Both are high-quality Weber grill series, but there are some key differences between them.

Read on to find out more about the similarities, differences, and features of the gas grills from both gas grill lines.

Weber Spirit vs. Genesis – Overview

Manufacturing and design


All Weber grills are made in America but with components that are made in Taiwan in China. The only grill which is entirely USA-made is the Weber Smokefire. Still, Weber prides itself on making top-quality grills – the Spirit and the Genesis series are examples of this.

Both series include a variety of individual grills of all ranges and sizes, and now they have a new second (II) generation of grills available as well.

Compared to the Genesis grills, the Weber Spirit line of grills is designed and made as a barebone starter grill for occasional use as well as for newbies. Still, they are excellent grills. The Genesis grills are more advanced, with more “bells and whistles,” making them suitable for true enthusiasts and advanced grillers.

The Weber Spirit gas grills are available in sizes ranging from 2-burners and up, while the Genesis grills start from the smallest 3-burner models and reach the high-end 6-burner gas grill – the Genesis II SP-435.

For the purposes of this article, we will be focusing on two of the most popular Spirit grills – the first-generation Weber Spirit E-310 and the Weber Spirit E-330. We will be comparing them with the Genesis II E-310 and with Genesis II E-330 gas grills.

Main similarities


The gas grills from the new second generation of the Weber Spirit and the Genesis series have a lot of similarities, including:

  • All grills are backed by Weber’s 10-year warranty
  • They feature the Weber G4S Grilling System, which includes Infinity Ignition, Flavorizer Bars, Advanced Grease Management, and Upgraded Burners
  • All of these grills are compatible with the Weber iGrill 3 technology, allowing for remote monitoring and control of the temperatures and the cooking
  • All of the individual grills from both series come in different color options, namely black and stainless steel. The more colorful options are available only for the smaller models
  • Both series have a second-generation line of grills introduced in 2018-2019

Main differences

While the Weber grills from the Spirit and Genesis lines share some of the best features offered by Weber, there are some key as well as some more subtle differences between the individual gas grills of both lines, including:

  • The Weber Spirit gas grills are considered “starter grills” and, as such, are less expensive than the more advanced grills from the genesis series
  • The Genesis grills have more “bells and whistles,” including extra burners, sear stations, enclosed carts, and other advanced features and attachments
  • The Genesis gas grills typically have more burners with a higher BTU output than the grills from the Spirit line

GS4 grilling system

As mentioned previously, all of the gas grills from the newer generation of both series feature Weber’s G34 Grilling System. This system consists of four main components, including:

  • Infinity Ignition – with heavy-duty coating for the wires, easy to replace batteries, a protected ignition module, and more reliable electrodes
  • Flavorizer Bars – triangular bars which are fitted under the cooking surface which deflect the grease and juices from the meat and thus prevent them from reaching the burners and causing flare-ups. At the same time, these bars help sizzle the grease and juices, creating smoke and sizzling and adding more flavors to the food
  • Upgraded Burner Tubes – Weber now uses better burner tubes than the previous models. The new burner tubes are reversible and tapered and disperse the heat evenly throughout the cooking surface, preventing cold or hot spots.
  • Advanced Grease Management – the gas grills have an easy-to-remove and clean grease pan which captures any grease and juice which manages to make it through the flavorizer bars

Make sure that you check whether the grill of your choice has this Grilling System because some of the older models do not feature it.

IGrill Technology

All of the individual gas grills from the new generation of the Spirit and the Genesis series are compatible with Weber’s iGrill 3. This is the company’s Bluetooth meat thermometer. It can be connected wirelessly to a smartphone, and thus you can monitor the internal temperature of up to 4 pieces of meat without opening the grill’s lid.

The mobile app will also alert you when the desired doneness temperatures are reached. Keep in mind, that you will need to buy the iGrill 3 thermometer separately if you want to use it. Check the model you choose for iGrill 3 compatibility, because the technology was included only several years ago, and older grills may not have it.
