The Big Blue Cat: Our customer Dave gives an overview on his KWE upgraded XJS

My other half is Sarah, and the Big Blue Cat in the heading relates to our 1990 XJ-S 5.3 litre convertible, in Solent Blue with Saville Grey interior. It’s actually Sarah’s baby, bought for her after many, many patient years of waiting.

 

Jags are in her family, with her brother owning an E-type and various uncles having Mark Xs and Mark 2s throughout life, but the XJ-S was always her personal desire. She’s had to put up for many years with my love for Land Rovers of all shapes and sizes, from Series 1, 2 and 3 through to Discovery 2s and 4s, Range Rovers Series 1s and P38s plus off-roaders and finally our White Witch, a white Discovery Sport 2.2 litre with the registration W1 CHH. Sarah has dabbled with imports, via a Chevy Astro 4.0 day van, a lifted and overboard 3.2 XXS Toyota surf, a Mitsubishi Delica 3.0 litre petrol and her latest, which we still have, a 260bhp Nissan Elgrand. All these came after turning down the chance to buy her first XJ-S convertible in wine metallic for £4000 many years ago. In those days though there was no place for the two kids and the two dogs.

“We have an XJ-S Plus, all the car anyone could want from a Jaguar and then some.”

So after many years of waiting, we bought the cat in late February this year, in nice condition as it was, but then decided to hand it over it to Chris Knowles at KWE so he could, as he put it, “Make it the car what it SHOULD have been in the first place”.

 

KWE Suspension Upgrades

For the first of their upgrades we plumped for their S1 suspension upgrade, which includes a suspension, steering and brake upgrade, note they say upgrade, not replacement as this makes the car better than when it was new in their opinion.

This included the complete stripping of the suspension, brakes and steering unit from the car, then each individual section stripped down, all those old BL bushes, shocks, joints, dampers, discs, springs and joints as well, basically thrown away. Each major section is then shot blasted and powder coated in zinc and then finished in black or another colour should you ask for it, and all wearing, perishable and moving parts renewed with OE or if they are not available, KWE manufactured parts. It’s then all put back together by a single person, only one mechanic to a car, and refitted with a full geometry steering set up done.

 

 

The suspension is then adjusted to how you like it, (Sarah went for sporty!) and road tested until they are sure all is perfect.

 

Engine & Cooling System

The next decision for us was what to do with the engine, so we opted for their V12 30,000 mile perishable service, with full cooling system renewal, in Chris’s words “The cooling system renewal is so important for V12s because cooling was marginal when new, let alone with clogged old pipes and failing pumps”. There were other options, but as the car had only done 56,000 miles and only 6,000 since 2007 it was thought the engine wouldn’t warrant any more.

What is included in their V12 30,000 mile perishable service, is anything perishable being removed and in place a new radiator, hoses, drive belts, new plug leads and plugs, thermostats, water pump, new electric fan and fan couplings. This is followed by a full chemical flush of the engine coolant system and all oilways, followed by a full 30,000 mile service to body and engine, with any engine tuning needed to get it to the top notch performance you’d expect. Also the gearbox and differential oils are changed and in our case, gearbox mounting bushes changed, see the picture for what came out and what went back!

The Interior & Exterior

Next the cabin, and it wasn’t so difficult to sort this one, as the carpets, leather and wood were already in very good condition and in the way KWE do things, “Not really something we need to touch,” Chris advised us. Still it just needed something to finish it off and then with the options Chris suggested we saw what it was. We then dumped that dodgy 1990 black plastic steering wheel in favour of a gorgeous Motalita Mk5 flat spoke holed steering wheel with polished centre horn push and a change to the T-bar on the gear selector from black plastic to wood matching the dash and surrounds. It finished it to a tee. As a finale KWE gave the paint a machine polish and wax to the interior valet including the seats getting a proper clean and a leather feed, making them just so.

 

The Finishing Touch

The dashboard instruments had all the illumination of a Victorian candle in a hurricane, so we went for a full interior lighting and instrument panel LED upgrade, and just to make life difficult for KWE, we requested that they do an experimental LED upgrade (never done before on an XJS) of all the control switches on the dash and centre console. This included the heater controls as well. They came through on that task with flying colours.

We got the car back in June, after a much anticipated wait and well !!!!!, was Chris right, it corners on rails, glides along on its new running gear like it is on air. You can see at night, like a modern car. The engine purrs and even after a half hour sit in traffic in recent very hot weather it sat rock solid normal in the temp zone. We’re also averaging 18mpg around town and on a recent long run 23.5mpg.

 

Was it worth the cost? Well, we’ve spent quite a bit more than the value of the car but what a car it is now!

