2014 Infiniti Q50S

Ten years ago, nearly to the day, I took delivery of a brand-new 2004 Infiniti G35 6MT. The sporty rear-wheel drive sedan, equipped with its throaty 260-horsepower V6, slick manual gearbox and limited-slip differential replaced my 2001 BMW 330i because the Japanese competitor touted a product that was roomier, better equipped, quicker and lower priced. The G35 trumped the German in nearly every measurable category - at least on paper.
The 2014 Infiniti Q50 is the direct descendant, albeit two generations later, of the car I owned a decade ago. It is dimensionally about the same size, but it has gained more than 300 pounds of mass thanks to numerous safety upgrades and technical innovations. The additional weight is largely dismissed by a larger and more efficient powerplant that delivers an additional 68 horsepower, a welcome arrival, but the manual gearbox that charmed enthusiasts has been pushed out of the picture by a mandatory seven-speed automatic transmission.
As it has in the past, Infiniti touts its all-new Q50 as a luxury sport sedan worthy of the title. Decades ago, impressive performance statistics may have sealed the deal. Yet there is much more to the assignment today, as the model must offer premium appointments, sophistication and engaging driving dynamics if it's going to entice and capture the next-generation of young, premium buyers - much like the G35 did for me ten years ago.

Infiniti Q50S getting G37's hydraulic steering for 2016

Sometimes, new technology doesn't make things better. Take the march of power steering technology as an example. Electrically assisted systems are in vogue at the moment for their ability to increase fuel efficiency, but tuning them to offer good feedback remains something of a dark art. Some automakers get it, but most don't. The previous hydraulically assisted setups just seem to be inherently more communicative when driven with enthusiasm. And it looks like Infiniti might be learning this lesson the hard way.
In talking with Keith St. Clair, the luxury brand's head of product planning, Car and Driver has learned that the Q50S is probably going to ditch its standard electrically assisted steering in favor of a hydraulic system derived from the old G37, a model soon to be renamed the Q40. The system should make the sedan more engaging behind the wheel, but it still won't help those who tick the option box for Infiniti's controversial Direct Adaptive Steering drive-by-wire system.
According to St. Clair, Infiniti's engineers have heard the complaints of critics and previous G37 owners about the Q50S model's electric steering system, and wanted to see what they could do. They didn't have to go far to figure it out - all it required was taking the steering rack off of a G37 and putting it onto the Q50S. After a little tweaking, "the car is a blast to drive," St. Clair reports. Now, the company is said to be fast-tracking the switch, and it could be ready for the 2016 model year.

Watch Sebastian Vettel become first driver to lap Sochi GP circuit

In April of last year, Sebastian Vettel and David Coulthard drove the unpaved Sochi Formula One circuit in a pair of Infiniti M sedans, getting both muddy and airborne in the process. Now with tarmac laid down and fences put up, Vettel and Coulthard have gone back to the Black Sea vacation spot for another hot lap, this time in a Q50 Hybrid and without the need for mud flaps.
Sochi has earned the blessing of F1's race director, so now the next test will be the fans. With a healthy amount of wall-and-fencing along the straights, it has shades of Valencia for the viewer. We hope it will be much more exciting than its Spanish counterpart when racing happens on October 12. You'll find more videos below covering Infiniti's visits to the Sochi Autodrom, and a press release on the latest lap.
