Premium Grill Review
Weber Summit S-670 Review: The Legacy 6-Burner Premium Gas Grill
The Weber Summit S-670 was Weber's flagship gas grill from approximately 2010 through 2022 — a 6-burner premium grill with 60,800 BTUs of total output, an integrated smoker box, infrared rotisserie burner, sear burner, side burner, and 769 square inches of cooking space. Originally priced at $2,399-2,899 MSRP, it competed with Napoleon Prestige Pro and DCS at the high end of residential gas grilling. Weber has since discontinued the S-670 in favor of the redesigned Summit Series, but the S-670 remains one of the best premium gas grills ever made. This review covers it honestly for existing owners, potential used-market buyers, and anyone researching what replaced it in Weber's current lineup.
60,800 BTUs. 6 burners. 769 sq in. Rotisserie + smoker box. Discontinued flagship.
Important note
The Weber Summit S-670 has been discontinued. Weber phased out the original Summit gas grill lineup (E/S-420, 470, 620, 670) around 2022 and introduced the redesigned Weber Summit Series with updated design, Crafted frame integration, and optional smart features. The S-670 remains one of the best premium gas grills Weber ever made. Existing owners — your grill is still excellent and replacement parts remain widely available. Used-market buyers — S-670s in good condition list for $1,200-1,800 (40-50% off original MSRP), which can be outstanding value. New shoppers — see the current Weber Summit Series for the direct successor.
Overall Score
The Verdict
The Weber Summit S-670 is one of the best premium gas grills ever made. 60,800 BTUs across 6 stainless burners, dedicated sear burner, flush side burner, infrared rotisserie, integrated smoker box with its own dedicated burner — this grill does everything. Now discontinued, but existing owners have an exceptional tool that will last 15-20+ years. Used-market buyers at $1,200-1,800 are getting premium-tier capability at mid-tier pricing.

What Made It Special
The 4 Features That Made the Summit S-670 a Premium Flagship
The S-670 cost 3-4x a Weber Spirit and 2-3x a Genesis. Here's what the premium price actually bought you — features that mid-tier grills simply didn't have.
Dedicated Smoker Box + Smoker Burner
Stainless steel smoker box built into the grill with its own 6,800 BTU dedicated smoker burner. Fill the box with wood chips, light the smoker burner, and add genuine smoke flavor to anything on the grill. This is NOT found on Spirit or Genesis tier grills. Turns the S-670 into a legitimate smoker for pork butts or chicken — without needing a separate dedicated smoker.
Tuck-Away Rotisserie System
Built-in 10,600 BTU infrared rear burner designed specifically for rotisserie cooking. The motor tucks away when not in use, with separate spit and fork storage inside the cart. Rotates at constant speed across the full 74-inch grill width — handles whole chickens, roasts, leg of lamb, or small whole pigs. Mid-tier grills require aftermarket rotisserie kits that don't integrate as cleanly.
Sear Station with Dedicated Burner
Center-mounted 10,600 BTU sear burner in addition to the 6 main burners. Activate it specifically when you want restaurant-quality sear marks on steaks. Delivers 700°F+ surface temperatures while the surrounding burners stay at normal cooking temps. Eliminates the need to turn all burners to high just for searing. Genesis tier also has sear burners but they're less powerful.
Flush-Mounted Side Burner
12,000 BTU side burner on the right side of the cart, integrated flush with the side table so it doesn't stick up. Cook sauces in cast iron pans, simmer side dishes, sauté vegetables — all without running inside to the stove. Full residential burner output (same as many home ranges). Premium feature that separates Summit from Genesis tier.
Performance Review
How the Weber Summit S-670 Actually Cooks
A $2,400+ grill needs to perform. Here's what the S-670 delivered (and still delivers for existing owners) across common cook types.
1. Primary Cooking (60,000 BTU, 624 sq in)
Six tapered burners produce 60,000 BTU combined — enough to preheat from cold to 500°F in 8-10 minutes and maintain high temperatures even with a lid full of food. Heat distribution edge-to-edge is excellent (within 10°F) thanks to the premium 9mm stainless rod grates which retain and redistribute heat better than thinner grates. The primary cooking area handles 18-20 burgers comfortably with room for buns — genuinely large-gathering capable.
