When you walk onto a dealership floor, the top‑end model often grabs your attention first. A V10 roaring under a sleek bonnet, an eye‑catching badge, and a price tag that screams exclusivity – it’s easy to assume that more power automatically means a better driving experience. But as any seasoned enthusiast knows, the fastest variant can also be the most demanding, the most expensive to run, and sometimes, simply the wrong fit for everyday life.
Introduction: The Myth of “More Is Better”
My love affair with performance cars began with a modest BMW 520d that I once mistook for an unassuming sedan. A closer look revealed a hidden BMW 550i – a vehicle that offered the comfort of a luxury sedan with the heart‑pumping power of an M5, yet without the latter’s quirks. Stories like this illustrate a broader truth: the highest‑spec model isn’t always the most practical, nor the most enjoyable in the long run.
The Allure of the Fastest Model
Manufacturers love to showcase their flagship – the M5, the Golf R, the Audi R8 V10. These cars are engineering marvels, often equipped with the latest ADAS (advanced driver‑assistance systems), carbon‑fiber interiors, and turbo‑petrol or hybrid powertrains that push the limits of speed. The excitement is real: a 5.0‑litre V10 screaming 560 hp, a launch control that catapults you from 0‑60 mph in under four seconds, and a badge that guarantees envy on the road.
However, that very performance can bring hidden drawbacks:
- Fuel thirst – the original 2005 M5 needed a stop at the pits every 180 miles because of its insatiable appetite for super‑unleaded fuel.
- Complexity – high‑revving V10s, dual‑clutch paddle shifters, and intricate electronic systems demand specialised maintenance.
- Weight – added carbon‑fiber panels, larger brakes, and reinforced chassis often make the flagship heavier than a lower‑spec sibling.
- Attention magnet – flashy badges attract thieves, vandals, and insurance premium spikes.
Hidden Costs of Speed
Owning a hyper‑performance model is not just about the purchase price. The ongoing costs can dwarf the initial outlay. Here’s a quick snapshot comparing the BMW M5 (latest generation) with its more subdued cousin, the BMW 550i:
| Aspect | BMW M5 | BMW 550i |
|---|---|---|
| Engine | 4.4‑L twin‑turbo V8 (625 hp) | 4.4‑L twin‑turbo V8 (462 hp) |
| 0‑60 mph | 3.3 s | 4.7 s |
| Fuel economy (combined) | 22 mpg | 27 mpg |
| Annual maintenance (est.) | £2,200 | £1,350 |
| Insurance (average UK) | £1,800 | £1,200 |
The numbers speak for themselves: the 550i delivers ample power for most drivers, better fuel range, and noticeably lower running costs.
When the ‘Second Best’ Wins
Consider the Volkswagen Golf GTI versus the Golf R. The GTI’s 2.0‑litre turbo‑petrol makes 241 hp, while the R pushes 315 hp and adds all‑wheel drive. Both are brilliant, but the GTI is lighter, cheaper to insure, and easier to service. For daily commuting, weekend track days, and even spirited mountain passes, the GTI often feels more balanced.
Another classic: the Peugeot 205 XS over the legendary 205 GTI 1.6/1.9. The XS’s 1.4‑litre rev‑hungry engine, close‑ratio gearbox, and lighter chassis deliver pure, row‑by‑row excitement without the brute‑force torque of its GTI cousins.

| GTI | £30,000 | £28,500 | ≈ 32 % |
| Golf R | £38,000 | £36,000 | ≈ 35 % |
Rarity, Resale Value, and the ‘Underdog’ Effect
Interestingly, the ultra‑exclusive models often survive longer on the road simply because they are collected, not driven hard. The UK currently has about 6,300 M5s across all generations but only 511 550is – and just 22 of those are the rare E61 Tourings. That scarcity makes the 550i a coveted sighting for enthusiasts who value uniqueness over sheer horsepower.
In the same vein, the Audi R8 V8 (first generation) remains more sought after than the later V10 variant for many purists. The V8 is lighter, less frantic, and offers a more “driver‑focused” experience, proving once again that less can be more.
Practical Advice: Choosing the Right Balance
If you’re torn between a flagship and its lower‑spec sibling, ask yourself a few practical questions:
- How often will you push the car to its limits?
- What’s your annual mileage and fuel budget?
- Do you need the extra tech (e.g., advanced ADAS) or will a simpler setup suffice?
- Is the vehicle a daily driver, a weekend toy, or a future collectible?
Answers to these questions often point toward the “second best” – a model that delivers excitement, reliability, and lower ownership costs without the headaches of the absolute fastest version.
Conclusion: Speed Isn’t the Whole Story
The romance of the fastest car is undeniable, but the smartest enthusiasts know that the best car for them balances power, practicality, and personality. Whether it’s the BMW 550i over the M5, the VW Golf GTI over the Golf R, or the classic Peugeot 205 XS over the GTI, the under‑dog often offers the most rewarding ownership experience.
So next time you’re eyeing that top‑end badge, remember: a slightly slower, lighter, and cheaper-to‑run model might just give you more joy, more miles, and fewer trips to the garage. After all, true automotive pleasure is measured in moments behind the wheel, not just in a number on a spec sheet.
FAQ
- 1. Is a faster car always more expensive to insure?
- Generally, yes. Higher horsepower, lower weight, and a performance badge increase perceived risk, leading insurers to charge higher premiums.
- 2. Do flagship models have better resale value?
- They can, but rarity plays a bigger role. A limited‑run M5 may hold value better than a more common 550i, yet the 550i’s lower purchase price often results in a lower absolute depreciation.
- 3. How much more fuel does a V10 consume compared to a V8?
- On average, a V10 can be 10‑15% thirstier than a similarly tuned V8, especially when driven aggressively.
- 4. Are lower‑spec models less reliable?
- Not necessarily. Simpler engines and fewer electronic aids usually translate to fewer failure points, often enhancing reliability.
- 5. Does ADAS work better on high‑performance cars?
- ADAS systems are calibrated for the vehicle’s dynamics. While they function on any model, the calibration on a flagship may be tuned for higher speeds, offering marginally quicker response times.
- 6. What’s the advantage of a manual gearbox over a paddle‑shift?
- Manuals give drivers full control over shift points, fostering engagement. Paddle shifters provide rapid shifts but can feel less connected.
- 7. Should I consider a turbo‑petrol engine over a diesel for everyday use?
- Turbo‑petrol engines tend to be smoother, cheaper to maintain, and emit less NOx, making them a sensible choice for most daily drivers.
- 8. Is the VW Golf GTI really a better value than the Golf R?
- For most drivers, yes. The GTI offers similar chassis dynamics with lower running costs and a lighter weight, which often translates to more fun per pound.
- 9. How does vehicle weight affect performance?
- Every kilogram matters. A lighter car accelerates faster, brakes shorter, and handles more nimbly, often offsetting a modest power deficit.
- 10. Where can I read more about the M5 vs 550i debate?
- Check out the detailed analysis on Autocar, which discusses real‑world ownership experiences and market statistics.
