McLaren working on P15 supercar to slot between 650S and P1

McLaren has been busy these past few years. It launched the MP4-12C in 2011, the 12C Spider in 2012, the P1 in 2013 and (most recently) the 650S in 2014. But it's not about to stop there. It's got an "entry-level" model in the works, set to take on the Porsche 911, and - according to information reported by Car and Driver and confirmed by McLaren in correspondence with Autoblog - a new flagship model, too.
The project is internally codenamed P15, and it calls for a new flagship that will cap the company's lineup once the P1 finishes its limited production run, but carry a price tag in the neighborhood of $500k to slot in between the P1 and the new 650S.
Just how, you wonder, can McLaren possibly develop another supercar each year? Simple: underneath, they're all essentially the same. (Only we're sure it's anything but simple.) That is to say they're all based on the same carbon monocoque structure and powered by the same 3.8-liter twin-turbo V8 mated to a seven-speed dual-clutch transmission driving the rear wheels. What differentiates them is what the engineers in Woking build around that monocoque and how they tune the engine: +/- 600 horsepower in the 12C (depending on the year it was built), 640 hp in the 650S, or 727 hp in the P1 (with another 177 from the electric assist). The 911 fighter would likely develop in the 500hp range, and the P15 will probably land in the upper 600 (or lower 700) range.

Honda revamps F1 engine for McLaren

Things haven't been going smoothly for Honda since returning to Formula One, and the Japanese automaker says the challenge has been greater than it anticipated. But after a stronger showing at the recent Hungarian Grand Prix, Honda says its reliability issues are behind it and is working on introducing a revamped engine for the second half of the season. "I am confident our reliability problems are now behind us, which means we can turn our attention to increasing power," Honda racing chief Yasuhisa Arai told Autosport. "After the summer shutdown our plan is to apply a new-spec engine using some of our remaining seven tokens." The "tokens" to which Arai refers are a way for the FIA to limit engine development. The power units are broken down into 66 such tokens in the regulations, and each engine supplier can change up to 32 of them throughout the season. The allowance was at first afforded only to returning suppliers Mercedes, Ferrari, and Renault, but Honda succeeded in convincing the FIA to allow it the same leeway. Honda has been spending its development tokens on fixing reliability issues, but will shift its focus to improving performance. The McLaren team that Honda powers has only gotten both of its cars to the finish line at two out of 10 races this season. Most of those problems came down to the new engine package. That's compared to only two retirements the team suffered last season, when it was still under Mercedes power, and none the year before. In Hungary, however, the team not only got both cars to the finish line, but placed both in the points for the first time this season. "The sport has changed immensely since the McLaren-Honda 'glory days'," said Arai. "The current technology is much more sophisticated, and it is tough to make a good racing car. We knew it wouldn't be easy, but perhaps we didn't imagine it would be this hard." The Japanese manufacturer is now spending the summer break developing its power unit. Many of those changes are expected to be rolled out in time for the Belgian Grand Prix later this month, with the rest to follow in the ensuing races. Beyond reliability, engine performance is particularly important for the high-speed races at Spa and Monza, where the subsequent Italian Grand Prix will be held early next month. Related Video:

Carmakers, NHTSA to unveil auto-emergency braking agreement tomorrow

Happy St. Patrick's Day Eve. Tomorrow, there will be green beer, corned beef and cabbage, and automatic emergency braking for all. Weird combo, we know. But on St. Patty's we can expect an official announcement from a pact of automakers making auto-braking systems standard equipment by 2022. That's per a report from Reuters, which cites three sources familiar with the plans. Originally announced in September 2015 by 10 automakers and the National Highway Traffic Safety Administration, the agreement is expected to be even larger when the details are unveiled tomorrow. According to Reuters, the manufacturers of 99 percent of the US domestic market's vehicles will be represented by the new agreement. It's believed that standard AEB systems could prevent thousands of accidents across the country. Expect more on the official announcement when it's made. Related Video:
