Final Recap: Days 2 and 3 notes, quotes, and takeaways from the US Grand Prix

The Texas grass no longer rustles with 2.4-liter V8 exhaust blown at 18,000 revs, the Texas dust is no longer raised by hard-compound Pirellis. We saw a lot and learned a lot while we were there as guests of Infiniti, and after our Day 1 and race recaps, here are the bits left over from our time spent with the carmaker and Red Bull Racing, including thoughts on a "wicked" race, Christian Horner's quest for a more level playing field, Infiniti "going longer and deeper," and why Mario Andretti should get a police escort at the beginning of a race but not a microphone at the end...

A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

Infiniti prices renamed 2014 QX50 and QX80 crossovers

Earlier this week, Infiniti revealed the pricing for its two midsize crossovers, but now it has announced the pricing for its renamed bookend utility vehicles, the compact QX50 crossover and the fullsize QX80 SUV. Those looking for a smaller luxury crossover will be glad to learn that the 2014 QX50 now starts at $34,400* (a price drop of $2,500 compared to the 2013 EX), while pricing for the 2014 QX80 will remain the same as the 2013 QX56, starting at $61,350* (*prices do not include $995 for destination).
In terms of packaging, the QX50 will carry over unchanged, but the QX80 gets a new Backup Collision Intervention system as a part of its optional Technology Package. All of Infiniti's 2014 QX utility vehicles are on sale now, but for more details about the QX50 and QX80, scroll down for the official press release.
