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.

A beautiful conundrum | 2017 Infiniti Q60 First Drive

"OK, this should be fun." Hands are rubbed together excitedly. It's a rear-wheel-drive sport coupe painted candy apple red. It's sleek, slinky, and uniquely styled. It's from the same folks who, in the 2000s, finally showed that BMW could be matched in the whole sport sedan/coupe game. Oh, and it has 400 horsepower. Four-hundred! With a four. And yet the 2017 Infiniti Q60 underwhelms. What looks so good on paper instead is rather conflicted, stuck somewhere in no-man's land between the traditional expectations of a performance sport coupe and those of comfier, more luxurious cruisers that isolate and pamper their occupants. It's a serious effort with serious engineering and a clear desire to be innovative, but at least in the range-topping Red Sport model we tested, it fails to come together in a way that truly excites or indulges. A great coupe should do one or the other, and ideally both. To explain, let's start under the hood, where Infiniti's all-new "VR" series 3.0-liter twin-turbo V6 makes its second appearance after debuting in the Q60's four-door sibling, the Q50. In the Q60 Silver Sport model, it produces 300 horsepower and 295 pound-feet of torque courtesy a pair of turbochargers that create 8.7 psi of boost. In the Red Sport, the knob is turned up to 14.7 psi, resulting in the oh-so-salivatory magic number of 400 hp along with 350 lb-ft of torque. A device known as an optical turbo speed sensor, special to the Red Sport, manages and maintains that extra boost, while an electric motor fitted to the valve timing system serves to quell any loss in throttle response due to forced induction. The Red also gets a second water-cooled intercooler, which, in both models, is distinctive for its more compact size, shorter airflow path, and, according to Infiniti, a resulting reduction in turbo lag and more immediate engine response. It's certainly a clear improvement on the somewhat rough 3.7-liter "VQ" V6 it replaces, which increasingly felt and sounded a little out of place in a luxury car. The new VR30DDTT, as it's so eloquently named, is buttery smooth and indeed responsive, likely capable of convincing luxury-car owners used to naturally aspirated V6s that everything's business as usual. Honestly, its character is reminiscent of a silky Honda V6. In some respects, that's a great thing. In others, it's where the Q60 starts to fall flat.

Infiniti Prototype 9 is a wonderfully beautiful EV grand prix car

Few automobiles are as elegantly beautiful as the open-wheel grand prix cars of the 1940s, '50s and '60s. The simple, slender shapes of these cars bear no extravagant flourishes or adornments. The purposeful design is what gave these cars their beauty, and it's these classic machines that inspired the new Infiniti Prototype 9. Teased earlier this week, this concept blends old and new, with classic lines hiding a modern all-electric powertrain. The Prototype 9 will make its full debut next week at the 2017 Pebble Beach Concours d'Elegance. Infiniti says the car was built around a simple idea: what would a 1940s Infiniti grand prix car look like? While the silver paint may be more German than Japanese, the design could easily be mistaken for an actual '40s grand prix car. Only the Infiniti-styled grille gives it away. Everything about it, from the thin bias-ply tires wrapped over center-locking wire wheels to the bulging screws around the driver's seat, is pitch perfect. Underneath that achingly long hood rests a prototype electric motor and battery from Nissan's Advanced Powertrain Department. The combo sends 148 horsepower and 236 pound-feet of torque straight to the rear wheels. That's good enough to send the svelte 1,962 lb car to 62 mph in just 5.5 seconds. Top speed is right at 106 mph. While speed may die off towards the top end, all that torque and a 43/57 front to rear weight distribution should make the Prototype 9 a riot on a small, tight circuit. There's only enough juice in the battery for about 20 minutes of flat-out racing. The handmade steel body rests on a steel ladder-frame chassis. The front suspension uses a leading-arm rigid axle with transverse leaf spring while the rear uses a De Dion axle, also with a transverse leaf spring. The Prototype 9 also uses old-school hydraulic rotary type dampers. There's no power steering and no brake booster for the four-wheel disc brakes. The car was designed and built by a number of different departments within Infiniti and Nissan. A simple sketch expanded as more and more designers and engineers wanted to have a hand in the project. The steel body panels were all shaped and hammered by hand. The bare cockpit is only adorned with a thin seat, three gauges, a few switches, a gear selector and the steering wheel. The gauges are set into a fixed aluminum hub in the center of the steering wheel.
