Renault looks to long-term engine boost
Renault is developing revolutionary engine technology which could feature in its new breed of Formula 1 powerplants as early as 2001
According to Autosport's sister publication Autocar, Renault is pressing ahead with research into a radical new valvegear system. It utilises small, electro-magnetic solenoids to operate the valves and could set a new trend in the design of engine internals.
In 1986, Renault pioneered the use of pneumatic valve actuation that increased the revving potential of the engine. Experts believe that solenoid technology could push F1 rev bands beyond the 20,000rpm mark.
The system is current being developed by Renault's engine department primarily for road car uses, as it would offer increased driveability, lower emissions and better fuel consumption. Mercedes is also believed to be investigating a similar system.
A leading F1 engine specialist said: "The downside for racing applications is that solenoid technology currently still carries with it a weight penalty. The upside is the saving in frictional losses it offers."
In the meantime, Renault will also innovate by using the widest angle V10 engine in the F1 field next year. Its 111-degree unit will debut in the hands of new test driver Mark Webber at Silverstone on Friday in the back of its Benetton B200B muletta chassis.

How a bad car creates the ultimate engineering challenge
While creating a car that is woefully off the pace is a nightmare scenario for any team, it inadvertently generates the test any engineering department would relish: to turn it into a winner. As Mercedes takes on that challenge in Formula 1 this season, McLaren’s former head of vehicle engineering reveals how the team pulled of the feat in 2009 with Lewis Hamilton
The under-fire F1 driver fighting for his future
Personable, articulate and devoid of the usual racing driver airs and graces, Nicholas Latifi is the last Formula 1 driver you’d expect to receive death threats, but such was the toxic legacy of his part in last year’s explosive season finale. And now, as ALEX KALINAUCKAS explains, he faces a battle to keep his place on the F1 grid…
The strange tyre travails faced by F1’s past heroes
Modern grand prix drivers like to think the tyres they work with are unusually difficult and temperamental. But, says MAURICE HAMILTON, their predecessors faced many of the same challenges – and some even stranger…
The returning fan car revolution that could suit F1
Gordon Murray's Brabham BT46B 'fan car' was Formula 1 engineering at perhaps its most outlandish. Now fan technology has been successfully utilised on the McMurtry Speirling at the Goodwood Festival of Speed, could it be adopted by grand prix racing once again?
Hamilton's first experience of turning silver into gold
The seven-time Formula 1 world champion has been lumbered with a duff car before the 2022 Mercedes. Back in 2009, McLaren’s alchemists transformed the disastrous MP4-24 into a winning car with Lewis Hamilton at the wheel. And now it’s happening again at his current team, but can the rate of progress be matched this year?
Why few could blame Leclerc for following the example of Hamilton’s exit bombshell
OPINION: Ferrari's numerous strategy blunders, as well as some of his own mistakes, have cost Charles Leclerc dearly in the 2022 Formula 1 title battle in the first half of the season. Though he is locked into a deal with Ferrari, few could blame Leclerc if he ultimately wanted to look elsewhere - just as Lewis Hamilton did with McLaren 10 years prior
The other McLaren exile hoping to follow Perez's path to a top F1 seat
After being ditched by McLaren earlier in his F1 career Sergio Perez fought his way back into a seat with a leading team. BEN EDWARDS thinks the same could be happening to another member of the current grid
How studying Schumacher helped make Coulthard a McLaren F1 mainstay
Winner of 13 grands prix including Monaco and survivor of a life-changing plane crash, David Coulthard could be forgiven for having eased into a quiet retirement – but, as MARK GALLAGHER explains, in fact he’s busier than ever, running an award-winning media company and championing diversity in motor racing. Not bad for someone who, by his own admission, wasn’t quite the fastest driver of his generation…
