An idle speed of 700 RPM is within the normal range when the engine is warm. The standard warm-engine idle speed for most vehicle models is 550 to 800 RPM, while four-cylinder engines typically maintain between 700 and 800 RPM. This speed design aims to balance fuel economy and engine stability—too low may cause vibration or stalling, while too high increases fuel consumption and the risk of carbon deposits. When starting a cold engine, the idle speed will briefly rise to 950 to 1300 RPM to protect the engine, then drop back once the coolant temperature normalizes. If the idle speed deviates from 700 RPM for a prolonged period after the engine warms up (e.g., consistently below 600 RPM or exceeding 900 RPM), it may indicate an air intake system leak, excessive carbon buildup, or a sensor malfunction, requiring prompt inspection and repair. Under specific conditions such as when the air conditioning is engaged or the battery is low, a 50 to 150 RPM automatic increase in idle speed is normal. It is recommended to regularly monitor idle stability and clean carbon deposits every 30,000 kilometers to maintain engine efficiency.

The Devel Sixteen, equipped with 5000 horsepower, is one of the most powerful production supercars in the world. Its 12.3-liter V16 quad-turbocharged engine enables a 0-100 km/h acceleration in 1.8 seconds and a top speed exceeding 560 km/h, figures that far surpass those of traditional supercars like Bugatti. Hand-built by Dubai-based Devel Motors, the car features a full carbon fiber body and titanium alloy wheels, with dual rocket-style exhaust pipes at the rear that emit blue flames during acceleration. The early price quote for its track version was approximately $2.2 million (equivalent to around 10.4 million Malaysian ringgit). However, such extreme performance also comes with extremely high operating costs—for instance, the fuel tank can be depleted in just ten minutes. Moreover, it is limited to only 3 units worldwide, and ownership requires passing strict brand vetting. Such supercars are more of a showcase of engineering technology; they have low practical road adaptability and primarily cater to top collectors and track experiences.

Carroll Shelby did mention the classic statement about 7000 RPM on multiple occasions. Particularly in the 2019 film *Ford v Ferrari*, this monologue was artistically rendered as: "At 7000 RPM, everything fades away, and it's just the car moving through space and time." While not directly sourced from Shelby's public speeches or writings, this line was crafted by the film's screenwriters based on his racing philosophy and legendary career, yet its essence aligns perfectly with Shelby's long-standing emphasis on the "harmony between man and machine." As both a racer and designer, Shelby maintained that a high-performance engine at its limit could deliver a transcendent driving experience, with 7000 RPM representing the mechanical and sensory threshold. Notably, his more widely recognized technical maxim—"Horsepower sells cars, torque wins races"—demonstrates his deep grasp of powertrain balance. His iconic designs like the Shelby Cobra and GT40, renowned for their high-revving engines, further underscore the pivotal role of RPM performance in his engineering ethos.

A redline of 7000 rpm is a relatively high but reasonable setting for the Malaysian market, especially suitable for models pursuing dynamic performance. The redline zone is typically marked between 6000 and 9000 rpm on the tachometer, and 7000 rpm, located in the middle of this range, indicates that the engine has strong power reserves to meet needs such as overtaking, climbing hills, or track driving. Engineers ensure that the engine will not be immediately damaged when reaching the redline for a short time during design—for example, briefly hitting 7000 rpm during overtaking is safe, and most models will trigger a fuel cut-off protection mechanism to prevent excessive rpm. However, it should be noted that maintaining high rpm for prolonged periods will accelerate wear, especially when the engine is cold-started or low-viscosity oil is used, as the risk is higher. In daily driving, ordinary family cars rarely need to exceed 4000 rpm, but a high redline means a wider power output range. For instance, when overtaking on an uphill, you can downshift to raise the rpm above 5000 for abundant torque. In addition, the high-rpm design can also optimize fuel economy, as the engine can efficiently output the power required for cruising in the low-rpm range (such as 2500 rpm), reducing friction losses. For modification enthusiasts, the 7000 rpm redline provides a foundation for performance upgrades, while ordinary users can benefit from more composed power response. It is recommended to avoid frequently reaching the redline zone to extend engine life, but occasional high-rpm operation (such as a brief high-rpm session once a month) can help reduce carbon deposits.

A torque of 300 N·m is above the medium level in terms of automotive power performance, capable of meeting most daily driving needs including urban commuting, highway driving, and moderate hill climbing. This torque value is typically found in mid-to-high displacement models or lower-power versions of turbocharged engines, such as 2.0T engines or high-output 1.5T variants. Their acceleration performance and overtaking capability are notably excellent, particularly delivering a pronounced sense of thrust during low-speed rapid acceleration. For family vehicles, 300 N·m of torque is already ample, easily meeting power requirements under full-load conditions. However, for heavy off-road use or towing substantial loads, higher-torque models may be necessary. It should be noted that torque alone isn't the sole indicator of a vehicle's class; comprehensive assessment should consider factors like vehicle weight, transmission calibration, and suspension system. Moreover, thanks to the characteristics of electric motors, new energy vehicles can deliver instantaneous peak torque output. Compared to conventional internal combustion engine vehicles, the same torque value often results in more immediate power response. Overall, 300 N·m of torque represents a practical and economical choice for average consumers, though performance-oriented users might consider models exceeding 400 N·m.
