Why is the Haval's fuel consumption so high?
3 Answers
Haval's high fuel consumption is due to its relatively weak power output and its own heavy weight, which requires the engine to operate at high power. Here are some tips to reduce fuel consumption: 1. Lightly press the accelerator: The car consumes the most fuel during low-speed starts, so gently pressing the accelerator and avoiding high RPMs can effectively reduce fuel consumption. 2. Avoid high RPMs: Try to avoid unnecessary high RPMs, as fluctuating engine speeds can significantly increase fuel consumption. 3. Regular maintenance: Change the engine oil and remove carbon deposits. 4. Avoid sudden braking: Anticipating road conditions in advance not only improves driving safety but also saves fuel, such as slowing down gradually before traffic lights and using inertia to glide.
As a seasoned SUV specialist, the fuel consumption issue with Haval depends on several factors. The heavy body weight is the main culprit - models like the H6 use high-strength steel which improves safety but lacks sufficient weight reduction. The 1.5T engine struggles with such a large vehicle, especially in city traffic when the turbo isn't engaged, leading to significant fuel consumption. Many owners overlook tire pressure too - underinflated tires can easily increase consumption by 1L/100km. I recommend trying to drive at steady speeds with windows down and less AC usage - my highway tests show noticeable savings. The conservative tuning of older transmission models keeping RPMs stuck around 2000rpm is another issue. The newer models have improved aerodynamic coefficients, showing marked improvement.
After driving my Haval H9 for three years and covering 50,000 kilometers, I've realized that high fuel consumption isn't entirely the car's fault. When I first got it, the fuel consumption was a terrifying 14 liters per 100 km. Later, I learned to press the accelerator gently and avoid sudden braking, and now it's stabilized at 11 liters. The key is to understand the instantaneous fuel consumption bar—the green bar on the Haval dashboard is super practical! Try to coast as much as possible in traffic, and release the accelerator well before reaching a red light. Never delay maintenance; dirty spark plugs can increase fuel consumption by 10%. Once, I forgot to change the air filter and ended up burning two extra tanks of fuel—it was heartbreaking. Modifications require extra caution too; a roof rack can add an extra half liter per 100 km on the highway, and that's no joke.