2. Searing with the Sear Station
The 10,600 BTU dedicated sear burner at the center of the grill reaches 700°F+ on the grate surface when activated — genuine steakhouse territory. Running just the sear burner (with main burners off) concentrates heat in a specific zone for reverse-searing. Running all burners plus the sear burner delivers max heat across the full grate for fast cooks. The sear marks are pronounced — cross-hatch diamond patterns that make Instagram photographers happy.
3. Smoking with the Smoker Box
This is where the S-670 genuinely separates itself. The integrated smoker box + 6,800 BTU dedicated burner produces real wood smoke at low temperatures (150-250°F) — the S-670 handles pulled pork, ribs, and smoked chicken as capably as a dedicated smoker. Fill the box with hickory, apple, or oak chips, turn on just the smoker burner, and smoke for 4-8 hours. Capacity for a 7-pound pork butt or two rib racks on the main grate while smoking.
4. Rotisserie Cooking
The Tuck-Away rotisserie with 10,600 BTU infrared rear burner is the feature owners talk about most. Whole 5-pound chickens come out with crispy skin and juicy interiors in 90 minutes. Boneless pork loins, leg of lamb, or small whole pigs all work. The infrared burner browns the exterior evenly as the meat rotates, while the main burners (off during rotisserie) reflect heat back onto the meat. Professional-quality results impossible on mid-tier grills.
5. Long-Term Reliability (15-20+ year grills)
S-670 grills from 2010-2012 are routinely still in daily use in 2026 — 14+ years of reliability. The porcelain-enameled cook box essentially never fails. Stainless steel flavorizer bars last 10-15+ years. Main burners typically need replacement around year 8-12 ($85-120 each; typical DIY job). The Snap-Jet ignition modules may need battery replacement every 3-4 years. This is premium-tier longevity — these grills are designed to be passed down.
Then vs Now
Summit S-670 vs Current Weber Summit Series
Weber redesigned the Summit gas grill lineup around 2022-2023. Here's how the old and new generations compare for anyone choosing between them.
Discontinued Flagship
Weber Summit S-670
Original price: $2,399-2,899 MSRP
Current used price: $1,200-1,800
- • 6 main burners + sear + side + smoker + rotisserie burners
- • 769 sq in total cooking area
- • Integrated smoker box (unique feature)
- • 9mm stainless steel grates
- • No WiFi or smart features
Buy used if:
You want the integrated smoker box (not on current Summit). You find a well-maintained unit at $1,200-1,800. You're comfortable with older design aesthetics. You don't need WiFi.
Current Lineup
Weber Summit (Current Redesign)
Price: $2,999-4,499 MSRP
- • 4-6 main burners depending on variant
- • Weber Crafted frame compatibility
- • Updated aesthetic and redesigned cart
- • Optional WiFi and smart features
- • Current 10-year warranty
Buy new if:
You want the latest design and smart features. You want Weber Crafted accessory ecosystem. You want fresh warranty coverage. Budget allows $3,000+.
The integrated smoker box on the S-670 is actually something the current Summit Series doesn't have — Weber moved smoker box functionality to dedicated smoker products. If smoking on a gas grill matters to you, the used S-670 is uniquely capable. For everything else (design, smart features, Crafted accessory integration), the current Summit is the forward-looking choice.
Used Market Guide
Should You Buy a Used Weber Summit S-670 in 2026?
With the S-670 discontinued, the used market is where most shoppers encounter it. Here's the honest assessment.
Used Weber Summit S-670 grills at $1,200-1,800 (40-55% off original MSRP) can be exceptional values. The premium construction means even 10-year-old units have substantial remaining life if they've been covered and maintained. Weber's 10-year warranty transfers with original documentation for up to 10 years from original purchase date.
