Napoleon Prestige 500 RSIB.
Premium 4-burner with 1,800°F infrared sizzle zone and 18,000 BTU rear rotisserie burner. 304 stainless build, 82,000 BTU total.
The Verdict.
Gavler Meta-Score
“Buy this if you sear more than you smoke and you want a grill that won't be embarrassed by your neighbor's $5,000 setup. The 1,800°F infrared side burner is the feature that separates serious gas grills from casual ones — it hits temperatures Weber's lineup can't match outside the Summit. The 304 stainless build is the long-term insurance: this grill will outlast most kitchens.”