Worth it ? Oh yes without a doubt, we have an XJ-S Plus, all the car anyone could want from a Jaguar and then some.

With thanks to Dave and Sarah Ash.

Changes to our Payment Terms

As of 13th January 2018 a law has come into force requiring companies who accept credit card payments to absorb the charge that the credit companies levy on such transactions. This levy is typically between 2.5% and 3% (more for American Express). With high value transactions such as ours, this levy is very significant and can be many hundreds of pounds which previously was passed on to the customer since credit cards are a convenience for the client, not the supplier.

KWE now regrets that it can no longer as of 23rd January 2018 accept credit cards as a means of payment. We are happy to accept debit cards, cheques and internet bank transfers.

This change has been made in our Terms of Business

We apologise for the inconvenience this may cause.

American Jaguar XJS buyers choose British restorations 🇺🇸

Well, why not get the world’s largest and most experienced Jaguar XJS restorations specialist make that dream a reality.

American Jaguar XJS Restorations

The Jaguar XJ-S is one of the most stylish sports touring cars in the world. It is entirely happy to be driven daily, whilst in great comfort and class. Owning an XJ-S marks you out as an individualist with impeccable taste. The feeling of grandeur you get while sitting in the cockpit wrapped in fine leather, wood and wool. Driving one makes you feel like you’re the king of the road, especially with KWE’s perfected steering, brakes and suspension set-up, ensuring you stay flat and low on the tarmac, while taking the sharpest of corners effortlessly. The all-aluminium V12 is the smoothest around – and one of the most reliable when properly restored and maintained.

“The suspension changes and power enhancement package have completely transformed this car. The difference between the standard set up and your upgrade is quite simply astonishing.”

KWE Jaguar restoration at the NEC classic motor show

KWE has been restoring Jaguars for 15 years!

Knowles-Wilkins Engineering (KWE) Ltd has reached its 15th Anniversary. From being very much new kids on the block back on 2002, we have become well known at home and abroad for our Jaguar XJS restoration and modernisation work. Owners Chris and Theresa Knowles started the company from their home and, perhaps surprisingly, took three major orders in the first two months, appeared on Top Gear twice and turned over around £100,000 before moving the business (and home) to Newbury, Berkshire in 2004. Since then we have restored over 300 cars, most with our admired full suspension/brakes/steering upgrade package.

We currently employ 10 staff and occupy three very busy premises on Greenham Business Park, and are currently recruiting. We would like to thank all of our past and present customers for their continued support and love for the Jaguar.

We have expanded our works to include XK, all XJ saloons, E Types and Aston Martin DB7s. We are continuing to develop, improve and revitalise these astounding classic and future classic cars.

KWE are now offering servicing for Jaguar X300, X308, X-Type, S-Type, XK8/R.

Happy owners! Chris & Theresa Knowles on KWE’s 15th Anniversary.

Fully Electric Jaguar E-Type Zero a Truly Modern Classic

Jaguar Land Rover Classic electrifies the past with an inventive Jaguar E-type sports car featuring fully electric powertrain

 

 

  • Acclaimed by Enzo Ferrari as “the most beautiful car in the world”, the Jaguar E-type now combines breathtaking beauty with zero emissions for the first time
  • E-type Zero is based on 1968 Series 1.5 Jaguar E-type Roadster, and features a cutting-edge electric powertrain enabling 0-62mph in just 5.5 seconds
  • Engineered by Jaguar Land Rover Classic at company’s new ‘Classic Works’ in Warwickshire, UK
  • E-type Zero makes world debut during Jaguar Land Rover Tech Fest at Central Saint Martins, University of the Arts London from 8-10 September
  • E-Type Zero will sit alongside the all-electric Jaguar I-PACE at Tech Fest, which goes on sale in 2018

“E-type Zero combines the renowned E-type dynamic experience with enhanced performance through electrification. This unique combination creates a breathtaking driving sensation.

 

“Our aim with E-type Zero is to future-proof classic car ownership. We’re looking forward to the reaction of our clients as we investigate bringing this concept to market.”

Tim Hannig, Director, Jaguar Land Rover Classic

The Jaguar E-type Zero not only drives and looks like an E-type, it also offers outstanding performance. It’s quicker than an original E-type: 0-100km/h (62mph) takes only 5.5sec, about one second quicker than a Series 1 E-type.

“In order to seamlessly combine the new electric powertrain of E-type Zero with the dynamic set-up of the original E-type specification, we have limited the vehicle’s power output. We believe this provides the optimum driving experience.”

