Hello folks,

So MotorTrend did a nice tidbit here comparing the Q50's performance numbers against previous tests of the G35/37 to see how it stacks up.


It may have a new name, but the 2014 Infiniti Q50 ain’t nothing but a G thang (sorry, I had to). The 2014 Infiniti Q50S we just took to the track for its First Test has big shoes to fill, following the much-loved Infiniti G37 and the original Infiniti G35. (Yes, there was an Infiniti G20 with a 10.7-second 0-60 mph time in 1999, but that front-drive, four-cylinder sedan shares nothing in common with the more recent cars). So how does the new Q50 stack up to its predecessors? Let’s take a look at the numbers and find out.

At first glance the 2014 Q50 doesn’t deviate much from the formula that made the G37 and G35 so successful. The car is still a rear-drive-based sports sedan with edgy styling and a V-6 powertrain. In fact, the Q50′s powerplant carries over unchanged from the G before it, with its 3.7-liter V-6 cranking out 328 hp and 269 lb-ft of torque. Under the skin, some of the 2014 Q50′s mechanical bits change drastically from its predecessors, with its drive-by-wire steering the most noteworthy. The 2014 Q50S puts down some impressive preliminary specs:

2014 Infiniti Q50S: 3.7-liter V-6/328-hp/269-lb-ft; 7A/RWD
0-60 mph: 5.2 seconds
Quarter-Mile: 13.8 sec @ 102.1 mph
60-0 mph: 110 feet
Skidpad: 0.87 g (avg)
Figure Eight: 26.3 sec @ 0.71 g (avg)

The Q50 may be the newest and most efficient, but it’s hardly the quickest G we’ve ever tested. That honor belongs to the last-generation rear-drive 2009 Infiniti G37 S, which had the same engine and a seven-speed automatic.

2009 Infiniti G37 S: 3.7-liter V-6/328-hp/269-lb-ft; 7A/RWD
0-60 mph: 5.0 sec
Quarter-Mile: 13.5 sec @ 105.3 mph
60-0 mph: 110 ft
Skidpad: 0.90 g (avg)
Figure Eight: 26.4 sec @ 0.68 g (avg)

The all-wheel-drive version, the 2009 G37x S, isn’t far off the mark, either:
2009 Infiniti G37x S: 3.7-liter V-6/328-hp/269-lb-ft; 7A/AWD
0-60 mph: 5.4 sec
Quarter-Mile: 13.9 sec @ 100.5 mph
60-0 mph: 120 ft
Skidpad: 0.85 g (avg)
Figure Eight: 26.8 sec @ 0.66 g (avg)

Even when the last-generation Infiniti G was just the G35, with the previous-generation of Nissan’s VQ V-6, the sport sedan still posted up numbers within spitting distance of the new Q50. Just take a look at our old long-term 2007 G35 Sport, which only had 306 hp to work with.

2007 Infiniti G35 Sport: 3.5-liter V-6/306-hp/268-lb-ft; 5A/RWD
0-60 mph: 5.3 sec
Quarter-Mile: 13.9 sec @ 99.9 mph
60-0 mph: 108 ft
Skidpad: 0.91 g (avg)
Figure Eight: 25.9 sec @ 0.69 g (avg)

The first-generation Infiniti G35, which won our Car of the Year award in 2003, also put up impressive performance figures – despite the fact that it had 280 hp and didn’t benefit from the leaps in tire technology since then. In 2005 we tested a G35 with a five-speed automatic, and in 2003 a G35 with a six-speed manual. Here’s how they performed:

2005 Infiniti G35: 3.5-liter V-6/280-hp/270-lb-ft; 5A/RWD
0-60 mph: 6.5 sec
Quarter-Mile: 14.7 sec @ 95.9 mph
60-0 mph: 112 ft
Skidpad: 0.88 g (avg)
Figure Eight: 26.6 sec @ 0.66 g (avg)

And the manual car:
2003 Infiniti G35: 3.5-liter V-6/280-hp/270-lb-ft; 6M/RWD
0-60 mph: 5.8 sec
Quarter-Mile: 14.3 sec @ 100.3 mph
60-0 mph: 110 ft
Skidpad: 0.84 g (avg)

My favorite (driving wise) is the 2007-2008 G35S. The 5 speed auto was much more responsive than the current 7 speed, it was lighter than the G37 and the
VQ35HR is smoother than the 3.7.
I like the rawness of my 2004 sedan. It's hard to replicate, seems like they softened it up a lot over the years. The Q50 feels tighter though and more "grown up", with a more compliant suspension and better chassis control.

I think the 5 speed transmission had a lot to do with the urgency of the older cars, with shorter gearing overall but I will never miss the 1-2 upshift jerk in the winter. The 7 speed has been roundly criticized and Infiniti finally got it right in the Q50 from what I've experienced and reviews have said.
