2014 Cadillac CTS is Put to the Test at Nürburgring



One of the Toughest Tracks in the World and Cadillac Aces it.

Cadillac validated its brand-new 2014 CTS midsize luxury sedan and power-packed CTS Vsport at the world’s most-demanding test track – Germany’s Nürburgring – and recorded lap times to enhance the nameplate’s reputation as a driver’s car.

Notably, the 2014 CTS Vsport, featuring Cadillac’s first  Twin-Turbo engine and eight-speed transmission, recorded a lap time of 8:14.10, almost six seconds faster than the first generation CTS-V recorded 10 years ago with a larger V-8 engine.


Nürburgring validation certified that all CTS suspension packages are capable of handling the extreme conditions and unlimited speeds of Autobahn driving. CTS development included Autobahn and track calibrations of the steering system, shock absorbers, chassis controls and powertrain cooling.
“The Nürburgring’s extreme conditions allow us to push cars to the limits of stability, steering, braking, ride and handling,” said Dave Leone, CTS executive chief engineer, Performance Luxury Vehicles. “The new CTS models had a lot to live up to considering the nameplate’s history of outstanding performance, and we were not disappointed.”

Measuring 12.9 miles (20.8 km) and including some 154 turns, the Nürburgring’s Nordschleife (“north loop”) is widely considered the world’s most-demanding course for vehicle validation. Cadillac vehicle dynamics performance engineer Kevin Zelenka and Jeff Grabowski drove full production models of CTS and CTS Vsport with no performance modifications, validating all-new 2014 CTS sedan that goes on sale this fall.

“The new CTS was an absolute riot to drive on the Ring,” said Zelenka. “It’s more athletic and refined, and the Vsport proved extremely capable. If a car performs well on the Ring, it will perform well on any road in the world.”

The CTS has been the centerpiece of Cadillac’s portfolio for more than a decade. The third-generation CTS is one inch lower, five inches longer and more than 200 pounds lighter than its predecessor. The new car also has lower curb weight, greater structural stiffness and more horsepower than its primary competitors.
The all-new CTS is engineered from the ground up to deliver a driving experience that combines sport-tuned handling with world-class comfort. Its segment-exclusive Magnetic Ride Control and electronic limited slip differential constantly monitor rear-wheel rotation to ensure optimal handling in a variety of road conditions.
The 2014 CTS standard model will start at $46,025, including $925 destination. Three collections of option packages – Luxury, Performance and Premium – will be offered with either the 2.0T turbocharged four cylinder or 3.6L naturally aspirated V6 engine in either rear- or all-wheel drive. The CTS Vsport model starts at $59,995, including $925 destination, and features the new Cadillac Twin-Turbo 3.6L V6 (420 hp) in RWD only with an eight-speed transmission.

2013-17 COPO Camaro: Strictly Business

The COPO (Central Office Production Ordered) Camaro is the rarest of all the Camaros that is available to the public. It was first introduced in 1969 and was built by General Motors for the sole purpose of drag racing. The ideal behind it was to bring competition to the NHRA (National Hot Rod Association) drag racing circuit. Up until 1969, the Ford Cobra Jets and Dodge HEMIs dominated the Stock and Super Stock circuits because the Camaro did not meet NHRA rules and regulations and was unable to race. So to fix that problem, GM decided to make sure the COPO Camaro would be produced and delivered to the consumer with every NHRA rule and regulation followed.




2013 Special Edition COPO Camaro Convertible 

A special edition convertible version of the COPO Camaro was auctioned off at the Barrett-Jackson Auction in 2012. General Motors managed to bring in $400,000 dollars for the first ever sold 2013 Inferno Metallic Orange Camaro with all proceeds going to help the American Heart Association.

Now, if you were someone that wanted to get your hands on one of these rare Camaros, you would not have to shell out $400,000 dollars, but you should expect to at least shell out about $89,000 dollars, that is if you are someone who is lucky enough to order one before there all gone.

