Infiniti Q50 offers auto first: steer-by-wire

Q&AWhy the name change?The Q50 replaces the G sedan. Infiniti now uses the letter Q plus a two-digit number for cars and QX plus a two-digit number for SUVs. That means the G coupe and cabrio became the Q60 and the EX SUV is now the QX50.How does the steer-by-wire work and what does it cost? There is no more mechanical connection between the steering wheel and the wheels. Steering happens via electronically controlled motors. The option costs 1,000 euros.Does steer-by-wire provide a noticeable difference?Driving is more precise because the steering adjusts based on speed and road type. It is more comfortable than conventional systems because the wheels no longer transmit road defects to the driver's arms via the steering wheel.How does the Q50 compare with the German premium brand?Size-wise, the Q50 is like the Audi A6/BMW 5 series, but its powertrains are closer to the Audi A4/BMW 3 series.How does the gasoline-electric hybrid compare with the diesel?The hybrid offers more than twice as much power, 364hp vs. 170hp, while CO2 emissions are only 26 percent higher at 144g/km (6.2 liters per 100km) vs. 114g/km (4.4l/100km).Is the gasoline engine only available as a hybrid? Yes. There is a choice of either rear-wheel drive or all-wheel drive. With the Q50, Infiniti is counting on a world-first technology for a serial production car – steer-by-wire – and the addition of its first diesel powertrain to lure European premium-car buyers from the dominant German brands.
