Ground clearance is one of the key parameters affecting comfort and safety of operation Nissan Sunny. This topic is especially relevant for Russian drivers, where the quality of roads leaves much to be desired. Depending on generation and modification Sunny ground clearance varies from 140 to 170 mm, which is not always enough to overcome deep holes or snow drifts.
In this article we will analyze in detail the official and real ground clearance indicators for all generations Nissan Sunny (B13 to B17), including export versions. You will learn how to correctly measure the clearance yourself, what factors influence its reduction, and what methods of increasing clearance really work - from installing spacers to replacing springs. We will also compare Sunny with the main competitors in the class and give practical recommendations on choosing tires and wheels for optimal ground clearance.
Official data: Nissan Sunny ground clearance by generation
The manufacturer indicates the clearance for Nissan Sunny in the technical specifications, however, these figures often differ from actual measurements. Below is a table with official data for the main generations produced in different markets:
| Generation | Years of manufacture | Ground clearance (mm) | Notes |
|---|---|---|---|
| B13 | 1990–1995 | 150–160 | Depends on market (Japan/Europe). Sedans are 5–10 mm lower than hatchbacks. |
| B14 | 1995–2000 | 155–165 | Versions with automatic transmission have 5 mm less clearance. |
| B15 | 2000–2006 | 160–170 | Maximum ground clearance for all-wheel drive versions (4WD). |
| B16 (Asia) | 2006–2012 | 150–160 | Lowered to improve handling. In Russia it was sold as Almera Classic. |
| B17 (Sunny for Middle East) | 2011–2020 | 165–175 | Adapted for bad roads. Not officially supplied to Russia. |
It is important to consider that real ground clearance may differ from factory data by 10–20 mm due to wear of the suspension, installed wheels or additional equipment (for example, crankcase protection). For example, after 100,000 km, the springs sag by an average of 10–15 mm, and the rubber silent blocks lose their elasticity, which also reduces ground clearance.
⚠️ Attention: If you are buying used Nissan Sunny, be sure to measure the ground clearance in the center of the front bumper and under the engine compartment. A difference of more than 20 mm between these points may indicate damage to the subframe or deformation of the body after an accident.
How to correctly measure ground clearance yourself
For precise measurement of ground clearance Sunny you will need a level surface, a ruler or caliper, and an assistant. Follow this algorithm:
- Place the car on a flat surface (no slope) with an empty trunk and interior (the driver's weight is acceptable).
- Inflate your tires to the manufacturer's recommended pressure (usually 2.0–2.2 bar).
- Measure the distance from the ground to:
- 🔹 Lower edge of the front bumper (center).
- 🔹 Oil pan (oil plug).
- 🔹 Rear suspension beams (center).
- 🔹 Door thresholds (to assess body geometry).
Compare the obtained values with the factory ones. If the difference exceeds 15–20 mm, this is a reason to check the suspension. For example, sagging of the front Sunny B14 is often associated with worn bearings or springs, and rear settlement may indicate leaky shock absorbers.
If you don't have a caliper, use a wooden ruler and level for construction work. Place the ruler horizontally under the bumper, and then measure the distance from the ground to its top edge with a regular tape measure.
Comparison of Nissan Sunny ground clearance with competitors
In the class of compact sedans and hatchbacks Nissan Sunny traditionally occupies an average position in terms of ground clearance. For clarity, let’s compare it with its main rivals:
- 🚗 Toyota Corolla (E120/E170): 150–160 mm - similar Sunny B14, but with a stiffer suspension.
- 🚗 Honda Civic (EG/EK): 135–145 mm – 10–20 mm lower, which affects cross-country ability.
- 🚗 Mazda 323 (BJ): 155–165 mm - comparable to Sunny B15, but with better geometric cross-country ability.
- 🚗 Hyundai Elantra (XD): 160–170 mm is the leader in ground clearance in the class, but is inferior in suspension reliability.
