Weekly Recap: Automakers rethink the definition of luxury

Variety is the spice of life, but it's becoming a prerequisite for luxury carmakers in the ultra-competitive US market. The Detroit Auto Show was strong evidence of this reality. It's not enough to offer attractive and well-appointed cars and SUVs anymore. Luxury brands that want to be competitive need to invest in everything from high-powered supercars to clever hybrids. To be relevant, you need to be green and mean – and everything in between. As General Motors product chief Mark Reuss said after the reveal of the 640-horsepower Cadillac CTS-V: "We are not leaving anything on the table." He was speaking for Cadillac, but he might as well have been speaking for the luxury car market. The CTS-V debuted in Detroit about an hour after Lexus surprised showgoers with the reveal of the RC F GT3 race car and then announced ambitious plans to return to competitive racing. That almost overshadowed the fact Lexus had just revealed another potent addition to its growing F line, the 467-hp GS F.

Strong competition from all corners has forced automakers to refine and expand their lineups in ways unforeseen even a few years ago. Case in point: Mercedes-Benz finally has an answer to the BMW X6, rolling out the GLE coupe in Detroit. The X6, which blends coupe-like styling cues with some of the functionality of an SUV, debuted in 2008. Back then it was a punchline, but seven years and more than 260,000 sales later, the X6's success has compelled Benz to respond. Mercedes – one of the strongest proponents of diesel technology – also debuted the C350 plug-in hybrid sedan, which promises a range of 20 miles on electricity, though fuel economy figures were not announced. The car pairs Mercedes' well-received 208-hp turbocharged four-cylinder with an electric motor for total output of 275 hp and 443 pound-feet of torque. Meanwhile, Infiniti will add the Q30 hatchback to its lineup by the end of the year, new president Roland Kruger reiterated in Detroit. It's expected to be joined by a crossover variant, and the additions will help strengthen Infiniti in the United States and abroad. "While we're expanding our product line, we're also expanding our market reach," he said. That's something echoed by Jaguar executives, who are preparing to launch the brand's first crossover, the F-Pace, in 2016.

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.

Here is the Cadillac XT6 three-row SUV's interior

The Cadillac XT6 has once again been spotted by one of our spy photographers. Though the outside is still as buttoned-up as ever, our photographer managed to get close enough to see the completely uncovered interior. On the surface it looks more like the interior of the CT6 than the latest Cadillac model, the XT4, which is rather surprising. Specifically, the dashboard layout is nearly identical to the CT6's. It's a wide, sweeping dash, and the mid-section is dominated by a broad piece of trim that appears to be carbon fiber in this model. It likely can be replaced by wood, leather or a variety of other trims. The top part of the center stack is dominated by a large touchscreen with touch buttons surrounding it for driver's aids. Directly underneath are subdued air vents followed by the climate controls. These controls appear to have been lifted straight from the CT6 and feature touch buttons and a trio of toggle switches. The few places the dashboard deviates from the CT6 include how the XT6's fancy trim spans the full width of the dash, rather than giving way to some plain leather on the driver's side. This gives the whole dash a more upscale look. The dash also doesn't try to smash too many different materials and textures into one design. Overall, it all looks attractive enough, though we're a little disappointed to see a lack of physical buttons as we saw in the XT4. That being said, there are XT4-inspired elements in the XT6's interior. Most prominent is the scroll wheel down in the center console. We suspect the infotainment system will be effectively identical, so the wheel will similarly serve as a redundant means of controlling the infotainment system along with the touchscreen, voice commands and wheel controls. The shifter also seems to be the same as the XT4's. The XT6 exterior doesn't really reveal anything new. It still looks angular, and it still looks long enough to have a third row of seats. The introduction of this model will certainly give Cadillac a much more rounded lineup of crossovers from small to large, something the brand sorely needs. Related Video:
