Caterham SP300R: 2012 Track-Focused Review And Specs

The Caterham SP300R stands as a pinnacle of engineering fusion between Caterham’s lightweight philosophy and Lola’s racing expertise. This isn’t just another roadster; it’s a purpose-built track machine designed to dominate circuits with its blistering acceleration, aerodynamic mastery, and featherweight construction.

Engineering a Lightweight Monster

At the heart of the SP300R lies a revolutionary chassis crafted by Lola, drawing directly from their Le Mans LMP-series race cars. This tubular aluminum honeycomb monocoque provides exceptional rigidity while keeping mass to a minimum—around 545kg or just over 1200lbs depending on specs. The result is a power-to-weight ratio exceeding 500hp per tonne, rivaling hypercars like the Bugatti Veyron but without the excess weight of luxuries such as windscreens or roofs.

Suspension duties fall to a fully adjustable Formula 3-derived system at the rear, featuring double wishbones, pushrod-actuated coilovers, and tunable anti-roll bars. Up front, a similar double-wishbone setup ensures precise handling. This configuration allows drivers to dial in settings for any track condition, from high-speed sweeps to tight technical sections.

Powertrain: Supercharged Fury

Propelling this lithe beast is a 2.0-liter Ford Duratec engine, supercharged by Rotrex to deliver 300bhp at 7500rpm and 213lb-ft of torque. Some configurations push to 305hp with a ‘push-to-pass’ overboost, peaking at 335hp. Mated to a Hewland FTR six-speed sequential gearbox with paddle shifts, gear changes are lightning-fast, especially under full throttle where torque flow remains uninterrupted.

Braking is handled by an AP Racing system, providing the stopping power needed for repeated high-speed laps. Exhaust options range from straight-through race setups to stainless steel for slightly tamer noise levels, essential for modern track days with sound restrictions.

Aerodynamic Supremacy on Slicks

The SP300R’s aerodynamic package, also penned by Lola, transforms it into a high-downforce weapon. A front splitter, adjustable carbon-fiber rear wing, diffuser, and flat underbody generate nearly 990lbs (half a ton) of downforce at 155mph, gluing slick tires to the tarmac. Shod on 13-inch Caterham Apollo alloys with Cooper F3 slicks, grip levels are otherworldly, enabling later braking and higher corner speeds.

Dimensions underscore its compact aggression: 132.3 inches long, 66.9 inches wide, 43.9 inches tall, with a 90.7-inch wheelbase. Track widths measure 57.9 inches front and 58.7 inches rear, optimizing stability. British Racing Green paint adds visual menace, intimidating rivals before a wheel turns.

Inside the Cockpit: Spartan and Secure

Entry demands contortionist skills—no doors, just a low-slung open cockpit. Once strapped in with a six-point harness under an FIA-approved roll cage, the minimalist interior reveals itself: three pedals, steering wheel, and essential gauges. A fire extinguisher and electrical cut-offs prioritize safety.

Steering feels heavy at low speeds, requiring muscle, but gains exquisite precision as pace builds. The sequential ‘box baulks in traffic but snaps gears flawlessly in anger. No carpets, leather, or windscreen means pure, wind-blasted focus—perfect for track purists.

Track Performance: Lap Record Aspirant

On circuit, the SP300R shines. Acceleration hurls you from 0-62mph in 2.8 seconds, with top speeds nearing 170mph. Downforce builds confidence; by lap two, drivers report 40mph higher speeds and later braking. It’s stable under braking, rotates eagerly in corners, and exits with explosive traction.

Safety features like the roll cage and harnesses allow pushing limits without fear. Noise is subdued thanks to the supercharger, complying with track regs. For single-make series or private sessions, it’s a class-winner, potentially future vintage racer material.

Who Is It For? Target Audience

• Track Day Enthusiasts: Those seeking more than modified road cars, craving race-level grip and speed.
• Racing Amateurs:

Ideal for club racing or single-make events with its adjustable setup.

• Collectors: Limited production ensures appreciation, especially post-2013 models.
• Adrenaline Junkies: 560hp/tonne demands skill but rewards mastery.

Not for daily drivers—it’s road-legal in theory but thrives on tarmac ovals.

Comparisons: SP300R vs. Rivals

Against Lotus Elise variants or Caterham’s own Seven lineup, the SP300R leaps ahead with superior aero and slicks. Power-to-weight crushes most, bar dedicated prototypes. Priced at £81k/$135k, it’s accessible for its league.

Ownership Realities and Costs

Base price hovered around £81,000, with options pushing higher. Maintenance suits track use: slicks wear fast, but Duratec reliability shines. Storage is simple due to size; transport via trailer for events. Resale holds strong for low-mileage examples.

Pros: Unmatched thrill, adjustability, pedigree. Cons: Accessibility challenges, noise, weather vulnerability.

Legacy and Evolution

Launched circa 2012 as Caterham’s first major new platform since 1994’s Caterham 21, it capitalized on F1 fame. Joint Lola venture elevated standards, influencing future models. Today, it beckons as a modern classic.
