Ford Motor Company’s recent introduction of their twin-turbo 3.5L V6 has brought the industry limelight to high tech, forced induction V6 powertrains. Rumors of General Motors joining in on the turbocharged V6 arena have been around for several years now, however GMI has confirmed that The General really will be joining Ford in the high tech turbo bandwagon.

According to GM engineering sources, GM is currently working on a twin-turbo 3.0L V6. Development on the new engine is so far along that it has a RPO code of “LF3.” The naturally aspirated 3.0L debuted in several 2010 products with direct injection and has the code “LF1.”

GMI was not able to obtain projected power ratings on the new engine, however output is very application specific under new SAE testing rules. Sources did say to expect the engine to rival Ford’s EcoBoost 3.5L.

The new 2011 Ford Mustang V6 will serve as the pace car for NASCAR’s Food Land 500 at Bristol International Speedway. What’s special for this model – this will be the second time a Mustang has paced a NASCAR race this year after the new 5.0-liter Mustang GT led the pack at the Daytona 500 in February.

Mustang is not the most powerful muscle car, serving as pace car, but specialists think that the V6 model will be capable of carrying out its duties thank to its new 3.7-liter engine – the ‘Stang has 305 horsepower and 280 pound-feet of torque. You can see the new 2011 Mustang V6 pace car in action by tuning into Fox this Sunday at 1:00 pm EST.

Maybe a 4-door Corvette is going to be designed. According to a report by Wards Automotive, it is possible.

If we take a look at another great car – The Porsche Panamera, we can see a 4-door successful selling automobile. With creating a 4-door Corvette, Chevrolet could introduce a higher-volume V6-powered version. This idea is not new – it has been debated in the past with the 2-door Corvette as a way to attract female buyers and those less interested in the car’s V8 performance and more its stylish good looks.

The guys from Autoguide think that it may help GM reduce costs, increase profitability and offer a unique product. Would it devalue the Corvette name? Probably not, considering the Panamera doesn’t seem to have hurt the Porsche 911. Would it be hideous? Quite possibly. But again, that hasn’t seem to hamper sales of Porsche’s new 4-door.

Actually this is a Roush 427R, but the special edition, announced today by Paul Miller Ford, boasts only visual enhancements. However this Stang looks awesome with its new front fascia and front splitter, a rear fascia, side splitters and custom blue and black suede seating accents. The paintjob is great, too – jet black with University of Kentucky True Blue stripes. The power unit is the well-known 4.6l engine boosted with the help of the Roushcharger supercharger system.

“The inspiration for the outer appearance and the color scheme came from a Bill Keightley jersey that was given to me last year,” J.P Miller, General manager for Paul Miller Ford says. “It just seemed to be the perfect fit for this project.”

Only five copies of the Coach Cal Edition will be made and the sixth one is goingo to be owned by John Calipari (Coach Cal). According to kentucky.com, the car will be priced at a bit over $71,000, with a Mustang GT based version to retail for less than $40,000.

It seems that Chrysler’s upcoming 6.4-liter V-8 gasoline engine will only be available for the SRT vehicles and not Ram Heavy Duty pickup trucks. Joe Veltri, Chrysler vice president of product planning, said “it’s designed for performance, not low-end torque. It’s designed for off-the-line 0-to-60 times.”

He also added “it’s a struggle to recrank that engine to make it a truck engine.” As we can see, Chrysler maybe needs a gas engine with more horsepowers than the current 383 horsepower, 400 pounds-feet of torque 5.7-liter Hemi V-8 used in the Ram HD trucks.

Actually, in the heavy-duty segment between gasoline and diesel engines there is a tendency – from 75%/25% to 70%/30% today and maybe 60%/40% in the future (gas/diesesl). And the price of the diesel engines is rising up.

For all of you, who live in Australia – GM’s decision a few days ago will not affect Performax’s plans to import, modify and sell Camaros.

According to Performax, about 250 hours of work per Camaro are needed for the left-hand drive to right-hand conversion. All these modifications inolve changes to steering, emissions equipment, lighting, air-conditioning and ventilation and body – all parts used by Performax are ISO-accredited.

“Performax International was first in Australia with the Camaro and we have achieved factory-standard engineering and finish quality in producing right-hand drive versions. Whatever any other importer decides to do or not do, Performax is proud to have the first and best RHD Camaros and we expect plenty will be finding their way to owners around Australia”, said Performax International General Manager Glenn Soper.
