This Napoleon gas grill features an electronic ignition on the front of the unit. The JETFIRE ignition system makes starting the grill quick and easy. You press down on the button, and the battery builds up a charge and then sends a series of sparks to the burners to ignite the gas. Electronic ignitions are an efficient way to get the flame going, but they also require a battery, which needs to be replaced occasionally. In our tests, this was one of the fastest heating grills, heating to 500 degrees Fahrenheit in about three and a half minutes. It also did a fairly good job of retaining heat.

The Mirage is available as a propane or natural gas unit. Once you have the natural-gas pipeline installed, you no longer have to worry about running to the closest gas station to fill up your depleted propane tank in the middle of a BBQ party.

Infrared technology is a good way to grill meat at high temperatures to sear meat and caramelize the outside. The Mirage comes with an infrared side burner that features a ceramic infrared heating plate and burner in the rear of the unit. This gas BBQ grill is one of the few mid-range grills we found that features a rear infrared burner. You can also buy a heavy-duty rotisserie kit separately to slow-cook chicken or roast. This extra feature opens up new possibilities in grilling, and it's one of the reasons this is one of the best gas grills in our review.

BTUs measure how much fuel a grill is likely to consume during use. The higher the BTU, the more heat it is likely to generate in a short time. Grills that heat quickly can also use up more fuel than average. The three primary burners on the Napoleon Mirage can generate up to 74,000 BTUs. The side burner generates up to 12,500 BTUs on its own, and the rear rotisserie grill can generate up to 13,500 BTUs.

Grilling Areas & Dimensions

The space provided for primary grilling is a little below average, but the infrared burners help make up for it. We were able to fit 20 burgers on the grill at once, which should be plenty for most occasions. The warming tray fit up to eight buns. The warming trays are good for melting cheese on your burgers or keeping vegetables warm. The infrared side burner adds additional cooking space that is also nice for cooking vegetables. You can slow-roast meat using the infrared grill in the back.

Another nice feature of this gas grill is its integrated ice bucket and cutting board on the side shelf. You just flip the lid of the side shelf over and you have a sturdy cutting surface. Under the lid, you'll find a space where you can add ice to keep your drinks or meat cold. The Mirage also has the rare feature of letting you opt for charcoal. While they aren’t necessities, these features that help set the Mirage apart from the other grills.

This gas grill has backlit control knobs for grilling at night. The iGlow knobs have an ergonomic design that make it easy to grill in the dark without having to squint to see the temperature settings. Napoleon also offers an optional halogen light that you can attach to the side of the unit.

The Lift Ease roll-top lid is also handy because it decreases the amount of space the grill takes up. Many grills need to have a few extra inches of clearance so you can lift the lid all the way up. The lid on this grill rolls forward as it lifts, so the lid is almost flush with the back of the grill.

Grill Construction

Inside this grilling machine, you will find sear plates, cooking grids and three burners, all made of stainless steel. The lid, side shelf and cabinet doors are also made of stainless steel, which means that your grill will last a long time. Stainless steel is a very durable material – it will not rust, and it resists damage from food and cleaning. In our experience, cast-iron grates usually retain heat slightly better than stainless steel grates, with more even cooking, but you can’t go wrong with stainless steel either.

Napoleon grills have unique WAVE cooking grates that leave a distinct sear pattern on your meat. The grill also has a unique wrap-around condiment tray so you have a designated place to put your sauces and spices. There is plenty of storage space with this grill for all of your accessories.

The Napoleon grill won't take up a lot of room on your deck or porch, which is great. With the lid closed, this gas grill measures 59.25 inches high, 61.75 inches wide and 27.25 inches deep. It is one of the biggest grills in our lineup, yet it is one of the lightest at just 80 pounds. It is easy to maneuver around your deck space with its heavy-duty casters on the bottom.

Warranty & Support

This Napoleon grill has one of the best warranty packages of any grill out there. The burner comes with a limited lifetime warranty, and the parts come with an impressive five-year warranty.

We were impressed with the customer support team at Napoleon. We contacted them a number of times and received prompt, friendly and informative responses. If you have any problems or questions about your Napoleon grill, you can be confident in the support you will receive from Napoleon’s customer support.

In addition to excellent email and phone support, Napoleon also has informative FAQs on its website that provide tips on grill assembly, general grill care and methods of grilling. On the Napoleon gas grills website, you can also find a troubleshooting guide, a maintenance guide, maintenance videos and more.


With the Napoleon Mirage LEX485RSIB, you get a handy hybrid of traditional and infrared technologies. In addition, you can fuel this grill with either propane or natural gas to fit your current setup. It has several extras like the backlit knobs, integrated cutting board and ice chest. It heats up quickly and heats evenly for the most part, though we found it didn’t retain heat as well in front as it does in the middle and rear of the primary grilling area. The infrared side and rear burners are a nice addition that give it more versatility when it comes to options for cooking your meat. This grill gives you all kinds of extras, and the overall grilling experience is great. The Napoleon Mirage is one of the best grills in its price range.
