If we were to talk in detail about all the technical solutions crammed into the Infiniti FX 50S we drove we would probably need a couple of chapters more. Let's just say that as far as the juicy technical bits go, this is one fine automobile.
The 5.0-liter V8 is pretty old-school when it comes to ways of achieving its class-leading (for this type of engine) power and torque figures. No less than 390 horsepower and 500 Nm (368.8 lb ft) of torque are achieved by natural-aspiration, ready to make you feel like you're driving something much smaller and lighter, instead of a 5,000 pound behemoth.
Apart from a somewhat large displacement and intelligently-variable valve, admission and exhaust control, there aren't that many technical solutions to make you think this engine is so efficient when it comes to delivering so much performance, but it is.
Partly "to blame" for the sub-six second sprint from naught to 100 km/h (62mph) is the old-school seven-speed automatic transmission. Although it's not a double-clutch sequential one, using a torque converter instead, it managed to impress us by both its smooth operation and the times required to shift, which is faster than the blink of an eye.
Another impressive piece of technology, standard on the "S" trim level we tested, is probably the Active Steering system, which can vary the steering ration between 12.0:1 and 18.5:1, depending on the speed of the car. This can either facilitate parking at low speeds and handling/comfort at higher speeds, just like the eponym system from BMW. To be entirely truthful, we kind of found the steering to be harder than you'd expect at all speeds, but that's a good thing if you're the "sportier type" of driver.
Apart from the electronically-controlled dampers, which we already covered in our "Feed Me Lies" chapter, we should probably also talk about the "creme de la creme" as far as technical solutions go on this trim level – the all-wheel steering system. Working similarly to the ones we now see on certain high-end BMW models, this system can induce up to one degree of steer to the rear wheels. What many people don't know is that a similar, but more rudimentary system was used by both companies in the late 1980s and early 1990s.Continue reading
