J.D. Power study sees new car dependability problems increase for first time since 1998

For the first time since 1998, J.D. Power and Associates says its data shows that the average number of problems per 100 cars has increased. The finding is the result of the firm's much-touted annual Vehicle Dependability Study, which charts incidents of problems in new vehicle purchases over three years from 41,000 respondents.
Looking at first-owner cars from the 2011 model year, the study found an average of 133 problems per 100 cars (PP100, for short), up 6 percent from 126 PP100 in last year's study, which covered 2010 model-year vehicles. Disturbingly, the bulk of the increase is being attributed to engine and transmission problems, with a 6 PP100 boost.
Interestingly, JDP notes that "the decline in quality is particularly acute for vehicles with four-cylinder engines, where problem levels increase by nearly 10 PP100." Its findings also noticed that large diesel engines also tended to be more problematic than most five- and six-cylinder engines.

TMG's super Lexus LS Sports 650 gets track tested

The people at Toyota Motorsport GmbH have been responsible for the Japanese automaker's motorsports efforts since the 1970s, but since Toyota pulled out of Formula One after the 2009 season, the tuning shop has been developing a super sedan based on the Lexus LS called the Sports 650. Details on TMG's first road car have been scarce, but XCAR was recently invited to drive the 641-horsepower Lexus on track.
Here's what we know: the Sports 650 has enough power to sprint to 60 miles per hour in under four seconds, tops out at 199 mph, weighs over two tons and utilizes LFA brakes. Oh, and its twin-turbo V8 bellows like an AMG V8. That last part isn't surprising when considering TMG could become Toyota's in-house tuning arm - like AMG is to Mercedes-Benz. As for the bespoke body kit, fender flares and stacked exhaust pipes? They fit the car well and even remind us a bit of Lexus' other high-performance sedan, the IS F. Currently there are no plans for the Sports 650 to be made into a production car, but we doubt TMG is devoting this much effort developing the LS into a road-rocket for nothing.
Check out XCAR's video below to see the AMG-fighter wrung out on track, and then ponder what could be if TMG were let loose to fiddle with other cars in Lexus' lineup. Now that's something we could get used to!

2018 Lincoln Navigator vs luxury SUV rivals: How it compares on paper

The all-new 2018 Lincoln Navigator is an impressive, luxury-lined beast. However, while its Black Label interior stood out most during our first drive of the new Navigator, it also seemed pretty clear that much of this full-size SUV was superior to the competition in a number of fundamental ways. Its Raptor-sourced 3.5-liter V6 had class-leading power for one, and its third-row seat seemed as spacious and comfortable as its rivals' are cramped and barely usable. To search for your next new vehicle, try Autoblog' s Car Finder. Yet, I wanted to take a closer look at how the Navigator fully compares on paper to its competitors - especially the Cadillac Escalade with which it most directly competes. The below spreadsheet should tell the whole story, but as you can see, there's an awful lot of class-leading green highlighter in the Navigator's column. The cargo volume and third-row legroom numbers are particularly telling, with the latter actually going up to 42.3 inches when you slide the second-row fully forward. Now, a few things to note about the above spreadsheet. The GLS-Class is also available as the GLS 550, which boasts a 4.7-liter V8 that just comes up short to the Navigator with 449 horsepower but has to deal with only 5,578 pounds. Its $94,950 price tag is comparable to the Navigator Black Label. Much of the LX 570's information is also applicable to the Toyota Land Cruiser, which, badge aside, could certainly be considered a member of this segment given its feature content and still-hefty price tag. It has better ground clearance and approach/departure angles than its Lexus sibling, along with an as-indicated lower price. Much of the Escalade's information also applies to the GMC Yukon Denali, while the Infiniti QX80 is applicable to the Nissan Armada.
