Chrysler SRT Viper

According to latest Chrysler Group LLC press release “The Snake Returns to Chrysler Group’s Conner Avenue Assembly Plant” Dodge will no longer give its name to Viper – it is going to be forwarded to SRT division and will be called 2013 SRT Viper.Conner Avenue will begin building the new 2013 Viper in late 2012, but employees began reporting for training and orientation this fall – nearly 150 jobs to return to Detroit.

Chrysler’s reborn Viper won’t make its public debut for about a month, but our illustrator has put together a highly detailed rendering of the new performance car that will help boost the profile of the company’s Street and Racing Technology division.

Set to become the first vehicle marketed under the SRT banner, the 2013 Viper has been a long time coming. Its Dodge Viper predecessor has been out of production since mid-2010, but a fifth-generation snake will debut next month at the New York International Auto Show.

Our illustration is based on information culled from a number of sources, one of which is rather unusual, to say the least. While information gleaned from insiders, including those few members of the public who have been allowed to see the car, and photos of cleverly disguised test mules form the basis of much of the illustration’s details, a leaked image of a Hot Wheels 1/64-scale toy car helped put the finishing touches on our rendering.

That Hot Wheels model made its way online last week when it was posted on a Viper forum.

We expect the Viper’s proportions to remain mostly unchanged, but its rear end is more aggressive and angular than the one seen on the last generation. As predicted by spy shots and previous reports, the car features a high-sculpted hood fitted with two big air vents.

Those vents will be needed as the SRT Viper is expected to arrive with an 8.7-liter V10 engine that will send over 600 horsepower to the rear wheels. Early rumors suggested the car would share some of its architecture with the voluptuous, if slightly un-engaging Alfa Romeo 8C Competizione, but SRT chief Ralph Gilles has been quick to dispel those rumors by stating that “The new Viper is not based on anything else.”

As previously reported, Chrysler is reopening its Conner Avenue Assembly Plant in Detroit to build the Viper. The automaker has offered jobs to all 150 workers it once employed at the facility, which it uses exclusively to hand-build Vipers.

“The next generation Viper will make its return to the product lineup in late 2012 as a 2013 model,” said SRT Brand & Motorsports President/CEO Ralph Gilles in a statement released to the media. “We’re extremely excited that our ultimate American sports car will continue to live on and be produced exclusively here in the Motor City.”

‎Porche 911 Carrera 4 GTS Cabriolet

Marking the second of the two new models introduced by Porsche in its ever-expanding 911 lineup, the 911 Carrera 4 GTS Cabriolet is the more aired-out version of the all-wheel drive Carrera 4 GTS.

Just like the Coupe, the Cabriolet model gains the powerful 408 horsepower 3.8-liter six-cylinder engine from the GTS rear-wheel drive models and adds in front-wheel drive as well, for a uniquely drop-top all-wheel drive experience.

As expected, the Cabriolet gains a few pounds over the sealed-top counterpart thanks to the mechanics of its convertible design. As a result, zero-to-62 mile per hour sprint drops slightly to 4.8 seconds when equipped with a six-speed manual transmission, and to 4.6 seconds if one opts for the Porsche-Doppelkupplungsgetriebe (PDK) seven-speed automatic transmission.

Like the Coupe, Porsche says fuel economy stays the same, which the automaker attributes to Porsche Intelligent Performance technology.

Porsche says that the 4 GTS is built with hardcore performance in mind. As a result, standard features include a crucial limited-slip differential with is incorporated into the overall performance of the all-wheel drive system.

In terms of cosmetic differences between other 911 models, the new Carrera 4 GTS Cabriolet comes with the expected unique badging on the doors and rear lid, as well as an additional reflective stripe between the taillights. Of course, the 4 GTS uses the same wide body found on other AWD models. Cosmetic variances continue with 19-inch black RS Spyder wheels with central locking and gloss-lathed rim flanges, wrapped in 305/30ZR19 tires out back.

Towards the front, one will notice the Porsche Sport-Design front apron with a black painted spoiler lip and matching black special side skirts.

As all GTS owners have come to expect, the interior is covered in swaths of black Alcantara covering the center panels, steering wheel, gearshift, handbrake, door handles and door storage box lid.

G-Power 2012 BMW M5 640-Horses

G-Power, the maker of some of the fastest and meanest tuned BMW models around, has presented its first take on the brand-new 2012 M5 sedan.

At the heart of G-Power's tune is BMW's 4.4-liter twin-turbocharged V8 engine that normally produces 560-horsepower and a peak torque of 680 Nm (502 lb-ft) from 1,500 rpm.

After the German company's engineers update the ECU and add a new custom exhaust system, the V8's output is lifted to 640-horsepower and 777Nm (573 lb-ft).

As a result, the M5 completes the 0-100km/h (62mph) sprint in 3.9 seconds (vs. the standard model's 4.4 seconds) and reaches the 200km/h (124mph) mark in just 11.9 seconds.

To improve handling, G-Power has fitted the M5 with the height-adjustable coil-over suspension "GM5-RS" with nine selectable settings for bound and rebound, along with a new braking system (396 mm discs with six callipers), and 21-inch alloy wheels wrapped around Michelin Pilot Super Sport tires (265/30 ZR 21 at the front and 305/25 ZR 21 at the rear).

G-Power noted that it is also working on a successor to the 800-horsepower M5 Hurricane RR, which is considered to be the faster sedan model in the world with a top speed of 372km/h (231mph).