- 🚗 Volkswagen Jetta (A4): 140–150 mm is the lowest in comparison, but with better directional stability.
I wonder what Nissan Sunny B17 (for the Middle East) with a ground clearance of 175 mm surpasses even some crossovers in the budget segment, for example, Renault Duster first generation (205 mm). However, this is achieved at the expense of higher springs and soft suspension, which negatively affects handling at high speeds.
- 140–150 mm
- 150–160 mm
- 160–170 mm
- More than 170 mm
Why clearance decreases: main reasons
Even with careful use, ground clearance Nissan Sunny decreases over time. Here are the key factors influencing this:
- 🔧 Spring wear: After 80–100 thousand km, the metal loses its elasticity, the springs “shrink” by 10–30 mm. This happens especially quickly with frequent overloads or off-road driving.
- 🔧 Shock absorber sag: The oil in the struts degrades, which leads to uneven settlement of the body. For example, if the front left pillar is “broken,” the ground clearance on this side will decrease by 15–25 mm.
- 🔧 Suspension arm deformation: After strong impacts (for example, hitting a curb), the arms can bend, changing the geometry and reducing clearance.
- 🔧 Wear of silent blocks: Rubber bushings lose their elasticity, which leads to displacement of suspension elements and a decrease in ground clearance by 5–10 mm.
- 🔧 Installation of non-standard wheels: Wheels with an offset (ET) that are smaller than the factory one or tires with a high profile can touch the arches, forcing you to reduce the pressure - this additionally “sits” the car.
Critical information: If after replacing the springs or shock absorbers the ground clearance has not been restored, check the condition of the support cups and subframe. Their deformation (even by 2–3 mm) can negate all efforts to restore ground clearance.
How to check shock absorbers without removing them?
Press the car fender with a force of 20–30 kg and release. If the body oscillates more than 1-2 times, the strut is faulty. Also pay attention to oil smudges on the shock absorber body - this is a sign of wear on the seals.
Ways to increase clearance: what really works
If the factory ground clearance Nissan Sunny is not enough, it can be increased in several ways. Let's consider their effectiveness and risks:
1. Installation of spacers
The most budget method (from 1,500 rubles). Spacers made of polyurethane or aluminum are installed between the body and the racks (springs). Pros:
- ✅ Quick installation (1-2 hours).
- ✅ Possibility to choose the height (from 10 to 50 mm).
Cons:
- ❌ Deterioration in controllability (increases roll in turns).
- ❌ Risk of damage to CV joints when lifting by more than 30 mm.
2. Replacing springs with reinforced ones
The best option for Sunny B13–B15. Springs with increased stiffness (for example, from Nissan Primera P12) raise the ground clearance by 15–25 mm without loss of controllability. Cost: 8,000–12,000 rubles. per set.
3. Installation of air suspension
Expensive (from 50,000 rubles), but the most universal solution. Allows you to adjust the ground clearance on the fly from 140 to 200 mm. Suitable for Sunny B15/B17 with powerful motors (eg SR20DE).
4. High profile tires
Replacing standard tires 185/65 R14 on 195/70 R14 increases ground clearance by 10–12 mm. It is important to check that the wheels do not touch the arches when the steering wheel is turned completely.
⚠️ Attention: When raising the ground clearance by more than 30 mm, be sure to check the wheel alignment angles and adjust them if necessary. Otherwise, the tires will wear unevenly and the steering will become stiff.

The influence of ground clearance on handling and safety
Increased ground clearance Nissan Sunny inevitably affects the behavior of the car on the road. Let's look at the key aspects:
- 🚗 Center of gravity: A rise of 20–30 mm shifts the center of gravity upward, which increases roll in corners by 10–15%. This is especially noticeable on Sunny B14 with a short wheelbase.
- 🚗 Aerodynamics: Ground clearance of 170+ mm reduces downforce at speeds above 120 km/h, which can lead to poor directional stability when overtaking.
