Sony Xperia Z4 (Z3+) price:

Description of the smartphone Xperia Z4

Exactly one year ago, the Japanese company Sony introduced its new flagship under the non-standard name Xperia Z3 +, although for the international market, this model was consecrated as Xperia Z4. In order not to be confused with these names, in our description we will call the smartphone in the international version.

One of the main features of the smartphone is the main camera. It has a built-in 20 megapixel sensor, a 2.0 aperture lens and a 1.12 µm pixel size on the matrix. The device can shoot video in 4K resolution at 30 frames per second. The front camera for video calls or selfies is 5.1 megapixels.

As for the screen, here the Japanese manufacturer installed an IPS display of its own production with proprietary technologies such as Triluminos display and X-Reality Engine. It has a resolution of 1080x1920 pixels and a diagonal of 5.2 inches. It is worth noting that the screen is protected by tempered glass.

Internal stuffing Xperia Z4 is an eight-core Snapdragon 810 processor, where I work two pairs of 4 cores, 32 GB of internal memory for storing files and 3 GB of RAM. Also, this gadget has the ability to install additional memory in the form of a microSD card.

The company positions the smartphone as a flagship model. Accordingly, the price of this gadget will not be very low. All stores where you can buy this model you will find under the main picture.

Video review Sony Xperia Z4 (Z3+):

The BMW Z4 Roadster is an open, two-seater successor to the Z3 roadster. Compared to its predecessor, the Z4 has grown a bit in all directions. Like its predecessor, the BMW Z4 is built in the US at the Spartanburg plant. The roadster went on sale in the United States in October 2002, and did not appear in Europe until March 2003.

The BMW Z4 is a classic roadster with a sporty edge. Shark features appear in the design of the car: toothy "jaws" of a false radiator grille, a heavy gaze of headlights, a faceted long "muzzle". Convex and concave surfaces create a magnificent play of light and shadow. The BMW Z4 has a waist. It is formed by "hollow" doors, behind which the body seems to expand. The notch on the door is bounded from above by a clear edge of the waist line, and from below by an equally sharply defined “stiffening rib” of a high threshold. The slash completes the picture, boldly drawn from the bottom up from the front wheel to the windshield frame. And in the middle of this sloping edge is a white and blue BMW emblem, under which an orange “turn signal” repeater is hidden. The characteristic BMW radiator grille, surrounded by high-gloss chrome and optional dual xenon headlights with integrated fog lights, gives the Z4 an elegant and assertive look. AT standard equipment The Z4 2.5i offers an elegant, mechanically operated fabric tarpaulin. The motorized tarpaulin (optional on the 2.5i and standard on the 3.0i) opens in just 10 seconds.

The main "forming surface" of the interior is the "curved-concave" front panel. All the information you need is at your fingertips thanks to the chronograph-style instruments. An advanced navigation system with a 16x9 display - a non-glare TFT monitor (option) - is pulled out of the instrument panel by pressing a special button. The steering wheel is small, fine, with a leather rim and incredibly stylish metallized spokes. The design in the BMW Z4 is at its best, every detail has been worked out - whether it is protective arches behind the seats, a handbrake handle or door panels, “crossed out” with special “twisted” handles. The interior of the sports version with a “metal” finish is especially good. "Sport" seats for driver and passenger are standard on the Z4. In the Comfort version, only natural wood inserts create some warmth, replacing the silvery plastic panels under aluminum. Otherwise, everything is extremely restrained, technologically advanced and “sterile”. Not a single superfluous, pretentious detail, but each of the available ones is perfect in its completeness and functionality.

The advantage of the new body is a relatively large trunk (up to 260 liters) with a convertible awning compartment, which is quite enough to carry two large bags. The fabric tarpaulin folds in a Z-shape and is equipped with a heated rear window.

Additional options include a Hi-Fi audio system with a bass booster using Carver technology, as well as a special phone. The standard equipment of the new Z4 includes a sports-style leather steering wheel, a roll-over protection system and tires that allow you to drive yourself to a tire changer in case of a puncture.

High-octane blend of impeccable quality and the most modern technologies is the basis of the six-cylinder engines of the BMW Z4, made of a special lightweight alloy. Thanks to the combination of the unique Double Vanos system, which allows you to adjust the valve operation in an optimal way, a special air intake module and BMW four-valve technology, it was possible to achieve the highest torque and lightning-fast response. When the Sport mode is activated, the optional Driving Dynamic Control takes the engine power to an even higher level. The Z4 models are equipped with the 3.0i (170 kW / 231 hp / top speed 250 km/h) and Z4 2.5i (141 kW / 192 hp / 235 km/h) engines. The Z4 3.0i is equipped with a six-speed manual transmission and a five-speed for the Z4 2.5i, or a five-speed automatic transmission (installed as an option).

