Weight
The towing limit is exceeded by 325 kg!
It is not allowed to drive with this Coachman. Make sure the towing limit is correct.
We now give advice based on the assumption that the legal maximum towing weight is higher for your car and that the car should be allowed to tow this caravan!
The Renault Laguna Fase II 1.9 dCi with a Coachman Laser 640/4 with an actual weight of 1825 kg is not a recommended match to drive.
The motor preformance of the Renault is in general more than sufficient. But the weight of the Coachman with a User Payload (159 kg in the caravan and 200 kg in the car including passengers), is too heavy for long distances. Remember to load your caravan correctly, insuring that the noseweight of the caravan is sufficient and the weight is distributed properly. But even so, a starting caravan driver is better off choosing a smaller and less heavy caravan!

Renault Laguna Fase II 1.9 dCi Coachman Laser 640/4
Actual Weights
Coachman Laser 640/4: 1825 kg.
Renault Laguna Fase II 1.9 dCi: 1650 kg.
Noseweight: 100 kg.
Actual weight ratio: 111%.
Performance
The engine's performance is generally fairly good on flat roads (performance score to compare 191 points).
Speeds of 69 mph (111 km/h) to 74 mph (120 km/h) are often quite possible.
There is sufficient power at low engine speeds (score to compare 160 points).
Slightly higher revs (1900 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 24.5 sec.
In the mountains the performance is generally fairly good (score to compare 189 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 14%, but do require some experience from the driver.
On motorway inclines the speed drops despite high revs.
A speed of 58 mph (93 km/h) is usually possible on most motorway inclines.
Weight
The towing limit is exceeded by 325 kg (check this in your vehicle documents).
If you passed your driving test after 1 January 1997, you will need a B+E (or B96) driving license.
Weight ratio between the laden caravan and the loaded car is 111%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 126%.
The risk of snaking at higher speeds, strong side winds and thoughtless driving is great. It is not recommended to drive with this outfit for long distances!
Recommended noseweight is 100 kg.
Safe speed up to 50 mph (80 km/h).
Stability and safety score to compare is 33 points.
If the caravan starts to snake you should reduce your speed and slow down directly! Lift your feet off the accelerator and brake gradually. Hold the steering wheel into a fixed position.
Conclusion
Performance is more than sufficient.
Proper and careful loading is essential!
It's not a recomanded match. Only if you are an experienced (caravan) driver it is posible to drive carfully.
Influence of User Payload on stability
Weight distribution and noseweight are vital in obtaining a stable caravan.
