Hamilton on New F1 Rules
Lewis Hamilton has described the new Formula 1 regulations introduced this year as "ridiculously complex," emphasizing that "none of the fans are going to understand it." The seven-time world champion was specifically addressing the heightened complexity of energy management required by the updated power units, which now feature an almost equal split of power between the internal combustion engine and electrical components.
Speaking after driving the Ferrari during the first morning of the pre-season test in Bahrain, Hamilton remarked on the technical briefings he attended:
"I sat in a meeting the other day and they're taking us through it. And yeah, it's like you need a degree to fully understand it all."
The new regulations have created a scenario where engines operate under energy constraints for much of the race, compelling teams and drivers to optimize energy recovery strategies. This has resulted in unconventional technical approaches and driving methods.
Energy Management and Driving Techniques
Among the novel techniques necessitated by the rules are avoiding full throttle when exiting corners before initiating a qualifying lap, as well as reducing speed on straights to conserve energy. These strategies represent a significant shift from traditional racing tactics.
Energy Recovery Methods
There are four primary types of energy recovery under the new rules:
- Regenerative braking: Energy is recovered by the motor during braking before corners.
- Part-throttle overload: The battery draws power from the engine on sections of the track where full throttle is unnecessary, such as during cornering when the engine may run at high revolutions without full power application.
- Lift and coast: Drivers lift off the throttle before corners, allowing the electric motor to operate against the engine, aiding energy recovery.
- Superclip: The electronic control unit redirects energy to the battery even when the driver maintains full throttle on straights.
These recovery methods are further complicated by the presence of a 'boost' button that drivers can activate to gain extra power for overtaking. However, using this boost risks depleting energy reserves, potentially leaving the driver vulnerable to being overtaken on subsequent straights.
Hamilton explained, "If you look at Barcelona, for example, we're doing 600 metres lift and coast on a qualifying lap. That's not what racing is about. Here (in Bahrain), we're not having to do that because there's lots of braking zones."
Additionally, drivers are required to use lower gears than preferred to enhance energy recovery. Hamilton elaborated:
"The low gears that we have to go down into is just because we can't recover enough battery power. We can't recover enough battery power, so that's why we have to go and rev the engines very, very, very high. So we're going down to second and first in some places just to try to recover that extra bit of power."
Context and Future Outlook
Hamilton's observations come at a stage when teams are still familiarizing themselves with their new cars, and the full competitive impact of the regulations will only be apparent once the season begins. It is also important to note that some energy management strategies, such as lift and coast, were already in use with last year's power units.
Regulatory authorities are expected to allow the new rules to stabilize before considering any modifications or reacting hastily.