Thanks to its wide track, low center of gravity, optimal 50:50 axle weight distribution and precise steering (Electric Power Steering), the BMW Z4 delivers excellent agility and handling. In addition, durable high-performance brakes and Dynamic Stability Control (DSC III) with traction control enable maximum driving safety in all driving situations.

For the first time in the history of BMW cars, the Z4 replaces the familiar power steering with electric power steering. This scheme is much simpler. The electric power steering consumes energy only when the steering wheel is turned, and it is very easy to control its operation in accordance with the speed or level of lateral accelerations. But if BMW engineers and ZF, which traditionally supplies steering mechanisms to Bavarians, have decades of experience in adjusting the reactive action of hydraulic boosters, then with electric motors everything will have to be comprehended anew. The Z4 Sport version is extremely responsive to the slightest turns of the steering wheel. And pressing the "sport" button on the console to the left of the gear lever changes not only the characteristics of the "electronic" gas pedal, but also the algorithm of the electric power steering. In "sport" it is better to ride, but not by much. The effort on the steering wheel is higher, but there is still no “transparency”. Reactions are instantaneous, but not accurate - you have to adjust the trajectory in high-speed turns with fast impulse movements. But at the same time, when cornering, the BMW Z4 is no slower than the Speedster. Firstly, the power unit here fully justifies this definition: it is really power. Traction "on the bottoms" is powerful, and after 3000 rpm, pressing the gas pedal instantly causes a jet push in any gear! Chassis here, whatever you say, excellent. Tires cling to the pavement with a stranglehold, suspension geometry allows the roadster to easily follow the wheel and willingly dive into high-speed turns. Gradually, you get used to the reactions of the car, and the only thing that annoys you is the need to rest your knee on the door handle in the left turn.

The brakes are great. The force on the pedals and its stroke are chosen so that they make it easy to brake just on the verge of blocking - that is, you squeeze the maximum deceleration out of the car without turning on the ABS! And how the "driver" electronics is set up ... The DSC stabilization system prevents slips unobtrusively, but powerfully and confidently. Contrary to all motorsport canons, on the BMW Z4 you can safely put pressure on the gas or slow down in a turn - the computer will instantly remove excess traction or recalculate the necessary balance of braking forces on each wheel. In this case, a single press of the DSC button does not turn off the stabilization system, as usual, but activates DTC - Dynamic Traction Control. As the Bavarians say, this is some kind of compensation for the lack of a self-locking differential on the Z4 - DTC activation allows for some “controlled” slippage of the drive wheels. But with the development of a skid, the electronics immediately “wakes up” and pulls the drivers. The "asphalt" roadster is not designed for rally driving!

The Sport version has a very stiff suspension. The deep sound of the in-line "six" fills the cabin - even open, with the roof folded. If the voice of the engine were a little louder, you could call it importunate ... A trip in the "comfortable" version causes more pleasant emotions. On 16" wheels instead of 17", no "sport" button. The roadster reacts calmer to steering turns, the exhaust sound is not so aggressive, the suspension “swallows” bumps noticeably softer. Such a car is more predictable and understandable!

Perhaps the flaws in the habits of the "sporty" roadster are largely due to the other wheels. For example, on longitudinal waves of asphalt, the steering wheel of a car with a “sports” suspension begins to tilt towards the slope - this happens when the so-called running-in shoulder of the steered wheels changes due to the installation of wheels with a different offset. A "comfortable" roadster on the same slope quietly goes straight, not reacting to the road profile. And the BMW Z4 3.0i Comfort is hardly slower than the "sporty" version.

By the way, despite the “fast” rack and pinion steering with a very low gear ratio (14.2), the steering wheel on the Z4 makes more than three turns from lock to lock. Due to this, the front wheels turn at a very large angle. The turning circle, respectively, of the roadster is less than ten meters - excellent maneuverability!

It debuted at the 2002 Paris Auto Show and was built at BMW's US plant in Greer, South Carolina, and starting with the 2009 model year, the second generation Z4 is built in Regensburg, Germany.

The design of the first Z 4 was created by Chris Bangle, and as for the mechanics, the engines for the car were taken mainly from and.