What to inspect when buying used:
Inspect Before Buying
Pre-purchase checklist
- Fire up all 6 main burners — each should light within 3 seconds of knob turn
- Test the sear burner separately (dedicated ignition)
- Test the side burner (separate valve)
- Test the rotisserie burner (check infrared glow develops)
- Test the smoker burner (often overlooked but critical feature)
- Inspect the cook box for cracks or major corrosion
- Check flavorizer bars — stainless should still look good, not warped
- Check cooking grates for warping (9mm rods should be straight)
- Verify all 4 casters roll smoothly
- Check the cart interior for rainwater damage (common issue)
- Ask for original purchase documentation for warranty transfer
Fixable vs Walk-Away
Know what you can repair
- FIXABLE: Burner replacement ($85-120 each), flavorizer bar set ($70-100), grates ($150-250), igniter module ($45-80), regulator ($25-40), rotisserie motor ($150-200)
- FIXABLE: Minor rust on cart exterior, missing rotisserie forks, missing side table brackets, worn wheels
- WALK AWAY: Cracked porcelain cook box, severely rusted firebox interior, warped lid that won't seal, major cart structural damage from rainwater
- BIG RED FLAG: Non-functional Snap-Jet ignition across all burners (likely wiring damage — expensive repair)
Typical total cost for used S-670 in good condition: $1,400 purchase + $150-300 in replacement parts (burners, flavorizer bars, or grates) = $1,550-1,700 total. Compare that to a new current Weber Summit at $2,999+ MSRP — the used route saves $1,300-1,500 for a grill that will still outperform most current mid-tier options on every capability except smart features.
FAQ
Weber Summit S-670 Frequently Asked Questions
Is the Weber Summit S-670 still available new in 2026?
No, Weber discontinued the original Summit gas grill lineup (including the S-670) around 2022 and replaced it with the redesigned Weber Summit Series. You may find remaining new-old-stock inventory at liquidation prices from some retailers (typically $1,600-2,200). Used units are widely available on Facebook Marketplace, Craigslist, and Weber's used listings at $1,200-1,800 depending on condition.
What's the difference between the S-670 and E-670?
Materials only. The Summit S-670 has 430-grade stainless steel hood, lid, and cart doors. The Summit E-670 has black porcelain-enameled steel on the same components. Everything else is identical — same 6 burners, same 60,000 BTU output, same cooking area, same features. The E-670 was $100-200 less expensive at MSRP. Both are now discontinued. S-670 has slightly higher used-market value due to stainless appearance.
Does the Summit S-670 really have a built-in smoker box?
Yes, and it's a feature that's genuinely unique among gas grills. The smoker box is a dedicated stainless steel chamber with its own 6,800 BTU burner. Fill the box with wood chips (hickory, apple, oak, pecan), turn on just the smoker burner, and produce real wood smoke at temperatures from 150-250°F. The S-670 can legitimately smoke pork butts, ribs, chicken, and fish — capabilities that most gas grills only approximate with smoker tubes or wood chip foil packets.
How does the Summit S-670 compare to the Genesis 335?
The S-670 is a tier above in virtually every spec. Genesis 335 has 3 main burners (39,000 BTU); S-670 has 6 main burners (60,000 BTU). Genesis 335 has 513 sq in cooking area; S-670 has 769 sq in. Genesis 335 has porcelain grates (or 7mm stainless on S-variants); S-670 has 9mm stainless grates. S-670 adds: smoker box, rotisserie burner, side burner, LED fuel scale, handle lights. Genesis 335 is a genuine mid-premium grill; S-670 was Weber's top-tier flagship.
Is a used Summit S-670 better than a new Genesis in 2026?
For many buyers, yes. A well-maintained used S-670 at $1,400-1,600 delivers premium-tier capability (smoker box, rotisserie burner, side burner, 9mm grates, sear burner) that a new Genesis E-335 at $1,299 simply doesn't have. The trade-off: you get older design aesthetic and no smart features, and you're buying a 10-year-old grill. If you value capability over design freshness, the used S-670 is usually the better pick.
How long does a Summit S-670 last?
20+ years with basic maintenance. S-670 units from 2010-2012 are still in daily use today in 2026 — that's 14+ years of reliable operation. The cook box and lid essentially never fail. Stainless flavorizer bars last 10-15 years. Main burners typically need replacement around year 8-12 (easy DIY replacement at $85-120 each OEM or $40-60 aftermarket). Cooking grates need replacement every 12-15 years. The Snap-Jet ignition may need modules replaced every 8-10 years. Nothing catastrophic typically fails — these are multi-decade grills.
