Hennessy wastes no time in supercharging the 2015 Cadillac Escalade

The ink is still drying on the all-new 2015 Cadillac Escalade sales brochures, but that hasn't stopped Texas-based Hennessey Performance (HPE) from leaping out of the gate with its own high-performance variant. In stock form, the big fourth-generation Cadillac flagship arrives with a new small block naturally aspirated 6.2-liter Ecotec3 V8 delivering 420 horsepower and 460 pound-feet of torque. Fresh out of the showroom, the 5,900-pound SUV will sprint to 60 mph in 5.9 seconds.
While that is plenty fast for some owners, others don't want to be shamed by a 550 horsepower Mercedes-Benz GL63 AMG or a 510 horsepower Land Rover Range Rover Sport - both will leave the stock Escalade at a stoplight.
The team at HPE has come to the rescue with its HPE550 supercharger upgrade, which includes a belt-driven supercharger, air-to-water intercooler, recalibrated engine management software and a three-year/36,000 mile powertrain warranty. With 6 psi of boost, the direct-injected 6.2-liter is tuned to deliver an impressive 557 horsepower and 542 pound-feet of torque - gains of 32 percent and 18 percent, respectively, over stock. Although HPE isn't releasing performance figures as of yet, our math says that should be enough power to put the two Europeans in the Cadillac's rearview mirror. The company also offers a set of 20-inch lightweight H10 forged monoblock wheels, to further improve performance.

Cadillac CTS Vsport laps the N"urburgring in 8:14.10 [w/video]

You don't have to be German to test your car at the Nürburging. You just have to be serious about beating the Germans on their own home turf. That's why Nissan tests its GT-R at the Nordschleife to challenge the Porsche 911, and why Cadillac - which is no less serious about putting up a fight to German performance sedans - has returned to the 'Ring once again with its latest.
This time it's the turn of the new CTS Vsport, the sportier version of Cadillac's new mid-range sedan that aims to bridge the gap until the arrival of the next CTS-V. So how'd it fare? At the end of what we're sure was an exhaustive test session, the new CTS Vsport clocked a time of 8:14.10.
To put that into context, General Motors points out that the time places the new sedan six seconds ahead of the first-gen CTS-V, whose 400-horsepower V8 engine was actually less potent than the Vsport's new 410hp 3.6-liter twin-turbo V6. That's still a good fifteen seconds slower than the outgoing CTS-V that clocked a 7:59 in 2009 with its 556hp supercharged V8, but only a second behind the E60-generation BMW M5 with its high-revving 500hp V10.

GM slashes prices in China as sales falter

Buying a vehicle from General Motors' stable of brands might be a lot cheaper in the near future – at least for customers in China. The effort comes as GM hopes to keep sales there growing, and the decision alludes to yet another sign that the Asian country no longer has the booming auto market of past years. GM and its Chinese joint venture partner SAIC are slashing prices by as much as the equivalent to $8,700 on 40 models from Buick, Chevrolet, and Cadillac, according to The Detroit News. Across all of automaker's nameplates, the overall sales dipped in China in April by 0.4 percent to 258,484 vehicles. Among the drops, Buick was down 8.5 percent, and Chevy shrunk 5.6 percent. Caddy's numbers increased 4.6 percent for the month, though. Buick remains a popular brand in the minds of Chinese consumers, but according to The Detroit News domestic automakers there are starting to eat into the dominance of foreign companies in the market. The country remains important for GM, though. Late last year, it outlined a future strategy that included China as a major pillar, including a $14 billion investment to build five new factories and boost sales.