- 🚗 Suspension load: Reinforced springs or spacers increase the load on struts and levers by 15–20%, reducing their service life.
- 🚗 Braking distance: When climbing 40+ mm, the braking distance increases by 5–7% due to changes in the geometry of the brake mechanisms.
On the other hand, increased ground clearance improves:
- 🔹 Passability in snow (the depth of the snow cover to be overcome increases by 20–30%).
- 🔹 Protection of the crankcase and gearbox from impacts on uneven surfaces.
- 🔹 Comfort on broken roads (less suspension breakdowns).
For a balance between cross-country ability and controllability, we recommend:
- 🔧 Raise the ground clearance by no more than 20–25 mm.
- 🔧 Use springs with progressive stiffness (for example, TEIN or KYB).
- 🔧 Install crankcase protection with ground clearance less than 160 mm.
Optimal ground clearance for Nissan Sunny in Russian conditions - 160–170 mm. This is sufficient for most roads and is not critical for handling.
Selecting tires and wheels for optimal ground clearance
Wheels directly affect ground clearance. For Nissan Sunny The following recommendations are relevant:
Discs
Factory parameters:
- 🔄
14×5.5Jwith departureET40–45and PCD4×100. - 🔄
15×6Jfor modifications with enginesGA16DEAndSR20DE.
When selecting non-standard disks:
- 🔹 Departure (
ET) should not differ from the factory one by more than ±5 mm. - 🔹 Rim width - up to 7J (otherwise you will need to roll out the arches).
Tires
Recommended sizes to increase ground clearance:
| Standard size | Alternative size | Increased clearance | Notes |
|---|---|---|---|
175/70 R13 |
185/70 R13 |
+5 mm | Suitable for Sunny B13. |
185/65 R14 |
195/70 R14 |
+12 mm | Requires checking for interference with arches. |
195/55 R15 |
205/60 R15 |
+10 mm | Only for Sunny B15 with motor QR20DE. |
When installing high profile tires:
- 🔹 Check the gaps in the arches with the steering wheel fully turned and the suspension loaded.
- 🔹 Keep in mind that tires with a profile height of more than 70% impair steering accuracy.
- 🔹 Narrow tires are preferable for winter (for example,
185/70 R14), since they “cut” into the snow better.
FAQ: Frequently asked questions about Nissan Sunny ground clearance
Is it possible to drive with a ground clearance of 140 mm on Russian roads?
Technically it is possible, but this is fraught with constant breakdowns of the suspension and the risk of damage to the crankcase. For Sunny B13/B14 The minimum recommended ground clearance is 150 mm. With less clearance, avoid holes deeper than 5 cm and install engine protection.
What is the ground clearance of the Nissan Sunny with the SR20DE engine?
For Sunny B14/B15 with motor SR20DE factory ground clearance is 155–160 mm (5 mm less than versions with GA16DE, due to the greater weight of the engine). After 100,000 km it decreases to 140–145 mm.
How much do spacers cost to increase ground clearance?
The price depends on the material and height:
- Polyurethane (10–20 mm) — RUB 1,500–2,500.
- Aluminum (20–30 mm) — RUB 3,000–5,000.
- Pneumatic (adjustable) - from 20,000 rubles.
Installation at the service will cost 1,000–1,500 rubles.
Does ground clearance affect fuel consumption?
Yes, but only slightly. Increasing the clearance by 20–30 mm worsens aerodynamics, which can increase consumption by 0.3–0.5 l/100 km at speeds above 90 km/h. On the urban cycle the difference is unnoticeable.
Which springs are best for raising ground clearance?
For Nissan Sunny we recommend:
- TEIN S-Tech — rise by 15 mm, stiffness +20%.
- KYB Excel-G — restoration of factory ground clearance, resource 100+ thousand km.
- Eibach Pro-Kit — reduction by 15 mm (for sporty driving).
Springs from Nissan Primera P12 (front) and Almera N16 (rear) also suitable for 20mm lift.
