Jaguar Lightweight E-Type Revival Review: Inside The Missing Six

The Jaguar Lightweight E-Type stands as a pinnacle of automotive engineering, originally conceived in the 1960s as a race-bred evolution of the iconic E-Type. In 2015, Jaguar Heritage brought this legend back to life through a continuation series known as the ‘Missing Six,’ completing the 18 chassis originally planned but only partially realized. These cars combine period authenticity with contemporary craftsmanship, weighing around 960kg thanks to extensive aluminum use, and delivering over 300 horsepower from a refined straight-six engine.

The Origins of a Racing Legend

Developed in 1963, the Lightweight E-Type emerged from Jaguar’s ambition to dominate sports car racing. Only 12 of the intended 18 cars were produced at the time, leaving six ‘missing’ until Jaguar’s 2015 revival project. The originals featured monocoque aluminum body panels, including doors, hood, and trunk lid, slashing weight by approximately 114kg compared to standard steel-bodied E-Types. This reduction transformed the car into a competitive racer, capable of challenging contemporaries on circuits worldwide.

Jaguar’s state-of-the-art scanning technology played a crucial role in the revival. Engineers digitally mapped original bodyshells to ensure dimensional accuracy, preserving the design vision of Sir William Lyons and Malcolm Sayer. The result is a vehicle that honors its heritage while meeting modern FIA historic racing standards.

Engineering Marvels Under the Skin

At the heart of the Lightweight E-Type lies the XK straight-six engine, enlarged to 3.8 liters with an aluminum block and cylinder head. Early versions used Lucas mechanical fuel injection for sharp response, while others feature Weber carburetors. Output hovers around 340bhp, with torque peaking at 280 lb/ft at 4,500 rpm, propelling the featherweight chassis with ferocious acceleration estimated at 0-60mph in 4.5 seconds.

The chassis retains the classic monocoque structure but with lightweight aluminum panels throughout. Steering is unassisted rack-and-pinion, paired with a wooden-rimmed wheel, demanding driver input but rewarding with precise feedback. Brakes employ Girling disc setups front and rear, optimized for the era’s racing demands without modern aids like ABS.

Design and Aesthetics: Timeless Elegance

The Lightweight E-Type’s silhouette remains Enzo Ferrari’s famed ‘most beautiful car ever made,’ but stripped for performance. Gone are carpets, stereo, and luxuries; the interior is spartan with bare aluminum floors and minimal gauges. Its narrow 66.9-inch width and low 46.5-inch height create a purposeful stance, enhanced by wider racing wheels and subtle aerodynamic tweaks like a small rear spoiler on some examples.

Painted in British Racing Green or silver, these cars exude rarity. Jaguar produced the continuation series with meticulous detail, from hand-beaten panels to correct badging, ensuring each feels like a 1960s original. Director of Design Ian Callum emphasized fidelity to the Lyons-Sayer blueprint, making the revival as visually stunning as its forebears.

Performance on Road and Track

• Engine Character: The 3.8L six awakens with a guttural roar, idling roughly before surging above 3,000 rpm. Throttle response is immediate, especially with Weber carbs, pulling eagerly to 6,000 rpm.
• Handling Dynamics: Light weight and low center of gravity yield neutral balance. The unassisted steering communicates every surface change, while the short wheelbase aids agility on twisty roads or circuits like Navarra.
• Transmission Feel: The 4-speed manual shifts sweetly with light action, though the long-travel clutch demands practice. Rev-matching is manual, adding to the raw engagement.
• Braking and Grip: Disc brakes haul the car down effectively, supported by wide tires for cornering prowess. It’s surprisingly approachable despite its race pedigree.

Drivers note its dual personality: tractable on public roads, yet ferocious when pushed. One tester described it as a ‘pussycat’ in traffic but a beast on track, with binary throttle inputs amplifying the drama.

Behind the Revival: Jaguar Heritage’s Mission

Jaguar’s Heritage division spearheaded the 2015 project to finish the Missing Six, using original drawings and surviving prototypes. Each car underwent rigorous testing for FIA homologation, allowing competition in historic events. Valued deep into seven figures—up to £1.2 million—these are among the most expensive Jaguars ever, blending collectibility with drivability.

The process involved recreating period parts unavailable for decades, from fuel injection systems to lightweight cylinder heads. Modern tools ensured tolerances exceeded originals, yet the ethos remained analog—no electronics dilute the experience.

Ownership Considerations for Enthusiasts

Prospective owners face high acquisition costs, but maintenance benefits from Jaguar’s support. Parts are available through Heritage, though specialist knowledge is key for the fuel-injected variants. Fuel economy is modest at around 15-20 mpg, with a 14-gallon tank suiting spirited drives over long hauls.

Insurance demands proof of secure storage and limited road use. Track days in historic series offer the ultimate reward, where the Lightweight shines against Ferraris and Porsches.

Comparing Lightweight to Standard E-Type

The Lightweight’s advantages in power-to-weight ratio make it markedly quicker and more agile.

Modern Relevance and Collectibility

In 2026, the Lightweight E-Type transcends mere nostalgia. Its engineering principles—inherent balance, naturally aspirated power—inspire contemporary designs. Auctions see prices escalate, affirming its status as a blue-chip investment. For purists, it offers unfiltered driving joy unavailable in sanitized supercars.

Frequently Asked Questions (FAQs)

What makes the Lightweight E-Type special?

Its ultra-light aluminum construction, high-output engine, and limited production (only 18 total) set it apart as a racing icon reborn with modern accuracy.

Is the 2015 revival road-legal?

Yes, though primarily for track use; some are registered for road, but check local regulations.

How does it compare to modern sports cars?

Despite 340bhp, its 2,300-lb weight delivers explosive performance akin to lightweight exotics, minus aids.

Can I race a continuation Lightweight?

FIA-approved for historic categories, yes—perfect for events like Goodwood Revival.

What’s the top speed?

Over 170 mph, limited by gearing and aerodynamics.
