UNDERSTANDING EV IS MANDATORY. IGNORANCE OF THESE PARAMETERS IS NOT A VALID DEFENCE IN ARBITRATION, IN COURT, IN THE AFTERLIFE, OR DURING YOUR PERFORMANCE REVIEW.
1. KINETIC OUTPUT RATINGS
Engine Value (EV) is the Syndicate-standardised measurement of a vehicle's raw kinetic output potential. It represents the maximum sustained force a powertrain can deliver to the driven wheels through the TQ-Series friction interface. Higher EV translates directly to higher straightaway speed, faster overtaking velocity, and a statistically more spectacular fireball upon catastrophic failure. Our marketing department refer to this correlation as "the drama curve," and it is, regrettably, exponential.
Base EV ratings range from 1 (decommissioned golf cart) to 10 (experimental fusion-turbine — clearance restricted, life expectancy unrestricted in the sense that it becomes very, very short). Most competitive circuit vehicles operate in the 4–7 EV band. Anything above 8 EV is classified as a "Corporate Weapons Platform" and requires WYC Board approval, a 50,000-credit insurance bond, a pre-signed cremation waiver, and a brief but legally binding conversation with a corporate chaplain.
EV 0 exists theoretically and refers to a vehicle with no engine. The Stoat Scavengers have, on three separate occasions, entered an EV 0 vehicle into the race by rolling it down a hill. They placed fourth once. We do not like to discuss this.
2. EV-TO-TQ RATIO OPTIMISATION
The relationship between Engine Value and Tyre Quality is the single most critical performance variable on the circuit. An EV:TQ ratio exceeding 2:1 indicates the vehicle can generate more kinetic energy than the tyres can translate into controlled grip. This condition, known as "Friction Deficit," is the leading cause of high-speed lateral departures, involuntary off-road excursions, impromptu architectural assessments of concrete barriers, and the phrase "well, that was unexpected" being someone's final words.
WYC recommends maintaining an EV:TQ ratio no greater than 1.5:1 for standard operations. Naturally, most faction drivers ignore this recommendation entirely, which is why our replacement tyre division generates 340% more revenue than initial sales. Our Chief Financial Officer has described this business model as "beautiful" and wept openly during the last shareholder presentation. He was promoted.
The Honey Badger Berserkers, who routinely operate at ratios of 3:1 or higher, have formally requested that we stop publishing this recommendation, as they believe it is "making cowards of everyone." We have declined, as their catastrophic failure rate is responsible for approximately 22% of our total annual tyre sales and we would very much like them to continue.

4. THE EV 11 INCIDENT (REDACTED)
In 2041, the WYC Advanced Propulsion Lab attempted to construct an EV 11 powertrain. The project was codenamed "ABSOLUTE HUBRIS" — a name chosen by the lead engineer, who we are told had "a very dry sense of humour and an excellent pension that his family now enjoys."
The test was conducted in a reinforced bunker beneath the Nullarbor Plain. Upon ignition, the engine achieved an output so extreme that the test chassis completed the 400-metre test strip in 0.003 seconds, passed through the reinforced concrete blast wall largely intact, and was last detected by satellite approximately 14 kilometres downrange, travelling at a velocity that our physics team described as "rude."
The project has been indefinitely suspended. The crater has been converted into a staff car park.
5. CUSTOMER TESTIMONIALS
"I upgraded to EV 7 and it changed my life. Specifically, it made my life considerably shorter."
— Former Nocturnal Parliament Driver (anonymous, posthumous)
"The EV 9 powertrain is a masterpiece of engineering. I just wish I could have enjoyed it for more than eleven seconds."
— J. Weyland, Test Pilot (reconstructed)
