New York • Although many European automakers debuted their new vehicles in Detroit in January or in Geneva in March, some chose to make their world premieres here at the New York International Auto Show.
Following are the highlights:

The powerful new 4.0-litre twin-turbocharged GTC V8 features 500 horsepower and peak torque of 487 pound-feet.
BENTLEY
Bentley’s new Continental GTC V8 convertible made its official debut here to one of the largest crowds at the show.
The powerful new 4.0-litre twin-turbocharged GTC V8 features 500 horsepower and peak torque of 487 pound-feet. With a new close-ratio eight-speed automatic transmission, the GTC sprints from zero to 100 kilometres an hour in just five seconds and has a top speed of 301 km/h. And, according to Bentley, the new V8 Continental delivers a 40% improvement in fuel efficiency and CO2 emissions.
The Continental GTC V8 and its GT V8 coupe counterpart feature a state-of-the-art, all-wheel-drive system employing an advanced Torsen differential and a 40:60 rear-biased power split.
MERCEDES
Mercedes had three world premieres at the show — the new-generation GLK, shown at top, the all-new GL and the new SL 65 AMG.
The new GL features space for up to seven passengers and safety innovations such as crosswind stabilization, Steer Control, self-levelling and Collision Prevention Assist, which are all standard. Active Lane Keeping Assist and Active Blind Spot Assist are also available on the GL-Class.
The new GL 350 BlueTec 4Matic offers a 20% reduction in fuel consumption, with a fuel economy rating of just 7.4 litres of diesel per 100 kilometres, according to Mercedes. Fuel consumption for the 408-hp GL 500 4Matic BlueEfficiency drops by 18%, says the automaker.
Mercedes’ smaller SUV, the cute and compact GLK, gets a new look and upgraded equipment. The redesigned exterior features the design language of the automaker’s sedans, which is not a bad thing. In fact, the attractive GLK now looks like a sedan as much as it drives like one while retaining all the amenities of a sport-utility vehicle.
Inside, the GLK features new equipment and redesigned trim elements, along with state-of-the-art assistance systems and comprehensive BlueEfficiency measures such as the Eco start/stop function.
The BlueTec diesel exhaust after-treatment system is also available for the GLK for the first time. The GLK 250 BlueTec 4Matic features 204 hp, making it the most powerful four-cylinder diesel engine in the SUV world, according to Mercedes. It consumes just 6.1 and 6.5 litres of diesel per 100 km on the highway and in the city, respectively.
The new SL 65 AMG has a 6.0L V12 biturbo engine featuring a whopping 630 hp and 738 pound-feet of torque! The all-aluminum body is 170 kilograms lighter than its predecessor. Only 45 of the special-edition SL 65 AMGs have been created for the 45th anniversary of AMG, so you’d better order one soon.

PORSCHE
Coming a day before Ferdinand Alexander Porsche, grandson of the company’s founder, died at age 76, the automaker unveiled its Cayenne Diesel.
Designer of the original 911, F. A. Porsche died April 5 at his home in Salzburg, Austria.
When he first started at the company, working with his father and grandfather, the young Porsche probably never envisioned an SUV being built by the family firm.
But this is what the people want now and so Porsche moved with the times to create its Cayenne in 2002.
Ten years later comes the diesel version, which will be the first diesel-powered Porsche in Canada when it arrives in September.
The 2013 Cayenne Diesel features a 3.0L V6 turbodiesel engine generating 240 hp and 406 lb-ft of torque. According to the automaker, the SUV accelerates from zero to 100 km/h in just 7.6 seconds and has a top speed of 218 km/h. The diesel-powered Cayenne is expected to have a 30% improvement in fuel economy over its gasoline-engine sibling, says Porsche.
Pricing for the new Cayenne Diesel in Canada will start at $64,500.