2018 Trans Am and Firebird Speculations

 

2018 Trans Am-Firebird

There is a lot of fluff about if GM will ever come back with a Trans Am or a Firebird, but that is just what it is, fluff. If GM does decide to bring it back there would be a lot of car enthusiast very happy with their decision. But if they are planning on making this type of move, they are defiantly keeping a very tight lid on what they're going to do and when.


There is one fact that has been made very clear by GM. If they do bring back the Trans Am and Firebird, they will not be bringing back the Pontiac line. All production would be under the authority of GM and the Pontiac name would not even be used for the very well loved sports cars. One last thing that is pretty well-known about the situation is that they would probably be produced alongside if not in the same factories as the Camaros, and would be sold at Chevrolet dealerships where Camaros are sold.


Build Your Own Trans Am/Firebird

If you are someone who does not want to wait for GM's decision and you must have one, there is an alternative. Companies like Trans AM Depot and a few others that can be easily found on the Internet, build awesome looking prototypes of Trans Ams, Firebirds, Hurst and Firehawks that can be customized personally and purchased by private owners.


The process is really cool, brand new Camaros are purchased than ground effects, bumpers, spoilers interior and whatever else that needs to be replaced is replaced with prototype parts for the unique styling that replicas what a new Trans Am would probably look like if GM was to start making them again. The nice thing about these projects are that they're made from new Camaros, that should be enough to ensure that the cars that you will be purchasing are a great American Motor product.

2015 Cadillac Escalade

Image result for 2018 escalade

The Cadillac division of General Motors' has announced that it will unveil its next-generation Escalade SUV in New York City on October 7, it will be going on sale in 2014 as a 2015 model. According to Auto Blog who's reporters have caught glimpses of the new Cadillac, the Escalade is anticipated to have a much more aggressive and more flashy look than that of its current model. It will have longer lines, thin headlines and an egg-crate grill, but the inside is where the real upgrades are expected to take place.



The powertrain is expected to go a little bit like this: At launch, a 6.2-liter V-8, rated at roughly 420 horsepower and 450 pound-feet of torque should be offered. But you can expect more powertrain options to be offered further down the road.

When it comes to the interior it looks like the new cabin is where Cadillac will set itself apart as a luxury brand. The Escalade boast a CUE infotainment system accessorized with a large touch screen and roomy interior, like always, but this time they will implicate a much needed electronically motorized 3rd row. 

Not unveiling the Escalade at the Texas State Fair is the first time for a vehicle of it's kind, but GM seems confident that New York City is the place that is most appropriate for the launch when considering the Cadillac’s customary consumer base. And that clientele seems to be pretty happy with what the Cadillac has had to offer so far, demonstrated by the fact that Escalade sales are only down 5 percent this year even though consumers are aware that a new model will soon be launched.

Despite the current Escalade debuting back in March 2006, sales for the SUV, including its extended-length ESV and pickup-version EXT variants, have stayed roughly flat in 2013. But Cadillac has still sold more than 12,500 Escalades through July, or nearly as many as the Infiniti QX56/QX80 and Land Rover Range Rover combined. Escalade sales are nearly triple the also-aging Lincoln Navigator, which at one point was its most direct competitor. The sales lead may eventually diminish as the Escalade EXT and the Chevrolet Avalanche sibling won't likely return . Through July, the EXT still accounted for 10.6% of all Escalade sales.

Like Ford, now that the U.S. automaker has been able to resurrect such significant success with its fuel-efficient compact cars and full-sized pick-up turcks, GM is ready to turn its attention to its luxury brands and make sure its recent progress is sustainable across the board. The Cadillac ELR is also poised to go on sale in early 2014, and reflects the brand’s future design strategy with its sleek lines, aggressive stance, and a crisp, modern look. The ELR is also a hybrid vehicle and features a 1.4-litre engine, good for about 84 horsepower, and an electric motor that provides its 295 pound-feet of torque.

