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...

Formula 1 seeking independent engine supplier

Formula 1 could get a new engine supplier in the near future, if Bernie Ecclestone and the independent teams gets their way. According to Autosport, the FIA is soon to open the contract up for bids, and there are already several manufacturers that have expressed interest. Currently Mercedes, Ferrari, Renault, and Honda supply engines – both to their own premier teams (Red Bull and McLaren for the latter two) but also to other teams like Williams, Sauber, and Toro Rosso. Because the new turbocharged V6 hybrid power units cost those four suppliers so much to develop, they're charging their customer teams big bucks – around $20-30 million per season – to provide the engines. These costs are much higher than the $10 million or so it used to cost to purchase a V8 engine under the previous regulations. Ecclestone figures it's time to bring in another supplier who will not run their own team and not play favorites, but will supply engines to private teams at a lower cost. There are already a number of potential suppliers under consideration. One of them is said to be Cosworth, which has a long history in the series stretching back to 1963. The British firm stepped back between 2007 and 2009, returned in 2010, and dropped out again after 2013. The development could be of particular benefit to Red Bull, which has been unable to find an engine supplier and could be forced out of the series as a result. The team has long been powered by Renault, but that relationship has grown sour. And the other three engine manufacturers have not been forthcoming in offering an alternative arrangement for the team.

Infiniti Q60 Concept paints a pretty picture of the brand's future

Infiniti's final teaser for the Q60 Concept may have given away the shape of the curvy coupe ahead of its debut at the 2015 Detroit Auto Show, but that's not necessarily such a tragedy for this model because the design has so many subtle touches. The more you look at it, the more cool details and ornate lines you notice. What initially looks fairly simple up front belies a multitude of fascinating details, including the F1-inspired lower air dam and the subtle fin at the tip of the hood. The design around the C-pillar may be complicated but is also attractive thanks to the confluence of design from the rear fender arch, beltline and crescent-shaped cutout in the window. The concept's interior also takes a minimalist approach. It's predominantly covered in cream leather and features sports seats in quilted leather. A mix of Alcantara and carbon fiber trim are able to show off the concept's performance intentions, though. Meanwhile the glass roof makes sitting behind the wheel feel airy and inviting. Underneath, the Q60 Concept's arching hood is the company's conceptual 3.0-liter, twin-turbocharged V6 and a seven-speed automatic. Infiniti promises the production of the mill is coming in the next two years. The big question is whether the mix of sharp edges and flowing lines on the Q60 Concept really see production without too much alternation. Infiniti plans to unveil the production version next year. Until then, check out how the model appears now on the floor of the Detroit show.
