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:

Toyota Camry to go turbo

As automakers strive to meet regulations, turbocharging is rapidly becoming the norm whether looking at pickups, sports cars or family sedans. However, Toyota remains a stalwart to the changing tide, and for the time being a trip into one of the brand's dealers shows nary a hint of forced induction – probably not for long, though. With models like the Lexus NX 200t and forthcoming IS 200t pointing the way, a big shift is afoot for one of the Japanese automaker's most popular products. Obviously, Toyota is no stranger to forced induction for performance applications like the turbocharged models of the Supra and MR2 in the '90s. But rather than reducing lap times, the latest application is more about improving emissions and fuel economy. According to Automotive News, the Camry is getting a 2.0-liter turbo four-cylinder in the near future as a replacement for its V6 engine option. The 3.5-liter six currently in the venerable sedan already makes 268 horsepower and 248 pound-feet of torque, versus 235 hp and 258 lb-ft in the NX 200t or 241 hp and 258 lb-ft in the IS from the new four. The base four-cylinder also might receive some upgrades. It could grow larger and run on the Atkinson cycle to find improvements, according to Automotive News. There might be a move towards CVTs, as well. Toyota is hardly alone in the shift towards forced induction. Honda is known to have a 1.5-liter turbo mill on the way for the next-gen Civic. In addition, that engine might find its way into the Accord and CR-V as well, according to Automotive News. Among the major Japanese automakers, only Nissan is taking a more measured approach towards forced induction in mainstream models. Rather than going all-in on turbos, the company is expected to shift more of its engines to direct injection to go after fuel economy gains.

McLaren F1 team sets deadline for engine decision amid Renault speculation

BUDAPEST - McLaren says the next five weeks will be the key to deciding which engine it will use next season, with speculation mounting that the former world champions could ditch Honda and switch to Renault. Chief operating officer Jonathan Neale told Reuters at the Hungarian Grand Prix that "everybody is talking to everybody," but time was running out. "We've got to land those decisions in the next four or five weeks," he said, speaking from a design perspective and because drivers like McLaren's Fernando Alonso were waiting to see what engines teams had before committing to new deals. "I think there is a solution out there for everybody and I hope it's one that will be able to retain Fernando in this team." McLaren scored their first double-points finish of the season in Budapest on Sunday with double world champion Alonso finishing sixth, a day after his 36th birthday, and Belgian Stoffel Vandoorne 10th. The nine points lifted McLaren off the bottom of the standings just before the August break and factory shutdown, a result that Neale compared to scoring a goal before halftime. Alonso's future is a key concern, with the Spaniard out of contract and saying McLaren needs to provide a competitive car to keep him. Honda's power unit has been beset with problems since the partnership started in 2015, the engine neither reliable nor competitive. Hungary, the slowest permanent circuit on the calendar, reduced those shortcomings, but the next two races in Belgium and Italy are two of the fastest, where engine horsepower is of critical importance. McLaren is Honda's sole team in Formula One. A proposed partnership with Sauber terminated last week with the Swiss team choosing to stay with Ferrari. A split from McLaren could force the Japanese manufacturer out of the sport, but Neale hinted at an alternative. "You'll have seen the media speculation that there's discussions with Toro Rosso," he said. Toro Rosso use Renault engines, but a switch to Honda — which could bring welcome funding to a team whose Red Bull parent has considered a sale in the past — would free the French units for McLaren. The Renault engine has won a race this season with Red Bull and could satisfy Alonso, who won both his titles with the French manufacturer. The other alternatives to Honda are Mercedes and Ferrari, but Neale recognized that putting a Ferrari engine in a McLaren, the Italian team's historic arch-rivals, was highly unlikely.
