2013 Infiniti EX, FX Get 3.7-liter V6

Here's a change that's about four years in the making: The Infiniti EX and FX will upgrade to the corporate 3.7-liter V6 for the 2013 model year, becoming the 2013 EX37 and 2013 FX37.

The change shouldn't affect performance much, especially in the FX, which already had a version of the 3.5-liter V6 rated at 303 hp and 262 lb-ft of torque. (The EX35's V6 was listed at 297 hp and 253 lb-ft).

The 3.7-liter engine will carry a 325-hp rating; Infiniti hasn't released a peak torque figure yet, but it's likely to be in the high 260s, low 270s if the G37/M37 are any indication.

Both crossovers already had the company's seven-speed automatic transmission, so there won't be any changes there, save for possible (minor) adjustments to the gearing.

The FX37 goes on sale in July. The EX35 will show up in August.

Other changes for 2013 include the addition of Infiniti's Moving Object Detection (MOD) system for the FX37/FX50 -- a feature you've no doubt become acquainted with in commercial for the new JX35. It's included if you order the Around View Monitor parking camera.
