| − | Clearly relying on the styling the Mercedes-Benz SLK, the brand new Cadillac XLR shares the squared off look of other recent Cadillacs. It does not look bad in any way, even though the headlamps look like they've been squeezed to fit alongside the wide grille. The performance puts it in the supercar class.

| − | Top speed is fixed to 155 mph, therefore it may get to 60 mph in approximately 5.7 seconds - that's slightly quicker than the Jaguar XK, because of the larger engine. Other competitors include the Mercedes-Benz SL and Porsche 911.

| − | Looks could be deceiving. The automobile is wide and low, and appearance big. In fact, it is quite compact, just 177.5 inches long and 72.2 " wide. The automobile looks very good, particularly from your side. And you also get a very practical SLK-lookalike opening roof. I assume most convertibles will probably be 'metal' convertibles soon, as well as the rag tops will disappear - maybe not on all supercars. To save weight, the rooftop from the XLR is aluminum and magnesium.

| − | Good power output

| − | Also, the XLR has quite a lot of power: 326 bhp at 6,500 rpm and 312 lb ft (423 Nm)at 4,400 rpm from GM's Northstar 4.6 liter V-8, which may work a bit harder - 350-360 bhp, which will not difficult to get from this engine, will make things more interesting.

| − | | + | |
| − | As it is, it's enough to own car a serious shove, and because the Northstar has an aluminum block and head with dohc and four valves per cylinder, it revs well. Variable valve timing improves the spread of power, too.

| − | The engine is coupled to some rear mounted five-speed automatic transmission - 5 speeds place it at a disadvantage up against the European supercars which mostly have six-speed automatics, but it is designed to give sporty shifts. As the box is rear-mounted and also the engine is fairly well back, front/rear weight distribution is 50/50.

| − | New frame concept
| + | |
| − | | + | |
| − | Based on GM's new platform for sporty cars shared with the Corvette, the XLR features a fairly light frame of hydro-formed steel tubes. Hydroforming changes the design quite dramatically, putting in bends, changing the section to some rectangle and so forth, making a lightweight frame. The passenger compartment is aluminum, and the body panels are composite plastics. This can be a structure that can compete with many a supercar.

| − | | + | |
| − | It is a fairly light structure, and despite the high level of equipment, the car weighs a proper 3,643 lb (1,654 kg) that is just 130 lb more than the new lightweight Jaguar XK, as well as a great deal a lot more than the Corvette that features a lower spec but bigger engine.

| − | Double wishbone suspension
| + | |
| − | | + | |
| − | Suspension may be the familiar Corvette style of double wishbones front and rear with transverse leaf springs. It makes sense a straightforward, lightweight system that offers more roll stiffness - capacity roll - than coil springs. Also, the spring minute rates are progressive, so that it irons out big bumps inside the road almost as easily as little ones. Additionally there is a front anti-roll bar.
| + | |
| − | | + | |
| − | To save lots of weight, the double wishbones back and front are aluminum; of course, the composite leaf springs are light, too. Leaf springs with this type - just one single leaf - are in reality quite advanced technology as they don't locate the wheels, and involve some clever manufacturing techniques.

| − | | + | |
| − | The dampers will be the new continuously variable electro-magnetic type, and the steering is speed sensitive, so you have more assistance at low speed.
| + | |
| − | | + | |
| − | As this is a Cadillac, it arrives with a higher specification. For Europe, navigation, and heated/cooled seats are standard as are adaptive speed control plus a head-up display. The interior, having its wood, leather and aluminum trim is very pleasant

| − | Integrated the same plant and also to exactly the same concept as the Corvette, the Cadillac XLR is better thought of a softened up Corvette meant for those that desire a better ride.
| + | |
| − | | + | |
| − | Visibility is good thanks to slim pillars within the opening roof, and also the almost flat hood. Just like the Corvette both the instruments and driving position are great. There is also a head-up display which shows merely the speed and which gear you're in, and you also don't appear able to switch off. Pity. I didnrrrt believe it is useful.

| − | | + | |
| − | The steering is not bad whatsoever, and also the XLR turns in well, as you'd expect your weight distribution, however when you start pressing, you commence to feel a little understeer to arrive, that isn't bad for the market this can be aimed at - more the luxury sports vehicle that the hard charging supercar driver. Nevertheless the car does not corner as quickly as you might with more neutral steering.

| − | | + | |
| − | The automated is great. In D, the performance isn't bad at all, and the kick-down is very aggressive. Additionally there is a manual mode. Push the lever across to the left, then nudge it forward for up, and back for down. This works extremely well, and also is really a manual. I mean, many of these actually shift up once you hit peak revs. Not this; it really allows you to stay there till you're ready.
