpha is the first Hummer to be engineered in a juxtaposed venture with GM’s performance division.

Among the Hummer H3 Alpha’s vehicle alterations include a cast-iron front differential, new engine mounts, retuned suspension 16-inch chrome wheels and rims and a 4.10:1 rear axle ratio.

Like all 2008 H3 editions, safety components are upgraded for most road users’ convenience. It consists of side curtain bags, stability and traction control, tire pressure monitoring system. H3 Alpha owners can opt for both a rearview camera and a navigation system.

The new model will be showcased at the 2007 New York Auto Show.

Nissan Motor Co. has done it again with a new engine up their working sleeves. The new engine technology delivers power, fuel efficiency and low emissions while matched by Nissan’s newly developed Variable Valve Event and Lift (VVEL) and continuous valve timing control (C-VTC).

Let’s take a peak at its high-powered engine performance:
• Higher fuel efficiency - the system controls air intake at the intake-valve instantly before it enters the combustion chamber. In the low and medium rpm ranges, intake-valve lift is kept low to reduce camshaft function and caters to a whole fuel efficiency improvement.
• Better response - controlling air intake at the intake-valves progresses speed response by allowing more dense air into the cylinders from the start of the acceleration.
• More Power - low rpm range: intake-valves open for a shorter period, preventing blowback of the air-fuel mixture and advancing torque. High rpm range: greater intake-valve lift allows increased air intake to deliver greater torque outputs.
• Cleaner emissions - intake-valve timing is optimized on startup when the engine is still cool to rapidly boost the temperature of exhaust gases and more quickly activate the catalytic converter. Hydro-carbon emissions are minimized in the low-to-medium range by keeping intake-valve lift low, speeding intake flow and dispersing the fuel into a finer mist, resulting in more efficient full combustion.

The new engine technology has been creating much hype among car buyers and Nissan fans. Actually the first product that will include the VVEL technology is the Infiniti G37 coupe, set to be released at the upcoming New York Auto Show this April.

The VVEL technology will be made available globally to the general public through Nissan and Infiniti product lines and accessories. Nissan Motor Co. has planned to integrate the VVEL system which harbors up to a 10% reduction in CO2 emissions greenhouse gases and fossil fuels. The VVEL system will be wedded on most of Nissan parts and products starting from FY07 under the Nissan Green Program in 2010. While undertaking under the green-schemed program, Nissan has also took into consideration the development of gasoline-powered engines also to be released by the year 2010.
