Date Published: 5/15/08
2008 Jaguar XK Series Review
The 2008 Jaguar XKR Portfolio is a new top-end option package for this lineup of premium sporty cars. XK seats four, has V8 power, and comes as a 2-door hatchback coupe or a convertible with a power-folding soft top. All models have a 4.2-liter V8 engine. Base versions have 300 hp. The XKR is supercharged and has 420 hp. A 6-speed automatic is the sole transmission. Available safety features include ABS, traction control, antiskid system, and front side airbags that provide head and torso protection. All models have a navigation system, wireless cell phone link, and keyless entry and starting. XKRs have a sport suspension. The XKR Portfolio is an option package that includes unique trim and high-performance brakes.
Competition
Consumer Guide Automotive places each vehicle into one of 18 classes based on size, price, and market position. Offering more power and style than typical Sporty/Performance vehicles, Premium Sporty/Performance Cars usually cost much more and have more comfort and convenience equipment. Two-passenger convertibles and four-seat coupes rule the roost in this class.

Our Best Buys are the BMW Z4 and Chevrolet Corvette. Our Recommended picks are the Jaguar XK Series, Porsche Boxster, and Porsche Cayman.

New or significantly redesigned models include the Audi A5, Audi R8, and Audi TT.

2008 Jaguar XK Series Road Test
Consumer Guide® Road Test Ratings
Acceleration

Base coupe w/20-in wheels Base convertible XKR coupe XKR convertible Class Average
8 8 9 9 8.1

Base XKs are satisfyingly responsive at any speed. A convertible did 0-60 mph in 5.9 seconds in our test. XKRs are faster still: A coupe did 0-60 in 5.0 seconds. Both are aided by a quick-acting automatic transmission that doesn't hesitate to downshift for effortless highway passing. Standard steering wheel paddles are easy to use and provide even faster gear changes.
Fuel Economy

Base coupe w/20-in wheels Base convertible XKR coupe XKR convertible Class Average
5 5 4 4 4.2

In Consumer Guide testing, a base coupe averaged 20.6 mpg in mostly highway driving. Test convertible did 17.4 mpg with more city driving, 16.6 including gas-eating performance runs. Test XKR coupe averaged 16.3 mpg and 13.2 including performance runs. All XKs require premium-grade gas.
Ride Quality

Base coupe w/20-in wheels Base convertible XKR coupe XKR convertible Class Average
6 7 5 6 4.4

With standard 18-inch tires, the well-controlled base suspension delivers a firm but comfortable ride devoid of jolts and highway float. The base coupe with 20-inch tires and XKRs exhibit more impact harshness over sharp ridges and ruts. They're never punishing. Convertibles are free from undue body quivers over bumps.
Steering/Handling/Braking

Base coupe w/20-in wheels Base convertible XKR coupe XKR convertible Class Average
9 8 9 9 8.7

Base cars are confident and balanced in the grand-touring manner rather than razor sharp in the sports-car mold. There's little body lean even in fast turns. Here, 20-inch tires combine with the added rigidity of a coupe body style for crisper responses, added grip in turns. XKRs are sportier still. Steering is quick and precise, and the brakes are strong and sure. No opportunity to test an XKR Portfolio.
Quietness

Base coupe w/20-in wheels Base convertible XKR coupe XKR convertible Class Average
5 5 5 5 4.2

The engine growls nicely during acceleration, but cruises quietly. Coupes suffered some slight wind hiss from closed side windows. There's relatively little wind rush in the convertible with the top down, and top up, it's nearly as quiet as the coupe. Some tire noise is noticeable in both--especially with the 20-inchers--but it's never obtrusive.
Controls

Base coupe w/20-in wheels Base convertible XKR coupe XKR convertible Class Average
6 5 6 5 5.6

The controls and gauges are generally well placed. The navigation screen washes out in direct sunlight on the convertible. On all, the system absorbs most radio and climate functions, slowing and complicating their use; redundant audio controls help. A bigger issue is illegibility of the instrument panel screen in direct sunlight--a real problem in top-down driving.
Details

Base coupe w/20-in wheels Base convertible XKR coupe XKR convertible Class Average
7 7 7 7 6.9

Although a few plastic pieces disappoint, cabin materials are otherwise high quality and well-assembled. Standard wood or available aluminum trim each creates an inviting ambiance.
Room/Comfort/Driver Seating (front)

Base coupe w/20-in wheels Base convertible XKR coupe XKR convertible Class Average
7 7 7 7 5.8

Headroom and legroom are cramped for taller riders. XK's standard power tilt and telescopic steering column helps most find a comfortable driving position. Low build complicates entry and exit. Visibility is good except the rear roof pillars in both body styles interfere with over-the-shoulder vision.
Room/Comfort (rear)

Base coupe w/20-in wheels Base convertible XKR coupe XKR convertible Class Average
1 1 1 1 .7

A token gesture. The seat is best used for parcels. Entry and exit requires contortions, even for short passengers.
Cargo Room

Base coupe w/20-in wheels Base convertible XKR coupe XKR convertible Class Average
3 3 3 3 2.6

Demands careful packing. The coupe's hatchback design eases access to the coupe's luggage area, which has slightly greater overall volume than the convertible's trunk. Neither body style has folding rear seatbacks, however. Ordering the optional run-flat tires omits a spare tire and frees up additional cargo space beneath the floor. The cabin lacks small-item storage.
Value within Class

Base coupe w/20-in wheels Base convertible XKR coupe XKR convertible Class Average
7 7 6 6 5.3

An enticing blend of grown-up performance and sporty luxury makes XK a Recommended pick. XKR adds even more performance and sharper handling. Rivals such as the Mercedes-Benz SL and Cadillac XLR offer the security of a power metal retractable roof, but the XK convertible's fabric top is well insulated and consumes less cargo room when folded. Price-wise, Jaguar's base XKs slot attractively between comparable versions of the BMW 650i and the Mercedes SL550, while XKRs are significantly cheaper than an M6 or SL63.

Pricing Key: Retail prices listed with each report are set by the vehicle's manufacturer. These figures appear on each car's federally mandated window sticker. Most price lists also include dealer-invoice prices. Dealer-invoice prices are what the dealer pays the manufacturer for the car and its factory-installed options. The destination charge is not included in the suggested-retail or dealer-invoice price and must be added to the cost of the vehicle. Car companies change prices frequently throughout the year. If the prices published do not match those on the vehicle's window sticker, the manufacturer has probably altered the price recently.
NA = price note available, NC = no charge.

NHTSA Crash-Test Results
Test Jaguar XK Series 2-door hatchback Jaguar XK Series 2-door convertible
The National Highway Traffic Safety Administration (NHTSA) tests a vehicle's worthiness in front- and side-impact collisions and rates its resistance to rollovers. Front-impact crash-test numbers indicate the chance of serious injury: 5 = 10% or less; 4 = 10-20%; 3 = 20-35%; 2 = 35-45%; 1 = More than 45%. Side-impact crash-test numbers indicate: 5 = 5% or less; 4 = 6-10%; 3 = 11-20%; 2 = 21-25%; 1 = More than 26%. Rollover resistance numbers indicate the chance for rollover when the vehicle leaves the roadway: 5 = Less than 10%; 4 = 10-20%; 3 = 20-30%; 2 = 30-40%; 1 = More than 40%.
