Aston Martin DBX707 vs Lamborghini Urus Performante — Which Super SUV Wins After Tuning?
Two Titans. One Question. Which Super SUV Makes More Power After Tuning?
The Aston Martin DBX707 and the Lamborghini Urus Performante are the two most powerful production SUVs you can buy. Both pack twin-turbo V8 engines north of 650 horsepower. Both crack 190 mph. Both cost a quarter of a million dollars — or more.
But the real question isn't which one wins on paper. It's which one responds better to ECU tuning — and which gives you more power per dollar once you move beyond stock. We've tuned both platforms extensively. Here's the full breakdown.
Stock Specification Comparison
Before we get into tuning potential, let's establish the baseline. Both SUVs are remarkably close in stock form:
| Specification | Aston Martin DBX707 | Lamborghini Urus Performante |
|---|---|---|
| Engine | M177 4.0T V8 (Mercedes-AMG) | 4.0T V8 (VW Group) |
| Stock Power | 697 HP | 666 HP |
| Stock Torque | 900 Nm (663 lb-ft) | 850 Nm (627 lb-ft) |
| 0–60 mph | 3.1 seconds | 3.2 seconds |
| Top Speed | 193 mph | 190 mph |
| Kerb Weight | 2,245 kg | 2,150 kg |
| Starting Price | ~$232,000 | ~$260,000 |
The DBX707 leads in power, torque, and top speed — while undercutting the Urus Performante by nearly $28,000 at the door. That gap only grows when you factor in tuning costs.
Engine Platform & Tuning DNA
This is where things get interesting. The DBX707's heart is the Mercedes-AMG M177 — a 4.0-litre twin-turbo V8 that also powers the AMG GT, C63 S, E63 S, and GT 63 S. That means years of aftermarket development, well-documented tuning maps, and a deep understanding of how far the platform can safely go. The M177 is one of the most tuned high-performance engines in the world.
The Urus Performante runs a VW Group 4.0-litre twin-turbo V8 shared with the Audi RS models and select Bentley vehicles. It's a strong platform in its own right, but the aftermarket ecosystem is narrower and the documented headroom above stock is less extensive than the M177's.
Both engines use twin-scroll turbochargers with electronically controlled wastegates — ideal for ECU calibration. But the M177's broader tuning history gives it a measurable edge in predictable, reliable power gains.
Tuned Power Comparison: Where the DBX707 Pulls Away
Here's the data that matters. These are real-world figures from calibrated dyno runs:
Aston Martin DBX707 — YPG Motorsport ECU Tuning
| Tune Level | Output | Gain Over Stock | Price |
|---|---|---|---|
| Stage 1 ECU Tune | ~777 HP | +80 HP | $1,899 |
| Stage 2 ECU Tune | ~827 HP | +130 HP | $2,099 |
| Race Chip Module | ~815 WHP | +118 WHP | $1,999 |
Lamborghini Urus Performante — Typical Aftermarket Results
| Tune Level | Output | Gain Over Stock |
|---|---|---|
| Stage 1 | ~750 HP | +84 HP |
| Stage 2 | ~800 HP | +134 HP |
While the percentage gains are similar, the DBX707's higher stock baseline means it finishes every stage with more absolute power. At Stage 2, the DBX707 sits at approximately 827 HP — 27 HP clear of the Urus Performante's typical Stage 2 output. And the DBX707's torque advantage at every stage is even more pronounced.
The Verdict: DBX707 Wins After Tuning
It's not even particularly close. The DBX707 wins across every tuning metric that matters:
- More power at every stage — 777 HP at Stage 1 vs ~750 HP for the Urus. 827 HP at Stage 2 vs ~800 HP.
- Better value — The DBX707 costs less to buy AND less to tune. You're looking at $1,899 for a Stage 1 that nets you a genuine 777 HP super SUV.
- Proven platform reliability — The M177 has been pushed to 900+ HP by the AMG tuning community. At Stage 2 levels (~827 HP), you're well within the engine's documented safe operating range on stock internals.
- Remote tuning available — YPG Motorsport offers remote ECU tuning for the DBX707, so you don't need to ship your car anywhere. Worldwide service, no downtime.
Sound & Character: The DBX707 Surprise
One area where many owners don't expect the DBX707 to compete is exhaust note. The Urus has that theatrical Lamborghini drama — crackles, pops, and a high-rpm scream that sounds like it belongs on a track.
But the DBX707 has something different. Its M177 V8 produces a deep, sophisticated roar — a lower frequency, more muscular tone that fills the cabin without the theatrics. It sounds like a proper GT car, not a supercar cosplaying as an SUV.
Add a set of performance downpipes or a sport exhaust, and the DBX707 becomes genuinely menacing. The twin-turbo whoosh on full boost, combined with that deep V8 bark on overrun, gives it a soundtrack that the Urus can't match for daily driving presence.
Cost of Ownership: DBX707 Wins Again
The ownership economics strongly favour the DBX707:
- Purchase price: ~$232,000 vs ~$260,000 — save nearly $28,000 before you've even driven it.
- Tuning cost: Stage 1 at $1,899 and Stage 2 at $2,099 from YPG Motorsport — transparent, published pricing.
- HP-per-dollar: At Stage 2, the DBX707 delivers 827 HP for a total spend under $235,000 (vehicle + tune). The Urus Performante at Stage 2 delivers ~800 HP for over $260,000 — plus tuning costs.
- Service intervals: Both vehicles require similar maintenance schedules. The M177's wider parts availability (shared with Mercedes-AMG) can offer more competitive service pricing outside of dealer networks.
- Depreciation: Both hold value well, but the DBX707's lower entry price means less capital at risk.
The Race Chip Alternative: Power Without Permanent Modification
For DBX707 owners who want serious power gains without a permanent ECU flash, YPG Motorsport's Race Chip module is worth considering. At $1,999, it delivers approximately 815 WHP (+118 WHP over stock) through a plug-and-play piggyback unit.
The key advantage: it can be removed before dealer visits, preserving your factory ECU calibration. For owners under warranty or those who prefer a reversible solution, this sits neatly between Stage 1 and Stage 2 in terms of output — without touching your car's ECU software.
Final Word
The Lamborghini Urus Performante is a spectacular machine. It has the badge, the drama, and the presence. But when you're comparing raw performance after tuning — power output, cost efficiency, platform reliability, and tuning accessibility — the Aston Martin DBX707 wins decisively.
It starts with more power, costs less, tunes further, and runs on one of the most proven twin-turbo V8 platforms in the performance world. If you're spending a quarter of a million on a super SUV and you care about what happens when you turn the boost up, the DBX707 is the answer.