Cadillac's Turbo Technology

Where is Cadillac Today?                        


Cadillac has been a leading luxury auto brand since 1902. Today Cadillac is growing globally, driven by an expanding product portfolio featuring dramatic design and technology. More information on Cadillac appears at www.cadillac.com. Cadillac's media website with information, images and video can be found at media.cadillac.com.


 

No More Turbo Lag

Turbocharging increases power and performance with efficiency, but the delay in the delivery of power – known as “turbo lag” – has historically been its key limitation.

That’s about to change.

Cadillac’s first-ever Twin-Turbo, available on the 2014 CTS Vsport midsize luxury sedan and XTS Vsport full-size luxury sedan in the U.S. this fall, kicks turbo lag to the curb with a unique combination of smaller turbochargers, top-mounted throttle body and shorter air pathways.

The Cadillac Twin-Turbo V-6’s patented air flow design, which eliminates circuitous heat-exchanger tubing, makes the most of engine packaging efficiency to improve torque response time over other air flow designs.



Rated at 420 horsepower on the all-new 2014 CTS Vsport and paired with Cadillac’s first eight-speed transmission, the Twin Turbo is one of the most power-dense engines in the midsize luxury sedan segment, rated at an SAE-certified 420 horsepower and 430 lb.-ft. of torque.

Air flow routing volume is reduced by more than 60 percent when compared with a conventional design that features a chassis-mounted heat exchanger. The water-to-air cooler system achieves more than 80 percent cooling efficiency with only about 1 psi flow restriction at peak power for fast torque production.

“By creating a very short path from the turbos to the throttle body, the compressors are able to draw air directly from the inlet box and send pressurized air through the intercooler immediately,” said Richard Bartlett, Cadillac assistant chief engineer for the 3.6L engine. “This gives the driver a more immediate feeling of power on demand.”

Using two smaller turbochargers rather than a single larger turbo also helps ensure immediate performance because smaller turbochargers spool up quicker to generate horsepower-building air pressure that is fed into the engine. An integrated charge air cooling system also contributes because the compressors blow through very short pipes up to the intercooler.

The single centrally located throttle body atop the engine controls the air charge from a pair of turbochargers after the temperature is reduced in the intercooler. This design fosters more immediate torque response and reduces complexity by eliminating the need for a pair of throttle bodies.

Together smaller turbochargers, top-mounted throttle body and shorter air pathways help sustain peak torque over a broad range – 1,900 to 5,600 rpm – for a confident feeling of power in almost all driving conditions, such as accelerating or overtaking traffic on the highway.

“The Cadillac Twin-Turbo intercooler design builds on our experience with the 6.2L supercharged engine used on the current CTS-V Series,” Bartlett said. “That means more performance for drivers without sacrificing efficiency.”

Street Racing: Not Worth It!






Growing up I spent many years at the Drag Strip, but when I got my first car (71' 455 Buick Skylark, low 12's in the quarter-mile) in High School I found a new way to skip school and hang out late at night. Throughout all my drag racing troubles I managed to almost kill myself and an old lady while skipping auto class to drag race a friend. I also got caught in a drag racing sting in Detroit a few years later that cost time off of work and a fortune in my pocketbook. Add that in with the mass amounts of traffic tickets and the stupidity adds up.  

As young adults, we were out of control. It all seemed like fun and games, but when I recently lost a friend from street racing I realized that no one was invisible and this might be as dangerous as I was warned.







My advice to anyone out there, settle it at the Drag strip. 

 Advantages
  • No reason for fighting because you can't cheat. (Leave Your Guns at Home)
  • Professional safety help is there for the sole purpose of a racing accident. And you won't have to worry about people running away from the accident to stay out of trouble when you're in need of help.
  • Doesn't cost that much to race, and a speeding plus drag racing ticket costs much more.
  • You're more likely to stay alive and not injure innocent people.
  • And usually, people are mostly friendly.
