Cadillac has released full details of a new Twin-Turbo V6 coupled with an 8-speed gearbox. The powertrain will be introduced with the all-new 2014 Cadillac CTS midsize luxury sedan debuting next week at the New York Auto Show.
The Cadillac Twin-Turbo V6 is the most power-dense six-cylinder engine in the midsize luxury segment – a 3.6L with 118 horsepower per liter (88 kW/liter).
“The new Cadillac Twin-Turbo brings a new dimension of technologically advanced performance to the all-new 2014 Cadillac CTS sedan,” commented David Leone, executive chief engineer.
“Delivering power and sophistication, it marks another large step forward in the product-driven expansion of Cadillac.”, he added.
The power is 420HP (313 kW) and 583 (430 lb-ft) ot torque at 2,500RPM. The engine has 15 % greater power density than BMW 535i’s turbocharged 3.0 liter twin-turbocharged engine. However, we need to mention that BMW has introduced this engine many years ago, when General Motors didn’t have slightest idea, how to create super power-dense engines.
The new CTS will accelerate to 60 mph (96 km/h) in 4.6 seconds and has a top speed of 274 km/h (170 mph).
The new Cadillac Twin-Turbo will expand the performance envelope of the upcoming 2014 CTS midsize luxury sedan, launching this fall in the United States. The engine will also will be offered in the 2014 XTS large luxury sedan this fall.
The new engine is a comprehensive upgrade on the 60-degree, 3.6L DOHC V-6 offered in today’s SRX, XTS and ATS. However, almost every component is unique. New features include:
- All-new cylinder block casting
- All-new cylinder head castings
- Strengthened connecting rods
- Machined, domed aluminum pistons with top steel ring carrier for greater strength
- 10.2:1 compression ratio
- Patented, integrated charge air cooler system with low-volume air ducts
- Two turbochargers produce more than 12 pounds of boost (80 kPa)
- Vacuum-actuated wastegates with electronic control valves
- All-new direct injection fuel system
- Tuned air inlet and outlet resonators, aluminum cam covers and other features that contribute to exceptional quietness and smoothness.
The 2014 CTS sedan will also feature the naturally aspirated 3.6L V-6 rated at 321 horsepower, as well as a 2.0L turbocharged engine rated at an estimated 272 horsepower.

Nurburgring is up for sale, because of the financial problems. The entire race track as well as all structures on the area.Jens Lieser, state-appointed liquidator has confirmed The Ring is on the market. For now, there is no information whether it will be sold as a whole or in pieces. For now, there are five to ten potential buyers of the race track. They are willing to pay a rumored selling price around 125 million EUR.The motorsports complex is around the village of Nürburg, Rhineland-Palatinate, Germany. It is located about 70 km (43 mi) south of Cologne, and 120 km (75 mi) northwest of Frankfurt. It features a Grand Prix race track built in 1984, and a much longer old “North loop” track which was built in the 1920s around the village and medieval castle of Nürburg in the Eifel mountains. The north loop is 12.8 miles (20.8 km) long and has more than 300 meters (1,000 feet) of elevation change from its lowest to highest points. Jackie Stewart nicknamed the old track “The Green Hell,” and it is widely considered to be the most demanding and difficult purpose-built racing circuit in the world.
Callaway has announced the 2014 Chevrolet Corvette Stingray AeroWagon. The Shooting Brake version of the sports car is already available and Callaway can build it for an additional $15,000.The rear of Corvette C7 is going to have carbon fiber structural components made using Callaway’s in-house Resin Transfer Molding process.It is powered by a 6.2 liter V8 with 450HP (335 kW) and 610 Nm (450 lb-ft) of torque. 0-100 km/h in 4 seconds. We expect some serious tuning of this power unit, so it can be able to reach top speed of over 322 km/h (200 mph).2014
