1968 Jaguar XK-E (Series 1.5)
The 1968 Jaguar XK-E, commonly referred to as the Series 1.5, represents a significant evolutionary step for one of the most iconic sports cars of the 20th century. Building upon the foundational brilliance of the original E-Type, this iteration introduced a blend of improved practicality, enhanced comfort, and subtle mechanical refinements, all while retaining the breathtaking beauty and exhilarating performance that defined its predecessor.
Historical Context and Evolution:
The E-Type, launched in 1961, was a revolutionary automobile, praised for its stunning aerodynamic design, innovative engineering, and accessible performance. By 1968, Jaguar sought to address some of the criticisms leveled against the earlier Series 1 models, particularly regarding creature comforts and usability. The Series 1.5 was a transitional phase, bridging the gap between the purist Series 1 and the more production-oriented Series 2. It retained many of the Series 1's desirable visual cues while incorporating key updates to meet evolving safety and emissions regulations and to appeal to a broader customer base.
Design and Styling:
The Series 1.5 E-Type is instantly recognizable for its elegant and flowing lines, a direct lineage from the original Malcolm Sayer design. Key visual changes from the Series 1 include:
- Open Headlights with Glass Covers: This is the most distinguishing feature of the Series 1.5. The faired-over headlights of the Series 1 were replaced with exposed headlamps, but crucially, these were covered by clear glass fairings, maintaining a degree of aerodynamic continuity and a distinct visual signature.
- Revised Grille: The grille received a more substantial, open design compared to the Series 1, often featuring a deeper, more prominent central opening, which also contributed to improved cooling.
- Twin Electric Screen Wipers: Moving away from the single, centrally mounted wiper of the Series 1, the Series 1.5 adopted a more conventional dual-wiper setup for improved visibility.
- Side Marker Lights: In compliance with new US safety regulations, small amber side marker lights were integrated into the front fenders and red units in the rear.
- Chrome Trim: A subtle increase in chrome detailing was often observed, adding a touch more flourish to the car's already opulent appearance.
The interior, while still driver-focused, saw improvements:
- Improved Dashboard Layout: The dashboard retained its classic aesthetic but often featured a revised layout with updated switchgear and instrumentation for better ergonomics.
- Comfortable Seating: Seats were often updated for greater comfort and support, making longer journeys more enjoyable.
- Optional Air Conditioning: For the first time, air conditioning became a factory-available option on some Series 1.5 models, a significant step in making the E-Type a more viable grand tourer.
Mechanical Specifications and Performance:
The 1968 Series 1.5 E-Type primarily offered the following:
- Engine: The mainstay was the legendary 4.2-liter DOHC inline-six engine. This potent powerplant, known for its smooth delivery and impressive torque, produced approximately 265 horsepower.
- Transmission: Buyers could choose between a 4-speed manual gearbox (often with synchromesh) or the increasingly popular 3-speed Borg-Warner automatic transmission. The manual offered a more engaging driving experience, while the automatic appealed to those seeking greater ease of use.
- Chassis and Suspension: The E-Type's renowned independent suspension, utilizing trailing links at the rear and wishbones at the front, was largely carried over. This sophisticated setup contributed to the car's exceptional handling characteristics, offering a superb balance of ride comfort and cornering prowess.
- Brakes: Four-wheel disc brakes, a groundbreaking feature for a production car at its launch, remained a key component of the E-Type's performance, providing strong and reliable stopping power.
- Body Styles: The Series 1.5 was available in its iconic forms:
- Coupe (FHC - Fixed Head Coupe): A practical 2-seater sports coupe.
- Convertible (OTS - Open Two Seater): The quintessential open-top sports car experience.
- 2+2 Coupe: A longer wheelbase version offering a slightly more practical rear seating area.
Driving Experience:
The 1968 E-Type continued to deliver a driving experience that was both thrilling and sophisticated. The powerful inline-six provided effortless acceleration and a delightful soundtrack. The precise steering and well-balanced chassis allowed for confident cornering, making it a joy to drive on winding roads. While the glass-covered headlights contributed to a slight reduction in ultimate aerodynamic efficiency compared to the Series 1, they also offered a distinct visual appeal and a compromise that many found acceptable. The improved comfort and optional air conditioning made it a more viable option for everyday use and longer journeys than its predecessors.
Legacy and Significance:
The 1968 Jaguar XK-E (Series 1.5) holds a significant place in the E-Type's history. It represents a period of refinement and adaptation, where Jaguar sought to maintain the magic of its groundbreaking sports car while making it more practical and compliant with modern standards. These cars are highly sought after by collectors and enthusiasts alike for their enduring beauty, engaging performance, and the added usability that distinguishes them from earlier Series 1 models. They embody the spirit of British motoring at its finest, a perfect fusion of style, engineering, and pure driving pleasure.
