2013 Infiniti IPL G Convertible

Infiniti rolled out the IPL version of its G37 Convertible at the Los Angeles Auto Show more than a year ago. The Infiniti Performance Line treatment logically mirrors that of the IPL G Coupe, meaning it receives both cosmetic and mechanical tweaks designed to raise the pulse of driving enthusiasts. Aside from the overstated aerodynamic styling components and huge exhaust tips, the cabin features special leather upholstery, aluminum trim and IPL badging to distinguish it from lesser siblings. Under the hood, the 3.7-liter V6 (VQ37VHR) has been recalibrated to deliver 343 horsepower - 18 more than the standard coupe - and 273 pound-feet of torque. The suspension has been upgraded with firmer spring and stabilizer bar rates, multi-piston sport brakes are fitted and 19-inch graphite-finish wheels wrapped with summer rubber are bolted on. There are only two exterior color choices (Moonlight White and Malbec Black) and two upholstery choices (Stone and IPL-exclusive Monaco Red). Everything sounds marvelous until someone reveals its as-tested $62,415 window sticker.
DRIVING NOTES
The three-section steel roof raises and lowers in a leisurely manner - give it about 30 seconds each way. While it is marvel to watch, the operation seems clunky, not fluid. Buttoned up, with all four windows closed, the cabin is comfortable. Wind noise is minimal and the front buckets coddle passengers in all the right places. While tight, those of smaller stature will find the two rear seats tolerable for short journeys (my kids never complained). Outward visibility is also very good for a convertible - no impeding B-pillar.

Infiniti Q50 steer-by-wire system took 10 years to develop [w/video]

Infiniti's Direct Adaptive Steering (DAS) is quite a novelty - the system employs no physical connection between the steering wheel and the front wheels under normal circumstances and instead relies on a computer, clutch and steering-angle actuator to guide vehicles down the road with input from the driver.
In our First Drive review of a 2014 Infiniti Q50 equipped with the system, we weren't overly impressed by the artificial feedback. But we can't help but be impressed with how long Infiniti spent on its development: a full 10 years, according to Autoline Daily in the video report below. A staggering 70 percent of the research and development time spent on DAS was devoted to getting the steering feel right, and unfortunately, our first impression suggests their results still leave something to be desired, as we found it lacked the sporty feeling a sport sedan should have.
The weight of DAS is comparable to that of a conventional steering system due to its complexity. For example, three ECUs are used in the first-generation DAS system to ensure there's never a loss of steering, but Infiniti is refining the technology and is working to simplify it to reduce weight. One day Infiniti hopes that only one ECU will be needed to control DAS. We just hope it doesn't take the Japanese automaker another ten years to get the steering feel right.

Is your new-car warranty good at the race track?

We've all heard the horror stories. Your buddy knows a girl that was dating a guy whose best friend's brother once broke his brand-new, recently purchased performance car while making runs at a drag strip or laps at a track day, and the manufacturer wouldn't cover the repair under warranty. True story? Urban legend? Complete crap? Yes, no, maybe. One thing's for sure: Automotive warranties have always come with caveats. In 1908, an ad in the Trenton Evening Times clearly stated: "All Ford Cars Guaranteed for One Year." Although it changed over time, by 1925 the Ford New Car Guarantee only covered 90 days on material and 30 days on labor, and it clearly stated that that there was "No guarantee whatever on Fan Belts, Glass, Bulbs, Wiring, Transmission, Bands, Hose Connections, Commutator Shells, Rollers, Spark Plugs or Gaskets." Whether or not Ol' Henry would pay to fix your Model T if you broke it shaving a tenth off your lap time at the local board track seems to be lost to history. We're guessing no. But what about today? Do new-car warranties in 2017 cover cars when they are driven on race tracks? We researched the warranties of 14 auto brands to find out, and the answer is yes, no, maybe, depending on the brand, in some cases the model, and whether or not your car is modified from stock. Acura has been out of the high-performance car game for a number of years, but jumps back into the party in 2017 with its hybrid-powered $173,000 NSX supercar. And Acura's warranty, as well as Honda's, clearly states that it does not cover "the use of the vehicle in competition or racing events." View 33 Photos So we asked Sage Marie, Senior Manager of Public Relations for Honda and Acura. "If the car is stock, the warranty covers it on a track just as it does on the street. No question," he told us. "However, if the car is modified, say with slick tires or other components that would put higher stresses on the vehicle's parts and systems, then we would have to investigate the circumstances further." Marie went on to say the same would be true for any Acura model or Honda vehicle, including the new 2017 Honda Civic Si. This became a common theme. Chevrolet actually started this practice with the fifth-generation Camaro on the high-performance ZL1 and Z/28 models.
