How This 2.0-litre V4-engined Car Was Quicker Than F1

Event / Context

The video visits Silverstone for a Porsche 75 years in the UK “Sunsteed” event, featuring rare museum race hardware brought back to life. The centerpiece is a running Porsche 919 LMP1, nearly a decade after retirement.

Featured Car: Porsche 919 LMP1 (2017)

• The car is described as an “ultimate” 919 from the final year of the LMP1 program.
• Porsche is said to have retired the LMP1 program after 2017 (with Audi) and shifted focus toward Formula E.

Engine / Powertrain Design (Technical Focus)

2.0L V4 Layout (Unusual Choice)

• The 919 uses a 2.0L V4, which is notably uncommon in cars (more typical of performance motorbikes).
• Despite the small displacement and cylinder count, subtitles claim it produces about ~500 hp in race trim.

Hybrid + Turbo System

• A massive turbocharger powers the combustion side.
• A hybrid generator supports the hybrid system (charging during braking/acceleration).
• Hybrid power drives the front axle, enabling all-wheel drive during full deployment.

Performance Claims (Subtitles)

• Top speed: ~211 mph
• 0–60 mph: ~2.2 seconds (claimed)

Why Porsche Chose a V4

The video frames the V4 decision as both a regulation and engineering outcome:

• LMP1 rules at the time were influenced by fuel flow rate, leaving manufacturers more freedom otherwise.
• Porsche is described as choosing a large hybrid system, allowing it to use a smaller engine.
• Subtitles claim Porsche evaluated various engine concepts, but calculations led to a 4-cylinder turbo being the most competitive while meeting fuel-flow targets.

Packaging / Structural Advantage

• The V4 is argued to be superior to an inline-4 because it can be built as a stressed member that bolts into the carbon tub, supporting drivetrain/suspension attachment.
• The subtitles claim an inline-4 didn’t offer enough torsional rigidity.

The video humorously emphasizes the V4 as “stumpy,” highlighting its compact crank geometry and rigidity benefits.

Early Reliability / Driveability Problems

A major analysis point is that the V4’s inherent imbalance caused problematic vibrations early in the 919 program:

• Components reportedly snapped/shook loose.
• Vibration frequency was said to interfere with drivers during testing—impacting their ability to breathe, speak, or see.

The Fix (Not Trivial)

• The described solution was changing the engine firing order.
• Subtitles stress that this required more than a simple adjustment:
  • new crankshaft
  • new cam timing
• This allegedly delayed testing and contributed to early struggles in 2014.

Later Success

Despite early issues, the video says the 919 later became dominant in endurance racing.

Peak Output and “Evo” Context (How It Beat F1, Per Subtitles)

• The 919 Hybrid is stated (subtitles) to win 24 Hours of Le Mans in 2015, 2016, 2017.
• It is explained that LMP1 restrictions constrained the car’s configuration.
• When restrictions were removed (“taking away fuel flow restrictions”), subtitles claim output rose to about ~720 hp.

“919 Evo”

With freer aero rules and more hybrid deployment, it became the 919 Evo, described as quicker than F1.

Spa Lap Time Comparisons (Subtitles’ Claims)

• Standard 919: ~1:54.7
• Lewis Hamilton (Mercedes F1, same year): ~1:42.5
• 919 Evo: ~1:41.7, nearly a second faster than the F1 time quoted, and far quicker than standard 919

How They Get It Running Now (Museum Practicalities)

Museum caretaker Armen explains the approach for long-stored hardware:

• For this museum-ready car, they remove the high-voltage battery.
• It still runs using a 12V engine battery (implied as the basis for non-hybrid running).
• The video clarifies that it’s treated like a pure internal combustion setup for museum operation.
• Regarding an engine rebuild interval, the answer is essentially “never”—the subtitles imply they install a spare engine if needed.
• Power for the running configuration is estimated at about ~580–600 hp, since track-style limits (e.g., fuel limiters) are not applied.

Other Porsche “Engine Lineage” Digressions

The video also covers other Porsche race prototypes at the event, connecting them to engineering stories:

• Porsche 917 (flat-12, early chassis)
• Porsche RS Spider
  • LMP2-derived, but said to beat LMP1 cars at times due to downforce/power balance

RS Spider → 918 → 919 Genealogy (Subtitles’ Explanation)

The video claims the RS Spider 3.4L flat-plane crank V8 spawned:

1. the 4.6L V8 used in the 918
2. experimental steps toward a 4-cylinder 1.7L racing concept for the 919 (via dyno work and cylinder-head-side removal)
3. later influence on Porsche 963 (LMDH) using the 3.4L base with two turbochargers

It also notes bodywork evolution and the class advantage of lighter LMP2 with lots of downforce, enabling it to take on LMP1 in certain circuits (e.g., US events).

Nürburgring Lap Record + Driver Perspective

Driver Timo Bernhard is interviewed:

• He recalls early development drives and initial vibration issues.
• He describes the Nürburgring feel:
  • extreme cornering speed
  • strong acceleration
  • a tight, racing-focused driving sensation
  • the role of DRS / energy deployment
• He mentions driving moments such as cresting fast sections and deploying energy uphill.
• He also comments on the program’s ending—shifting from a difficult start to multiple championships, followed by an abrupt conclusion—and how the team morale evolved.

Jump Starter Sponsor (Included in Subtitles)

A sponsor Ring of Automotive promotes a 2000A Ultra Boost jump starter, claiming support for gasoline/diesel engines and use on large engines (mentioned alongside specific cars).

Main Speakers / Sources (Stated or Implied)

• Armen (Porsche Museum staff member who keeps/starts the 919 for display/running)
• RS Spider driver (name unclear in subtitles), discussing RS Spider performance vs LMP1 and experiences, plus additional mention of Porsche LMDH/LMP content (including V10-related material)