What replaced the Summit S-670 in Weber's lineup?
The current Weber Summit Series (launched 2022-2023) is the spiritual successor. It's a redesigned lineup with updated aesthetic, Weber Crafted frame integration, optional smart features (WiFi, app integration), and similar premium positioning. Differences: the current Summit does NOT have an integrated smoker box (a downgrade for some buyers), has redesigned cart styling, and adds smart features. Price range: $2,999-4,499 depending on configuration.
Are replacement parts for the Summit S-670 still available?
Yes, widely. Weber continues to stock OEM replacement parts for discontinued Summit models through at least 2030. Aftermarket parts (burners, flavorizer bars, grates, igniter modules) are available from QuliMetal, Hongso, Uniflasy, and Weber directly. Common replacements: main burner tube ($85 OEM, $40 aftermarket), flavorizer bar set ($70-100 OEM, $40-60 aftermarket), cooking grate ($75-125 per grate), igniter module ($45 OEM). Most repairs are DIY-friendly in 15-30 minutes.
What's the best wood for the Summit S-670 smoker box?
Depends on what you're smoking. Hickory is the classic BBQ wood for pork and chicken — bold, slightly sweet. Apple is mild-sweet, good for chicken and pork. Oak is balanced and works with everything, especially beef. Mesquite is aggressive — best for short smokes or beef. Pecan adds subtle nuttiness to pork. For the smoker box, use chips not chunks (chips burn and produce smoke faster in the small box). Soak chips for 30 minutes before loading. Refill every 1-2 hours for extended smokes.
Should I buy the Summit S-670 used or wait for the current Weber Summit on sale?
Used S-670 is often the smarter buy in 2026. Even on Black Friday, the current Weber Summit rarely drops below $2,299 — $500-900 more than a well-maintained used S-670. The S-670 has the integrated smoker box that the current Summit doesn't have. Unless you specifically want Weber Crafted integration, smart features, or the newer aesthetic, the used S-670 delivers better capability-per-dollar. Exception: if you want fresh warranty coverage and don't want to deal with used-market inspection, the new Summit is worth the premium.
The Bottom Line
Final Verdict: Still One of the Best Premium Gas Grills Weber Ever Made
The Weber Summit S-670 is a legitimately excellent premium gas grill. 6 stainless burners, integrated smoker box, infrared rotisserie, sear burner, flush side burner, 9mm stainless grates — everything Weber could build into a gas grill was built into this one. Now discontinued, but still exceptional for existing owners and used-market buyers.
The S-670 was Weber's statement that they could build a premium gas grill to compete with Napoleon Prestige Pro, DCS, and Lynx at the high end of residential grilling. In terms of cook performance and feature set, the S-670 genuinely achieved that. Where it fell short was price-to-feature ratio — at $2,400-2,900 MSRP, it was priced similarly to higher-BTU competitors and lacked some premium materials (like full stainless steel carts). But for Weber loyalists, the S-670 delivered premium capability within the Weber ecosystem.
In 2026, the honest recommendations:
If you already own a Summit S-670: You own a genuinely premium gas grill. Maintain it, replace consumables as needed (burners every 10 years, flavorizer bars every 10-15 years, grates every 15+ years), and expect 20+ years of total use. The integrated smoker box is a feature the current Summit Series doesn't have — you have a capability that's hard to find on any current gas grill at any price.
If shopping used in 2026: The Summit S-670 at $1,200-1,800 delivers premium-tier capability at mid-tier pricing. Inspect carefully (especially rainwater damage in the cart and Snap-Jet ignition functionality), verify all burners fire reliably, and expect to spend $150-300 on replacement parts to refresh it. Total cost of $1,400-2,100 for a grill that will outperform most $1,500-2,500 current options.
If shopping new and premium-tier in 2026: The current Weber Summit Series is the direct successor. Different features (no smoker box, adds Crafted frame and optional smart tech), different aesthetic, higher base price. If you want modern design and smart features, it's the right pick. If you want the integrated smoker box, you'll need to buy a used S-670 or a separate Weber Smokey Mountain.