Tim Hannig, Director, Jaguar Land Rover Classic

The E-type Zero vehicle, displayed at Tech Fest, is a restored Series 1.5 Roadster. It’s totally original in specification, apart from its 21st century state-of-the-art powertrain and modified instrumentation and fascia – although these are also inspired by the original E-type. LED headlights are also used to achieve energy efficiency. Again, they adopt the styling theme of the original Series 1 E-type.

 

 

Bespoke electric powertrain

An electric powertrain developing 220kW has been specially designed for the E-type Zero. Its lithium-ion battery pack has the same dimensions, and similar weight, to the XK six-cylinder engine used in the original E-type. The experts responsible for developing the electric powertrain have ensured it will be placed in precisely the same location as the XK engine. The electric motor (and reduction gear) lies just behind the battery pack, in the same location as the E-type’s gearbox. A new propshaft sends power to a carry-over differential and final drive. Total weight is 46kg lower than the original E-type.

 

 

Using an electric powertrain with similar weight and dimensions to the outgoing petrol engine and transmission means the car’s structure, including suspension and brakes, has not changed, simplifying the conversion and homologation. It drives, handles, rides and brakes like an original E-type. Front-rear weight distribution is unchanged.

 

“We have integrated the new electric powertrain into the existing E-type structure, which means a conventional engine could be reinstalled at any point. We think this is essential as it ensures a period Jaguar remains authentic to its DNA.”

Tim Hannig

 

The XK six-cylinder engine was made from 1949 until 1992, and was fitted to nearly all iconic Jaguar models of that period, including the E-type, XK120, Mk2 and XJ6. The new electric powertrain could be used in any of these vehicles.

“We could use this technology to transform any classic XK-engine Jaguar.”

Tim Hannig

‘The most beautiful car ever made’

The E-type, launched in 1961, has regularly been voted the best-looking car of all time. Even Enzo Ferrari called it “the most beautiful car ever made”.

 

 

E-type Zero’s unique electric powertrain was developed by an electric powertrain specialist in conjunction with Jaguar Land Rover engineers and to a specific brief from Jaguar Land Rover Classic. It uses some technology and components borrowed from the upcoming I-PACE, Jaguar Land Rover’s first production all-electric vehicle.

 

 

The E-type Zero has a ‘real world’ range of 270km (about 170 miles), helped by the low weight and good aerodynamics. It uses a 40kWh battery, which can be recharged from home overnight (typically in six to seven hours, depending on power source).

 

 

This is an extremely interesting development from Jaguar Classics, one that we at KWE like very much, having put thought into a similar project for the XJS… now that would be an exciting prospect, a fully electric Jaguar XJS. It would make these beautiful, comfortable classics timeless and clean.

KWE works their magic on an E-Type with a 6 litre V12 Engine

Yesterday, KWE had a visit from a customer who brought his beautifully restored Series 3 Jaguar E type for us to look over. It recently had a brand new late 6 litre fuel injected engine, with AJ6 Engineering power and torque enhancements installed by another company.

 

KWE V12 ETYPE

 

Unfortunately, the engine was not running smoothly at all, suffering from throttle lag among other things that were affecting its performance and efficiency. Luckily for him, AJ6 Engineering pointed him in the direction of KWE, who was able to rectify the issues with their specialist knowledge of the V12 engine.

“It has transformed the feel of the engine making it smoother and more responsive.”

 

V12 ETYPE

 

After diagnosing the problem, KWE was able to fix the throttle lag issue within a couple of hours, resulting in a much smoother and responsive drive, while also significantly reducing the emissions at the same time, with some smart adjustments to the ECU.

“I also noticed the fuel gauge did not go down quite so rapidly on my return journey!”

 

V12 ETYPE

 

When the E-type came in to the KWE workshop, the emissions test was reading 7.9% CO, just before leaving it was down to 0.3% CO, which is an incredible reading for a car running a 6 litre V12 engine!

 

V12 ETYPE

 

We asked the proud owner to give us a few words on his marvellous machine:

“My V12 Roadster is the 4th E-type I have owned, and by far the best (and that includes a restored and upgraded early Series 1 3.8). When this Series 3 was restored it was re-built with a new factory fresh fuel injected 6.0 litre V12 which included upgrades from Aj6 Engineering in the form of their Torque Plus kit and larger throttle bodies to accompany their TT exhaust system. In all, giving a significant increase in power and torque. Not to mention a V12 that sounds wonderful! With all the suspension upgraded to include adjustable dampers and neoprene bushes, upgraded XJS brakes, an XJS 2.88 LSD diff it makes this 1974 car feel appropriately up-dated in every possible department. Just a magnificent car to drive and to own.“

Another happy Jaguar owner driving off in his much smoother running V12 E-type.

If you are experiencing any issues with your V12 engine, arrange a booking with KWE.
